*
|
||||
* \brief This file contains AES definitions and functions.
|
||||
*
|
||||
* The Advanced Encryption Standard (AES) specifies a FIPS-approved
|
||||
* cryptographic algorithm that can be used to protect electronic
|
||||
* data.
|
||||
*
|
||||
* The AES algorithm is a symmetric block cipher that can
|
||||
* encrypt and decrypt information. For more information, see
|
||||
* <em>FIPS Publication 197: Advanced Encryption Standard</em> and
|
||||
* <em>ISO/IEC 18033-2:2006: Information technology -- Security
|
||||
* techniques -- Encryption algorithms -- Part 2: Asymmetric
|
||||
* ciphers</em>.
|
||||
*
|
||||
* The AES-XTS block mode is standardized by NIST SP 800-38E
|
||||
* <https://nvlpubs.nist.gov/nistpubs/legacy/sp/nistspecialpublication800-38e.pdf>
|
||||
* and described in detail by IEEE P1619

|

|
||||
*
|
||||
* Due to the nature of CTR, you must use the same key schedule
|

* for both encryption and decryption operations. Therefore, you
|
||||
* must use the context initialized with mbedtls_aes_setkey_enc()
|

* for both #MBEDTLS_AES_ENCRYPT and #MBEDTLS_AES_DECRYPT.
|
||||
*
|
||||
* \warning You must never reuse a nonce value with the same key. Doing so
|
||||
* would void the encryption for the two messages encrypted with
|
||||
* the same nonce and key.
|
||||
*
|
||||
* There are two common strategies for managing nonces with CTR:
|
||||
*
|
||||
* 1. You can handle everything as a single message processed over
|
||||
* successive calls to this function. In that case, you want to
|
||||
* set \p nonce_counter and \p nc_off to 0 for the first call, and
|
||||
* then preserve the values of \p nonce_counter, \p nc_off and \p
|
||||
* stream_block across calls to this function as they will be
|
||||
* updated by this function.
|
||||
*
|
||||
* With this strategy, you must not encrypt more than 2**128
|
||||
* blocks of data with the same key.
|
||||
*
|
||||
* 2. You can encrypt separate messages by dividing the \p
|
||||
* nonce_counter buffer in two areas: the first one used for a
|
||||
* per-message nonce, handled by yourself, and the second one
|
||||
* updated by this function internally.
|
||||
*
|
||||
* For example, you might reserve the first 12 bytes for the
|
||||
* per-message nonce, and the last 4 bytes for internal use. In that
|
||||
* case, before calling this function on a new message you need to
|
||||
* set the first 12 bytes of \p nonce_counter to your chosen nonce
|
||||
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
|
||||
* stream_block to be ignored). That way, you can encrypt at most
|
||||
* 2**96 messages of up to 2**32 blocks each with the same key.
|
||||
*
|
||||
* The per-message nonce (or information sufficient to reconstruct
|
||||
* it) needs to be communicated with the ciphertext and must be unique.
|
||||
* The recommended way to ensure uniqueness is to use a message
|
||||
* counter. An alternative is to generate random nonces, but this
|
||||
* limits the number of messages that can be securely encrypted:
|
||||
* for example, with 96-bit random nonces, you should not encrypt
|
||||
* more than 2**32 messages with the same key.
|
||||
*
|
||||
* Note that for both stategies, sizes are measured in blocks and
|
||||
* that an AES block is 16 bytes.
|
||||
*
|
||||
* \warning Upon return, \p stream_block contains sensitive data. Its
|
||||
* content must not be written to insecure storage and should be
|
||||
* securely discarded as soon as it's no longer needed.
|
||||
*
|
||||
* \param ctx The AES context to use for encryption or decryption.
|
||||
* It must be initialized and bound to a key.
|
||||
* \param length The length of the input data.
|
||||
* \param nc_off The offset in the current \p stream_block, for
|
||||
* resuming within the current cipher stream. The
|
||||
* offset pointer should be 0 at the start of a stream.
|
||||
* It must point to a valid \c size_t.

