SignatureAlgorithm Property

Signature algorithm to be used in outgoing messages.

Syntax

 as2sender.getSignatureAlgorithm([callback])
 as2sender.setSignatureAlgorithm( signatureAlgorithm, [callback])

Default Value

"sha-256"

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 getSignatureAlgorithm([callback]) method is defined as:

function(err, data){ }

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

'data' is the value returned by the method.

The callback for the setSignatureAlgorithm([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

Signature Algorithm can be set to indicate the preferred signing algorithm. Possible values are:

sha1
md5
sha-256 (or sha256) (default)
sha-384 (or sha384)
sha-512 (or sha512)
sha-224 (or sha224)

The default value is "sha-256". When this property is set the MDNOptions property is automatically updated to request the MDN receipt be signed with the same algorithm.
