+ * crypt/sha2.h, crypt/Versions: new header for -lcrypt, with new exports.
+ * crypt/sha512.c, sha256.c sha512.c sha512.h:
+ New functions: sha384_finish(), sha224_finish(), sha256(), sha512()
+ Add crypt/align.h, *_finish() functions no longer require aligned digest.
+ *_finish() functions now return pointer to digest.
+ sha256_update(), sha512_update() now return pointer to data parameter.
+ Rename struct sha256_ctx => sha256_ctx, and struct sha512_ctx => sha512_ctx.
+ Move sha256_ctx.buflen after sha256_ctx.buffer so that sha256_ctx.buffer
+ is 128-bit aligned.
+ Add padding to sha512_ctx so that sha512_ctx.buffer is 128-bit aligned.
+ (sha256_update, sha512_update, sha256_finish, sha224_finish, sha512_finish,
+ sha384_finish): make pointer arguments __restrict.
+ (__sha256_process_bytes, __sha512_process_bytes): change parameter order to match
+ sha256_update(), sha512_update().
+ * sysdeps: Add to ABI.
+ * configure.ac: use pkg-config instead of nss-config
