+Subject: [PATCH] crypto: add support for TLS 1.0 record encryption
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch adds kernel support for encryption/decryption of TLS 1.0
+records using block ciphers. Implementation is similar to authenc in the
+sense that the base algorithms (AES, SHA1) are combined in a template to
+produce TLS encapsulation frames. The composite algorithm will be called
+"tls10(hmac(<digest>),cbc(<cipher>))". The cipher and hmac keys are
+wrapped in the same format used by authenc.c.

++ Support for TLS 1.0 record encryption and decryption
++
++ This module adds support for encryption/decryption of TLS 1.0 frames
++ using blockcipher algorithms. The name of the resulting algorithm is
++ "tls10(hmac(<digest>),cbc(<cipher>))". By default, the generic base
++ algorithms are used (e.g. aes-generic, sha1-generic), but hardware
++ accelerated versions will be used automatically if available.
++
++ User-space applications (OpenSSL, GnuTLS) can offload TLS 1.0
++ operations through AF_ALG or cryptodev interfaces
