[gnutls-devel] GnuTLS | WIP: Add Linux kernel AF_ALG backend (!1404)

[Read-only notification of GnuTLS library development activities]

Stephan Mueller started a new discussion on lib/accelerated/afalg.c: https://gitlab.com/gnutls/gnutls/-/merge_requests/1404#note_543279568

Just to clarify: Is the GnuTLS API here only providing access to block cipher modes (e.g. CBC)? Or do we also have stream-cipher modes (CTR, CTS)?

Note, in case of stream ciphers, the call kcapi_cipher_stream_update_last() is necessary to handle the last block that may not be a multiple of the block size any more.

How does GnuTLS the case of stream ciphers when invoking the enc/dec operation multiple times?
