2022-10-10[crypto] Simplify internal HMAC APIMichael Brown1-0/+3
Simplify the internal HMAC API so that the key is provided only at the point of calling hmac_init(), and the (potentially reduced) key is stored as part of the context for later use by hmac_final(). This simplifies the calling code, and avoids the need for callers such as TLS to allocate a potentially variable length block in order to retain a copy of the unmodified key.

2015-04-12[crypto] Add SHA-512 algorithmMichael Brown1-0/+3
This implementation has been verified using the NIST SHA-512 test vectors. Signed-off-by: Michael Brown <mcb30@ipxe.org>
2015-04-12[crypto] Add SHA-224 algorithmMichael Brown1-0/+12
SHA-224 is almost identical to SHA-256, with differing initial hash values and a truncated output length. This implementation has been verified using the NIST SHA-224 test vectors. Signed-off-by: Michael Brown <mcb30@ipxe.org>
