*
* \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.
* \warning You must keep the maximum use of your counter in mind.
*
* \param ctx The AES context to use for encryption or decryption.
* It must be initialized and bound to a key.

* \brief This function performs an ARIA-CTR encryption or decryption
* operation.
*
* 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.
* \param nc_off The offset in Bytes in the current \p stream_block,
* for resuming within the current cipher stream. The
* offset pointer should be \c 0 at the start of a
* stream. This must not be larger than \c 15 Bytes.
* \param nonce_counter The 128-bit nonce and counter. This must point to
* a read/write buffer of length \c 16 bytes.
* \param stream_block The saved stream block for resuming. This must
* point to a read/write buffer of length \c 16 bytes.
* This is overwritten by the function.
* \param input The buffer holding the input data. This must
* be a readable buffer of length \p length Bytes.
* \param output The buffer holding the output data. This must
* be a writable buffer of length \p length Bytes.
*

* Mismatching tags lead to an error.
* For example, a value of \c 0 for both \p tag_must_mask

* while a value of \c 0xFF for \p tag_must_mask means
* that \p tag_must_val is the only allowed tag.

* \param tag_may_val The desired value of each ASN.1 tag found in the
* SEQUENCE, after masking with \p tag_may_mask.
* Mismatching tags will be silently ignored.
* For example, a value of \c 0 for \p tag_may_mask and
* \p tag_may_val means that any tag will be considered,
* while a value of \c 0xFF for \p tag_may_mask means
* that all tags with value different from \p tag_may_val
* will be ignored.
* \param cb The callback to trigger for each component
* in the ASN.1 SEQUENCE. If the callback returns

*
* \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.
* Warning: You have to keep the maximum use of your counter in mind!
*
* 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 ctx Blowfish context
* \param length The length of the data
* \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

* mbedtls_camellia_setkey_enc() regardless of whether \p mode
* is #MBEDTLS_CAMELLIA_ENCRYPT or #MBEDTLS_CAMELLIA_DECRYPT.
* Warning: You have to keep the maximum use of your counter in mind!
*
* \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.
* Note: Due to the nature of CTR you should use the same key schedule for
* both encryption and decryption. So a context initialized with
* mbedtls_camellia_setkey_enc() for both MBEDTLS_CAMELLIA_ENCRYPT and MBEDTLS_CAMELLIA_DECRYPT.
*
* 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
* \param ctx CAMELLIA context
* \param length The length of the data
* \param nc_off The offset in the current 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
* read/write buffer of length \c 16 Bytes.

/**
* \file ctr_drbg.h
*
* \brief This file contains definitions and functions for the
* CTR_DRBG pseudorandom generator.
* \brief CTR_DRBG is based on AES-256, as defined in <em>NIST SP 800-90A:
* Recommendation for Random Number Generation Using Deterministic
* Random Bit Generators</em>.
*
* 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.

* \param custom Personalization data (Device specific identifiers)
* (Can be NULL)
* \param len Length of personalization data
*
* A typical choice for the \p f_entropy and \p p_entropy parameters is
* to use the entropy module:
* - \p f_entropy is mbedtls_entropy_func();
* - \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.
*
* \note By default, the security strength as defined by NIST is:
* - 128 bits if \p md_info is SHA-1;
* - 192 bits if \p md_info is SHA-224;
* - 256 bits if \p md_info is SHA-256, SHA-384 or SHA-512.
* \note The "security strength" as defined by NIST is set to:
* 128 bits if md_alg is SHA-1,
* 192 bits if md_alg is SHA-224,
* 256 bits if md_alg is SHA-256 or higher.
* Note that SHA-256 is just as efficient as SHA-224.
* The security strength can be reduced if a smaller
* entropy length is set with
* mbedtls_hmac_drbg_set_entropy_len().
*
* \note The default entropy length is the security strength
* (converted from bits to bytes). You can override
* it by calling mbedtls_hmac_drbg_set_entropy_len().
*
* \note During the initial seeding, this function calls
* the entropy source to obtain a nonce
* whose length is half the entropy length.
