Decrypt given data previously encoded with camellia-192-ofb cipher algo. Camellia in 192-bit key size with OFB mode, a secure mode that turns the block cipher into a stream cipher. OFB mode was designed to address the weaknesses of ECB while retaining the benefits of block ciphers. OFB is secure but may still suffer from error propagation and key reuse vulnerabilities. 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.
