[PATCH RFC v2 1/5] lib: Rename rsa-checksum.c to hash-checksum.c

Alexandru Gagniuc
2020-12-30T21:00:23Z

rsa-checksum.c sontains the hash_calculate() implementations. Despite
the "rsa-" file prefix, this function is useful for other algorithms.

To prevent confusion, move this file to lib/crypto, and rename it to
hash-checksum.c, to give it a more "generic" feel.
