crypto: sha1 - Wrap library and add HMAC support
Like I did for crypto/sha512.c, rework crypto/sha1_generic.c (renamed to
crypto/sha1.c) to simply wrap the normal library functions instead of
accessing the low-level block function directly. Also add support for
HMAC-SHA1, again just wrapping the library functions.
Since the replacement crypto_shash algorithms are implemented using the
(potentially arch-optimized) library functions, give them driver names
ending with "-lib" rather than "-generic". Update crypto/testmgr.c and
an odd driver to take this change in driver name into account.
Note: to see the diff from crypto/sha1_generic.c to crypto/sha1.c, view
this commit with 'git show -M10'.
