Decrypt given data previously encoded with id-smime-alg-CMS3DESwrap cipher algo. Triple DES used for key wrapping in S/MIME (Secure/Multipurpose Internet Mail Extensions), ensuring secure key transport. This algorithm is used in S/MIME for securely wrapping encryption keys, providing a secure way to encrypt email messages. Triple DES (3DES) is less secure than AES and has been largely replaced by more modern algorithms, but it is still secure for key wrapping. 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.
