* qapi/crypto: Rename QCryptoCipherAlgorithm to *Algo, and drop prefixMarkus Armbruster2024-09-101-19/+19
| | | | | | | | | | | | | | | | | | | | | | QAPI's 'prefix' feature can make the connection between enumeration type and its constants less than obvious. It's best used with restraint. QCryptoCipherAlgorithm has a 'prefix' that overrides the generated enumeration constants' prefix to QCRYPTO_CIPHER_ALG. We could simply drop 'prefix', but then the prefix becomes QCRYPTO_CIPHER_ALGORITHM, which is rather long. We could additionally rename the type to QCryptoCipherAlg, but I think the abbreviation "alg" is less than clear. Rename the type to QCryptoCipherAlgo instead. The prefix becomes QCRYPTO_CIPHER_ALGO.

* crypto: add gnutls cipher providerDaniel P. Berrangé2021-07-141-0/+335
Add an implementation of the QEMU cipher APIs to the gnutls crypto backend. XTS support is only available for gnutls version >= 3.6.8. Since ECB mode is not exposed by gnutls APIs, we can't use the private XTS code for compatibility. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
