The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
crypto_shash_digest – calculate message digest for buffer Synopsis int crypto_shash_digest(struct shash_desc *desc, const u8 *data, unsigned int len, u8 *out); Arguments desc see crypto_shash_final data see crypto_shash_update len see crypto_shash_update out see crypto_shash_final Description This function is a “short-hand” for the function calls of crypto_shash_init, crypto_shash_update and crypto_shash_final. The parameters have the same meaning as…
crypto_shash_descsize – obtain the operational state size Synopsis unsigned int crypto_shash_descsize(struct crypto_shash *tfm); Arguments tfm cipher handle Description The size of the operational state the cipher needs during operation is returned for the hash referenced with the cipher handle. This size is required to calculate the memory requirements to allow the caller allocating sufficient memory…

Return block size of cipher Authors Stephan Mueller <smueller [at] chronox.de> Author. Marek Vasut <marek [at] denx.de> Author. Copyright
crypto_rng_seedsize – obtain seed size of RNG Synopsis int crypto_rng_seedsize(struct crypto_rng *tfm); Arguments tfm cipher handle Description The function returns the seed size for the random number generator referenced by the cipher handle. This value may be zero if the random number generator does not implement or require a reseeding. For example, the SP800-90A DRBGs…
crypto_rng_reset – re-initialize the RNG Synopsis int crypto_rng_reset(struct crypto_rng *tfm, const u8 *seed, unsigned int slen); Arguments tfm cipher handle seed seed input data slen length of the seed input data Description The reset function completely re-initializes the random number generator referenced by the cipher handle by clearing the current state. The new state is…
crypto_rng_get_bytes – get random number Synopsis int crypto_rng_get_bytes(struct crypto_rng *tfm, u8 *rdata, unsigned int dlen); Arguments tfm cipher handle rdata output buffer holding the random numbers dlen length of the output buffer Description This function fills the caller-allocated buffer with random numbers using the random number generator referenced by the cipher handle. Return 0 function…
crypto_rng_generate – get random number Synopsis int crypto_rng_generate(struct crypto_rng *tfm, const u8 *src, unsigned int slen, u8 *dst, unsigned int dlen); Arguments tfm cipher handle src Input buffer holding additional data, may be NULL slen Length of additional data dst output buffer holding the random numbers dlen length of the output buffer Description This function…
