smime.decrypt([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 takes the Message property and attempts to decrypt the encrypted PKCS envelope using the certificate in Certificate. If the class is able to decrypt it will replace Message and MessageHeaders with the decrypted text.
