- * \warning You must keep the maximum use of your counter in mind.
+ * \warning You must never reuse a nonce value with the same key. Doing so

+ *
+ * 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.

+ * 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

+ * 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.

+ * - mbedtls_rsa_deduce_private_exponent
+ * - mbedtls_rsa_deduce_crt
+ * Each of these functions takes a set of core RSA parameters and

+ * Percival's blog article at:
+ *
+ * http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
+ *
+ * It uses a volatile function pointer to the standard memset(). Because the
+ * pointer is volatile the compiler expects it to change at
+ * any time and will not optimize out the call that could potentially perform
+ * other operations on the input buffer instead of just setting it to 0.
+ * Nevertheless, as pointed out by davidtgoldblatt on Hacker News
+ * (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
+ * details), optimizations of the following form are still possible:
+ *
+ * if( memset_func != memset )
+ * memset_func( buf, 0, len );
+ *
+ * Note that it is extremely difficult to guarantee that
+ * mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
+ * in a portable way. For this reason, Mbed TLS also provides the configuration
+ * option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
+ * mbedtls_platform_zeroize() to use a suitable implementation for their
+ * platform and needs.
