Encrypt given data using camellia-128-cfb1 cipher algo. Camellia in 128-bit key size with CFB1 mode, encrypting 1 bit at a time using a feedback loop, ideal for low-latency environments. Part of Camellia's broad suite of modes, developed by Mitsubishi Electric and NTT in the 2000s. Camellia-128-CFB1 is secure and considered a reliable option for stream encryption, though it is rarely used outside of specific use cases. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
