Source code: src/hash/sha1.h, src/hash/sha1.c
Test code: tst/hash/main.c
Test coverage: src/hash/sha1.c
Functions
-
int
sha1_init
(struct sha1_t *self_p)¶ Initialize given SHA1 object.
- Return
- zero(0) or negative error code.
- Parameters
self_p
-SHA1 object.
-
int
sha1_update
(struct sha1_t *self_p, void *buf_p, size_t size)¶ Update the sha object with the given buffer. Repeated calls are equivalent to a single call with the concatenation of all the arguments.
- Return
- zero(0) or negative error code.
- Parameters
self_p
-SHA1 object.
buf_p
-Buffer to update the sha object with.
size
-Size of the buffer.
-
int
sha1_digest
(struct sha1_t *self_p, uint8_t *hash_p)¶ Return the digest of the strings passed to the sha1_update() method so far. This is a 20-byte value which may contain non-ASCII characters, including null bytes.
- Return
- zero(0) or negative error code.
- Parameters
self_p
-SHA1 object.
hash_p
-Hash sum.
-
struct
sha1_t