|

* This function performs the operation defined in the \p mode
|
||||
* parameter (encrypt/decrypt), on the input data buffer
|
||||
* defined in the \p input parameter.
|
||||
*
|
||||
* Due to the nature of CTR, you must use the same key schedule
|
||||
* for both encryption and decryption operations. Therefore, you
|
||||
* must use the context initialized with mbedtls_aria_setkey_enc()
|
||||
* for both #MBEDTLS_ARIA_ENCRYPT and #MBEDTLS_ARIA_DECRYPT.
|
||||
*
|
||||
* \warning You must never reuse a nonce value with the same key. Doing so
|
||||
* would void the encryption for the two messages encrypted with
|
||||
* the same nonce and key.
|
||||
*
|
||||
* There are two common strategies for managing nonces with CTR:
|
||||
*
|
||||
* 1. You can handle everything as a single message processed over
|
||||
* successive calls to this function. In that case, you want to
|
||||
* set \p nonce_counter and \p nc_off to 0 for the first call, and
|
||||
* then preserve the values of \p nonce_counter, \p nc_off and \p
|
||||
* stream_block across calls to this function as they will be
|
||||
* updated by this function.
|
||||
*
|
||||
* With this strategy, you must not encrypt more than 2**128
|
||||
* blocks of data with the same key.
|
||||
*
|
||||
* 2. You can encrypt separate messages by dividing the \p
|
||||
* nonce_counter buffer in two areas: the first one used for a
|
||||
* per-message nonce, handled by yourself, and the second one
|
||||
* updated by this function internally.
|
||||
*
|
||||
* For example, you might reserve the first 12 bytes for the
|
||||
* per-message nonce, and the last 4 bytes for internal use. In that
|
||||
* case, before calling this function on a new message you need to
|
||||
* set the first 12 bytes of \p nonce_counter to your chosen nonce
|
||||
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
|
||||
* stream_block to be ignored). That way, you can encrypt at most
|
||||
* 2**96 messages of up to 2**32 blocks each with the same key.
|
||||
*
|
||||
* The per-message nonce (or information sufficient to reconstruct
|
||||
* it) needs to be communicated with the ciphertext and must be unique.
|
||||
* The recommended way to ensure uniqueness is to use a message
|
||||
* counter. An alternative is to generate random nonces, but this
|
||||
* limits the number of messages that can be securely encrypted:
|
||||
* for example, with 96-bit random nonces, you should not encrypt
|
||||
* more than 2**32 messages with the same key.
|
||||
*
|
||||
* Note that for both stategies, sizes are measured in blocks and
|
||||
* that an ARIA block is 16 bytes.
|
||||
*
|
||||
* \warning Upon return, \p stream_block contains sensitive data. Its
|
||||
* content must not be written to insecure storage and should be
|
||||
* securely discarded as soon as it's no longer needed.
|
||||
*
|
||||
* \param ctx The ARIA context to use for encryption or decryption.
|
||||
* This must be initialized and bound to a key.
|
||||
* \param length The length of the input data \p input in Bytes.

