[src]
SHA-2 family (Secure Hash Algorithm)
General info
| Name | Digest size | Block size | Rounds | Structure | Reference |
|---|---|---|---|---|---|
| SHA-224 | 224 bits | 512 bits | 64 | Merkle–Damgård | FIPS 180-4 |
| SHA-256 | 256 bits | 512 bits | 64 | Merkle–Damgård | FIPS 180-4 |
| SHA-384 | 384 bits | 1024 bits | 80 | Merkle–Damgård | FIPS 180-4 |
| SHA-512 | 512 bits | 1024 bits | 80 | Merkle–Damgård | FIPS 180-4 |
| SHA-512/224 | 224 bits | 1024 bits | 80 | Merkle–Damgård | FIPS 180-4 |
| SHA-512/256 | 256 bits | 1024 bits | 80 | Merkle–Damgård | FIPS 180-4 |
Warning
SHA-384, SHA-512, SHA-512/224 and SHA-512/256 implementations are specified to manage messages with legth at most 2128 - 1 bits length. Due to simplification of implementation this library currently manage messages with length at most 264 - 1 bits which is reasonable for most usages (2 EB which is greater than maximum partition size in ext4).
