Functions

void Keccak_init (keccak_state_t *ctx, unsigned int rate, unsigned int capacity, unsigned char delimitedSuffix)
 Initialise a sponge based on a keccak-1600 permutation.
 
void Keccak_update (keccak_state_t *ctx, const unsigned char *input, unsigned long long int inputByteLen)
 Absorbs data into a sponge.
 
void Keccak_final (keccak_state_t *ctx, unsigned char *output, unsigned long long int outputByteLen)
 Squeeze data from a sponge.
 
void sha3_256_init (keccak_state_t *ctx)
 SHA3-256 initialization.
 
void sha3_update (keccak_state_t *ctx, const void *data, size_t len)
 Add bytes into the hash.
 
void sha3_256_final (keccak_state_t *ctx, void *digest)
 SHA3-256 finalization.
 
void sha3_384_init (keccak_state_t *ctx)
 SHA3-384 initialization.
 
void sha3_384_final (keccak_state_t *ctx, void *digest)
 SHA3-384 finalization.
 
void sha3_512_init (keccak_state_t *ctx)
 SHA3-512 initialization.
 
void sha3_512_final (keccak_state_t *ctx, void *digest)
 SHA3-512 finalization.
 
void sha3_256 (void *digest, const void *data, size_t len)
 A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-256 from one buffer.
 
void sha3_384 (void *digest, const void *data, size_t len)
 A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-384 from one buffer.
 
void sha3_512 (void *digest, const void *data, size_t len)
 A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-512 from one buffer.
