Decrypt given data previously encoded with camellia-256-cfb8 cipher algo. Camellia in 256-bit key size with CFB8 mode, encrypting 8 bits at a time, suitable for smaller data units. Part of the Camellia suite, developed by Mitsubishi Electric and NTT, CFB8 mode enhances flexibility in encryption, though it's less commonly used. Camellia-256-CFB8 is secure but less widely adopted compared to other modes like CBC or CTR. 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.
