2015-07-08crypto: add a nettle cipher implementationDaniel P. Berrange
If we are linking to gnutls already and gnutls is built against nettle, then we should use nettle as a cipher backend in preference to our built-in backend. This will be used when linking against some GNUTLS 2.x versions and all GNUTLS 3.x versions. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> Message-Id: <1435770638-25715-7-git-send-email-berrange@redhat.com> [Change "#elif" to "#elif defined". - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-07-08crypto: add a gcrypt cipher implementationDaniel P. Berrange
If we are linking to gnutls already and gnutls is built against gcrypt, then we should use gcrypt as a cipher backend in preference to our built-in backend. This will be used when linking against GNUTLS 1.x and many GNUTLS 2.x versions. Signed-off-by: Daniel P.

2015-07-08crypto: introduce generic cipher API & built-in implementationDaniel P. Berrange
Introduce a generic cipher API and an implementation of it that supports only the built-in AES and DES-RFB algorithms. The test suite checks the supported algorithms + modes to validate that every backend implementation is actually correctly complying with the specs. Signed-off-by: Daniel P.
