Decrypt given data previously encoded with camellia-256-cfb1 cipher algo. Camellia in 256-bit key size with CFB1 mode, encrypting 1 bit at a time, ideal for low-latency encryption. Camellia was developed by Mitsubishi Electric and NTT in the early 2000s as a high-security alternative to AES, with CFB1 offering fine-grained stream encryption. Considered secure for specific use cases but rarely used due to its niche application. 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.
