Encrypt given data using camellia-128-ctr cipher algo. Camellia in 128-bit key size with CTR (Counter) mode, a mode that turns the block cipher into a stream cipher by generating key streams. Camellia was developed by Mitsubishi Electric and NTT in the early 2000s, and CTR mode is used for parallelizable and high-speed encryption. Camellia-128-CTR is considered secure and fast, often used in high-performance systems for its efficiency and ability to parallelize encryption. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
