[gnutls-devel] GnuTLS | crypto-api: support SIV ciphers with encryptv2 functions (!1515)

[Read-only notification of GnuTLS library development activities]

Daiki Ueno created a merge request: https://gitlab.com/gnutls/gnutls/-/merge_requests/1515

Project:Branches: dueno/gnutls:wip/dueno/siv-iov to gnutls/gnutls:master
Author:   Daiki Ueno




The AES-SIV ciphers have a peculiarity that it prepends authentication
tag to the generated ciphertext rather than appending.  The
gnutls_aead_cipher_encryptv2 previously was not able to cope with that
and returned wrong authentication tag.  This patch adds a new cipher
flag GNUTLS_CIPHER_FLAG_TAG_PREFIXED to indicate it.