*
|
||||
* \warning You must never reuse a nonce value with the same key. Doing so
|
||||
* would void the encryption for the two messages encrypted with
|
||||
* the same nonce and key.
|
||||
*
|
||||
* There are two common strategies for managing nonces with CTR:
|
||||
*
|
||||
* 1. You can handle everything as a single message processed over
|
||||
* successive calls to this function. In that case, you want to
|
||||
* set \p nonce_counter and \p nc_off to 0 for the first call, and
|
||||
* then preserve the values of \p nonce_counter, \p nc_off and \p
|
||||
* stream_block across calls to this function as they will be
|
||||
* updated by this function.
|
||||
*
|
||||
* With this strategy, you must not encrypt more than 2**64
|
||||
* blocks of data with the same key.
|
||||
*
|
||||
* 2. You can encrypt separate messages by dividing the \p
|
||||
* nonce_counter buffer in two areas: the first one used for a
|
||||
* per-message nonce, handled by yourself, and the second one
|
||||
* updated by this function internally.
|
||||
*
|
||||
* For example, you might reserve the first 4 bytes for the
|
||||
* per-message nonce, and the last 4 bytes for internal use. In that
|
||||
* case, before calling this function on a new message you need to
|
||||
* set the first 4 bytes of \p nonce_counter to your chosen nonce
|
||||
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
|
||||
* stream_block to be ignored). That way, you can encrypt at most
|
||||
* 2**32 messages of up to 2**32 blocks each with the same key.
|
||||
*
|
||||
* The per-message nonce (or information sufficient to reconstruct
|
||||
* it) needs to be communicated with the ciphertext and must be unique.
|
||||
* The recommended way to ensure uniqueness is to use a message
|
||||
* counter.
|
||||
*
|
||||
* Note that for both stategies, sizes are measured in blocks and
|
||||
* that a Blowfish block is 8 bytes.
|
||||
*
|
||||
* \warning Upon return, \p stream_block contains sensitive data. Its
|
||||
* content must not be written to insecure storage and should be
|
||||
* securely discarded as soon as it's no longer needed.
|
||||
*
|
||||
* \param ctx The Blowfish context to use. This must be initialized
|
||||
* and bound to a key.
|
||||
* \param length The length of the input data in Bytes.
|
||||
* \param nc_off The offset in the current stream_block (for resuming
|
||||
* within current cipher stream). The offset pointer
|
||||
* should be \c 0 at the start of a stream and must be
|
||||
* smaller than \c 8. It is updated by this function.
|
||||
* \param nonce_counter The 64-bit nonce and counter. This must point to a
|
||||
* read/write buffer of length \c 8 Bytes.
|
||||
* \param stream_block The saved stream-block for resuming. This must point to
|
||||
* a read/write buffer of length \c 8 Bytes.
|
||||
* \param input The input data. This must be a readable buffer of
|
||||
* length \p length Bytes.
|
||||
* \param output The output data. This must be a writable buffer of
|
||||
* length \p length Bytes.

* would void the encryption for the two messages encrypted with
|
||||
* the same nonce and key.
|
||||
*
|
||||
* There are two common strategies for managing nonces with CTR:
|
||||
*
|
||||
* 1. You can handle everything as a single message processed over
|
||||
* successive calls to this function. In that case, you want to
|
||||
* set \p nonce_counter and \p nc_off to 0 for the first call, and
|
||||
* then preserve the values of \p nonce_counter, \p nc_off and \p
|
||||
* stream_block across calls to this function as they will be
|
||||
* updated by this function.
|
||||
*
|
||||
* With this strategy, you must not encrypt more than 2**128
|
||||
* blocks of data with the same key.
|
||||
*
|
||||
* 2. You can encrypt separate messages by dividing the \p
|
||||
* nonce_counter buffer in two areas: the first one used for a
|
||||
* per-message nonce, handled by yourself, and the second one
|
||||
* updated by this function internally.
|
||||
*
|
||||
* For example, you might reserve the first \c 12 Bytes for the
|
||||
* per-message nonce, and the last \c 4 Bytes for internal use.
|
||||
* In that case, before calling this function on a new message you
|
||||
* need to set the first \c 12 Bytes of \p nonce_counter to your
|
||||
* chosen nonce value, the last four to \c 0, and \p nc_off to \c 0
|
||||
* (which will cause \p stream_block to be ignored). That way, you
|
||||
* can encrypt at most \c 2**96 messages of up to \c 2**32 blocks
|
||||
* each with the same key.
|
||||
*
|
||||
* The per-message nonce (or information sufficient to reconstruct
|
||||
* it) needs to be communicated with the ciphertext and must be
|
||||
* unique. The recommended way to ensure uniqueness is to use a
|
||||
* message counter. An alternative is to generate random nonces,
|
||||
* but this limits the number of messages that can be securely
|
||||
* encrypted: for example, with 96-bit random nonces, you should
|
||||
* not encrypt more than 2**32 messages with the same key.
|
||||
*
|
||||
* Note that for both stategies, sizes are measured in blocks and
|
||||
* that a CAMELLIA block is \c 16 Bytes.
|
||||
*
|
||||
* \warning Upon return, \p stream_block contains sensitive data. Its
|
||||
* content must not be written to insecure storage and should be
|
||||
* securely discarded as soon as it's no longer needed.
|
||||
*
|
||||
* \param ctx The CAMELLIA context to use. This must be initialized
|
||||
* and bound to a key.
|
||||
* \param length The length of the input data \p input in Bytes.
|
||||
* Any value is allowed.
|
||||
* \param nc_off The offset in the current \p stream_block (for resuming
|
||||
* within current cipher stream). The offset pointer to
|
||||
* should be \c 0 at the start of a stream. It is updated
|
||||
* at the end of this call.
|
||||
* \param nonce_counter The 128-bit nonce and counter. This must be a read/write
|
||||
* buffer of length \c 16 Bytes.
|
||||
* \param stream_block The saved stream-block for resuming. This must be a

