The branch stable/13 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=3a7ae9ce6dcea8cc5beb0dc3284e1b50a60eff1e commit 3a7ae9ce6dcea8cc5beb0dc3284e1b50a60eff1e Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2021-02-18 17:23:36 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2021-10-21 15:51:22 +0000 cryptocheck: Add Chacha20-Poly1305 AEAD coverage. - Make openssl_gcm_encrypt generic to AEAD ciphers (aside from CCM) and use it for Chacha20-Poly1305. - Use generic AEAD control constants instead of GCM/CCM specific names.
