Decrypt given data previously encoded with camellia-128-ofb cipher algo. Camellia in 128-bit key size with OFB (Output Feedback) mode, which turns a block cipher into a stream cipher using a feedback loop. OFB mode for Camellia was designed as a secure alternative to other modes like ECB, making it more resilient to certain types of cryptographic attacks. OFB is generally secure but has limitations in 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.
