VerifySignature Method

Verifies the signature of the current Message .

Syntax

smime.verifySignature([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method attempts to verify the signature contained in Message. If the message does not have a certificate attached, the class will attempt to verify the signature using the certificate supplied in SignerCert (if any). If no certificate is found, the class fails with an error.

If this method is successful, the SignerCert property will contain the certificate information of the message signer.

NOTE: This function does not attempt to check the validity of the signing certificate itself.
