Encrypting/Decrypting Winzip attachments

[ID015]

Is there a way to encrypt and decrypt attachments with some code? The winzip attachments are password protected with the same password for a determined amount of time.
Any suggestion? Thank you!

You can extract the files from the zip using VBA if you know the password. You cannot use it to crack the password. 7-Zip has a command line processor that can be accessed from VBA.
