Encrypt given data using camellia-192-cfb8 cipher algo. Camellia in 192-bit key size with CFB8 mode, which encrypts 8 bits at a time, offering flexibility for smaller data units. Part of the broader Camellia suite, Camellia-192-CFB8 offers a combination of security and efficiency for certain use cases. Camellia-192-CFB8 is secure, though it is not as widely used as other modes like CBC or CTR. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
