Decrypt given data previously encoded with des-ede3-ofb cipher algo. Triple DES (DES-EDE3) in OFB (Output Feedback) mode, converting the block cipher into a stream cipher by using a feedback loop. OFB mode with Triple DES was introduced to handle streams of data efficiently, providing a secure method for encrypting smaller chunks. Triple DES (EDE3) in OFB mode is more secure than ECB but still suffers from performance issues and is considered outdated compared to newer algorithms. 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.