* \file ctr_drbg.h
|
||||
*
|
||||
* \brief This file contains definitions and functions for the
|
||||
* CTR_DRBG pseudorandom generator.
|
||||
*
|
||||
* CTR_DRBG is a standardized way of building a PRNG from a block-cipher
|
||||
* in counter mode operation, as defined in <em>NIST SP 800-90A:
|
||||
* Recommendation for Random Number Generation Using Deterministic Random
|
||||
* Bit Generators</em>.
|
||||
*
|
||||
* The Mbed TLS implementation of CTR_DRBG uses AES-256 (default) or AES-128
|
||||
* (if \c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY is enabled at compile time)
|
||||
* as the underlying block cipher, with a derivation function.
|
||||
* The initial seeding grabs #MBEDTLS_CTR_DRBG_ENTROPY_LEN bytes of entropy.
|
||||
* See the documentation of mbedtls_ctr_drbg_seed() for more details.
|
||||
*
|
||||
* Based on NIST SP 800-90A §10.2.1 table 3 and NIST SP 800-57 part 1 table 2,
|
||||
* here are the security strengths achieved in typical configuration:
|
||||
* - 256 bits under the default configuration of the library, with AES-256
|
||||
* and with #MBEDTLS_CTR_DRBG_ENTROPY_LEN set to 48 or more.
|
||||
* - 256 bits if AES-256 is used, #MBEDTLS_CTR_DRBG_ENTROPY_LEN is set
|
||||
* to 32 or more, and the DRBG is initialized with an explicit
|
||||
* nonce in the \c custom parameter to mbedtls_ctr_drbg_seed().
|
||||
* - 128 bits if AES-256 is used but #MBEDTLS_CTR_DRBG_ENTROPY_LEN is
|
||||
* between 24 and 47 and the DRBG is not initialized with an explicit
|
||||
* nonce (see mbedtls_ctr_drbg_seed()).
|
||||
* - 128 bits if AES-128 is used (\c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY enabled)
|
||||
* and #MBEDTLS_CTR_DRBG_ENTROPY_LEN is set to 24 or more (which is
|
||||
* always the case unless it is explicitly set to a different value
|
||||
* in config.h).
|
||||
*
|
||||
* Note that the value of #MBEDTLS_CTR_DRBG_ENTROPY_LEN defaults to:
|
||||
* - \c 48 if the module \c MBEDTLS_SHA512_C is enabled and the symbol
|
||||
* \c MBEDTLS_ENTROPY_FORCE_SHA256 is disabled at compile time.
|
||||
* This is the default configuration of the library.
|
||||
* - \c 32 if the module \c MBEDTLS_SHA512_C is disabled at compile time.
|
||||
* - \c 32 if \c MBEDTLS_ENTROPY_FORCE_SHA256 is enabled at compile time.

