EncryptingAlgorithm Property

Textual description of the encrypting algorithm.

Syntax

 smime.getEncryptingAlgorithm([callback])
 smime.setEncryptingAlgorithm( encryptingAlgorithm, [callback])

Default Value

"3DES"

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 getEncryptingAlgorithm([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 setEncryptingAlgorithm([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

This property contains either the name of the algorithm (such as "RC2", "3DES", "DES", or "AES"), or an object identifier (OID) string representing the algorithm.

In the case of "RC2" ("RC2CBC") the key bit length is specified after the name. The following algorithm names are supported for RC2: "RC2CBC40", "RC2CBC64", and "RC2CBC128", with the default being 128 bit ("RC2CBC128").

RC2 is not supported in the Java edition.

In the case of "AES" ("AESCBC") the key bit length is specified after the name. The following algorithm names are supported for AES: "AESCBC128", "AESCBC192", and "AESCBC256", with the default being 128 bit ("AESCBC128").

When read, the value of the property always contains the OID of the algorithm, or an empty string if the algorithm is unknown.
