E-mail Signature Checking

[This is preliminary documentation and subject to change.]

The workflow engine validates electronic signatures and certificates on incoming emails during an OnReceive event. The engine sets the IsAuthenticated, IsIntact, IsSigned, and IsTrustedSig properties of the IWorkflowSession interface. The property is a set of flags that informs your script of the following potential problems:

• Message is not signed
• Signature verification failed
• Message tampered with
• Certificate not trusted
• Signer address doesn't match Sender address

You can write your condition script for the OnReceive event in the ActionTable to check these flags and take appropriate action.
