Decrypt2

See more MIME Examples

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
