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. -- Umar Hayat Bitnine (https://bitnine.net/)
