Hi Daniel Gustafsson and Vladyslav Nebozhyn,
I created a patch for CFB mode for AES encryption. Please have a look
and let me know what you think.
Patch covers implementation, tests and documentation changes.
OpenSSL profives aes-cfb1, aes-cfb8 and aes-cfb128 modes where aes-cfb
defaults to aes-cfb128. For simplicity I only added aes-cfb, which is
the most common method used, lower number of bits will introduce
performance degradation, but if it's desirable I can add them as well.
