Decrypt given data previously encoded with camellia-128-cfb cipher algo. Camellia in 128-bit key size with CFB (Cipher Feedback) mode, a stream cipher mode that encrypts small units of data. Camellia was created by Mitsubishi Electric and NTT in the early 2000s as a block cipher alternative to AES. Camellia is considered very secure and is widely accepted in cryptographic standards, including in environments requiring high security. 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.
