Decrypt given data previously encoded with camellia-256-cfb cipher algo. Camellia in 256-bit key size with CFB mode, providing secure stream encryption for variable-length data. Developed to offer flexible encryption schemes, Camellia in 256-bit mode with CFB is part of the Camellia family's suite of secure modes. Camellia-256-CFB is highly secure and offers robust protection against modern cryptographic attacks. 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.
