Expand description
SHA-2 and the legacy SHA-1 digest algorithm.
If all the data is available in a single contiguous slice then the digest
function should be used. Otherwise, the digest can be calculated in
multiple steps using Context
.
Structs§
- Algorithm
- A digest algorithm.
- Context
- A context for multi-step (Init-Update-Finish) digest calculations.
- Digest
- A calculated digest value.
Constants§
- MAX_
BLOCK_ LEN - The maximum block length (
Algorithm::block_len()
) of all the algorithms in this module. - MAX_
CHAINING_ LEN - The maximum chaining length (
Algorithm::chaining_len()
) of all the algorithms in this module. - MAX_
OUTPUT_ LEN - The maximum output length (
Algorithm::output_len()
) of all the algorithms in this module. - SHA1_
OUTPUT_ LEN - The length of the output of SHA-1, in bytes.
- SHA256_
OUTPUT_ LEN - The length of the output of SHA-256, in bytes.

OUTPUT_ LEN - The length of the output of SHA-384, in bytes.
- SHA512_
256_ OUTPUT_ LEN - The length of the output of SHA-512/256, in bytes.
- SHA512_
OUTPUT_ LEN - The length of the output of SHA-512, in bytes.