* - \p p_entropy is an instance of ::mbedtls_entropy_context initialized
|

* with mbedtls_entropy_init() (which registers the platform's default
|
||||
* entropy sources).
|
||||
*
|
||||
* You can provide a personalization string in addition to the
|

* entropy source, to make this instantiation as unique as possible.

|

* mbedtls_hmac_drbg_set_entropy_len().
|
||||

|

* it by calling mbedtls_hmac_drbg_set_entropy_len().

* Compute RSA prime factors from public and private exponents
|
||||
*
|
||||
* Summary of algorithm:
|
||||
* Setting F := lcm(P-1,Q-1), the idea is as follows:
|
||||
*
|
||||
* (a) For any 1 <= X < N with gcd(X,N)=1, we have X^F = 1 modulo N, so X^(F/2)
|
||||
* is a square root of 1 in Z/NZ. Since Z/NZ ~= Z/PZ x Z/QZ by CRT and the
|
||||
* square roots of 1 in Z/PZ and Z/QZ are +1 and -1, this leaves the four
|
||||
* possibilities X^(F/2) = (+-1, +-1). If it happens that X^(F/2) = (-1,+1)
|
||||
* or (+1,-1), then gcd(X^(F/2) + 1, N) will be equal to one of the prime
|
||||
* factors of N.
|
||||
*
|
||||
* (b) If we don't know F/2 but (F/2) * K for some odd (!) K, then the same
|
||||
* construction still applies since (-)^K is the identity on the set of
|
||||
* roots of 1 in Z/NZ.
|
||||
*
|
||||
* The public and private key primitives (-)^E and (-)^D are mutually inverse
|
||||
* bijections on Z/NZ if and only if (-)^(DE) is the identity on Z/NZ, i.e.
|
||||
* if and only if DE - 1 is a multiple of F, say DE - 1 = F * L.
|
||||
* Splitting L = 2^t * K with K odd, we have
|
||||
*
|
||||
* DE - 1 = FL = (F/2) * (2^(t+1)) * K,
|
||||
*
|
||||
* so (F / 2) * K is among the numbers
|
||||
*
|
||||
* (DE - 1) >> 1, (DE - 1) >> 2, ..., (DE - 1) >> ord
|
||||
*
|
||||
* where ord is the order of 2 in (DE - 1).
|
||||
* We can therefore iterate through these numbers apply the construction
|
||||
* of (a) and (b) above to attempt to factor N.

* \brief Context-independent RSA helper functions
|
||||
*
|
||||
* This module declares some RSA-related helper functions useful when
|
||||
* implementing the RSA interface. These functions are provided in a separate
|
||||
* compilation unit in order to make it easy for designers of alternative RSA
|
||||
* implementations to use them in their own code, as it is conceived that the
|
||||
* functionality they provide will be necessary for most complete
|
||||
* implementations.
|
||||
*
|
||||
* End-users of Mbed TLS who are not providing their own alternative RSA
|
||||
* implementations should not use these functions directly, and should instead
|
||||
* use only the functions declared in rsa.h.
|
||||
*
|
||||
* The interface provided by this module will be maintained through LTS (Long
|
||||
* Term Support) branches of Mbed TLS, but may otherwise be subject to change,
|
||||
* and must be considered an internal interface of the library.
|
||||
*
|
||||
* There are two classes of helper functions:
|
||||
*
|
||||
* (1) Parameter-generating helpers. These are:
|
||||
* - mbedtls_rsa_deduce_primes
|
||||
* - mbedtls_rsa_deduce_private_exponent
|
||||
* - mbedtls_rsa_deduce_crt
|
||||
* Each of these functions takes a set of core RSA parameters and
|
||||
* generates some other, or CRT related parameters.
|
||||
*
|
||||
* (2) Parameter-checking helpers. These are:
|
||||
* - mbedtls_rsa_validate_params
|
||||
* - mbedtls_rsa_validate_crt
|
||||
* They take a set of core or CRT related RSA parameters and check their
|
||||
* validity.

||||
