Decrypt given data previously encoded with camellia-256-cbc cipher algo. Camellia in 256-bit key size with CBC mode, providing enhanced security through a larger key size. Camellia supports up to 256-bit key sizes, designed to meet high security requirements in modern cryptographic environments. Camellia-256 is considered highly secure and is a recommended choice for systems requiring high levels of encryption strength. 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.
