Decrypt given data previously encoded with aes-192-cfb8 cipher algo. AES with 192-bit key in CFB mode with a feedback size of 8 bits, enabling byte-oriented encryption. A variant of AES-CFB optimized for environments needing byte-level encryption. More secure than CFB1 but still not as widely adopted as other AES modes. 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.
