	GLib >= 2.16 provides GChecksum API which is good enough for md5, sha1, sha256 and sha512. Use this as a final fallback if neither nettle or gcrypt are available. This lets us remove the stub hash impl, and so callers can be sure those 4 algs are always available at compile time. They may still be disabled at runtime, so a check for qcrypto_hash_supports() is still best practice to report good error messages. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2016-07-04	crypto: switch hash code to use nettle/gcrypt directly	Daniel P. Berrange
	Currently the internal hash code is using the gnutls hash APIs. GNUTLS in turn is wrapping either nettle or gcrypt. Not only were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but they don't expose support for all the algorithms QEMU needs to use with LUKS. Address this by directly wrapping nettle/gcrypt in QEMU and avoiding GNUTLS's extra layer of indirection. This gives us support for hash functions on a much wider range of platforms and opens up ability to support more hash functions. It also avoids a GNUTLS bug which would not correctly handle hashing of large data blocks if int != size_t. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
