* 2sha: Add SHA-224 and SHA-384 hash algorithmsJulius Werner2020-05-121-10/+23
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the SHA-224 and SHA-384 hash algorithms, which are basically just variants of SHA-256 and SHA-512 (respectively) with different initialization vectors and truncating a bit of the final output. They are only added to serve vboot's role as all-purpose crypto toolbox for callers (e.g. coreboot, where I need SHA-384 to support a certain SoC boot descriptor right now) and not intended for actual use as signature or firmware body hashes -- therefore, we only add the hash algorithms themselves and don't create enum values for them in enum vb2_crypto_algorithm or other structures. Also clarify the difference between UNROLL_LOOPS and UNROLL_LOOPS_SHA512 in the Makefile, since it was totally not obvious to me.

* vboot2: Add crypto functionsRandall Spangler2014-06-051-0/+346
This is the first of several CLs adding a more memory- and code-efficient firmware verification library. This CL adds the crypto library (modified from firmware/lib/cryptolib) and unit tests for it.
