Key Property
The symmetric key to use for decryption.
Syntax
messagedecryptor.getKey([callback]) messagedecryptor.setKey( key_Buffer, [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 the getKey([callback]) method is defined as:
function(err, buffer){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'buffer' is the value returned by the method.
The callback for the setKey([callback]) 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
Use this property to provide the symmetric key to decrypt the data. This property is only applicable for processing data of EncryptedData subtype.
Assign this property before calling Decrypt.
This property is not available at design time.
