Encrypt given data using camellia-192-cfb cipher algo. Camellia in 192-bit key size with CFB mode, providing stream encryption for variable-length data. Developed in the 2000s by Mitsubishi Electric and NTT, Camellia supports various modes for flexibility in encryption schemes. Camellia-192-CFB is considered very secure and widely trusted in cryptographic applications. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
