+ 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.
