SHA-1 and SHA-256 (Secure Hash Algorithm) hash function implementations.
This module supports the following SHA hash functions:
- SHA-1: 160 bits
- SHA-224: 224 bits, as a variant of SHA-2
- SHA-256: 256 bits, as a variant of SHA-2
- See also
- For SHA-384, SHA-512, and variants thereof, see SHA-512.
◆ av_sha_alloc()
struct AVSHA * av_sha_alloc |
( |
