[PULL 2/7] crypto: Introduce akcipher crypto class

[Daniel P. Berrangé]

From: zhenwei pi <pizhenwei@bytedance.com>

Introduce new akcipher crypto class 'QCryptoAkCIpher', which supports
basic asymmetric operations: encrypt, decrypt, sign and verify.

Suggested by Daniel P. Berrangé, also add autoptr cleanup for the new
class. Thanks to Daniel!

[PULL 4/7] crypto: Implement RSA algorithm by hogweed

[Daniel P. Berrangé]

From: Lei He <helei.sig11@bytedance.com>

Implement RSA algorithm by hogweed from nettle. Thus QEMU supports
a 'real' RSA backend to handle request from guest side. It's
important to test RSA offload case without OS & hardware requirement.

[PULL 5/7] crypto: Implement RSA algorithm by gcrypt

[Daniel P. Berrangé]

From: Lei He <helei.sig11@bytedance.com>

Added gcryt implementation of RSA algorithm, RSA algorithm
implemented by gcrypt has a higher priority than nettle because
it supports raw padding.

[PULL 7/7] tests/crypto: Add test suite for RSA keys

[Daniel P. Berrangé]

From: Lei He <helei.sig11@bytedance.com>

As Daniel suggested, Add tests suite for rsakey, as a way to prove
that we can handle DER errors correctly.
