#Types

#fio_sha256_s

c
typedef struct {

} fio_sha256_s

Streaming SHA-256 type.

Symbol type: type

#fio_sha512_s

c
typedef struct {
fio_u512 hash;
fio_u1024 cache;
uint64_t total_len;
} fio_sha512_s

Streaming SHA-512 type.

Symbol type: type

#Functions

#fio_sha256

c
inline fio_u256 fio_sha256(const void *data, uint64_t len)

A simple, non streaming, implementation of the SHA-256 hashing algorithm.

Symbol type: function

#fio_sha256_init

c
inline fio_sha256_s fio_sha256_init(void)

initializes a fio_u256 so the hash can consume streaming data.

Symbol type: function

#fio_sha256_consume

c
void fio_sha256_consume(fio_sha256_s *h, const void *data, uint64_t len)

Feed data into the hash

Symbol type: function

#fio_sha256_finalize

c
fio_u256 fio_sha256_finalize(fio_sha256_s *h)

finalizes a fio_u256 with the SHA 256 hash.

Symbol type: function

#fio_sha512

c
inline fio_u512 fio_sha512(const void *data, uint64_t len)

A simple, non streaming, implementation of the SHA-512 hashing algorithm.

Symbol type: function

#fio_sha512_init

c
inline fio_sha512_s fio_sha512_init(void)

initializes a fio_u512 so the hash can consume streaming data.

Symbol type: function

#fio_sha512_consume

c
void fio_sha512_consume(fio_sha512_s *h, const void *data, uint64_t len)

Feed data into the hash

Symbol type: function

#fio_sha512_finalize

c
fio_u512 fio_sha512_finalize(fio_sha512_s *h)

finalizes a fio_u512 with the SHA 512 hash.

Symbol type: function

#fio_sha384_init

c
inline fio_sha512_s fio_sha384_init(void)

initializes a fio_u512 so the hash can consume streaming data (SHA-384).

SHA-384 is SHA-512 with different initial values, truncated to 48 bytes. NOTE: truncating a SHA-512 result is NOT the same as SHA-384.

Symbol type: function

#fio_sha384_consume

c
#define fio_sha384_consume fio_sha512_consume

Feed data into the hash

Note: this may be a macro only / macro wrapper for a function.

Symbol type: macro

#fio_sha384_finalize

c
#define fio_sha384_finalize fio_sha512_finalize

finalizes a fio_u512 with the SHA 384 hash (first 48 bytes are the hash).

Note: this may be a macro only / macro wrapper for a function.

Symbol type: macro

#fio_sha384

c
inline fio_u512 fio_sha384(const void *data, uint64_t len)

A simple, non streaming, implementation of the SHA-384 hashing algorithm. Returns a fio_u512 of which the first 48 bytes hold the SHA-384 hash.

Symbol type: function
