Decrypt given data previously encoded with aes-128-cfb1 cipher algo. AES-128-CFB with 1-bit feedback size. A variant of CFB designed for bit-level encryption. Not commonly used due to inefficiency and susceptibility to attacks on short feedback sizes. Our decryption process assumes the IV string is prepended in the encoded string during the encryption process. You can not decrypt and get the correct results if the IV or passphrase mismatch occurs between encryption and decryption process.
