ContentEncryptionAlgorithm Property
The algorithm used to encrypt the content.
Syntax
jwe.getContentEncryptionAlgorithm([callback]) jwe.setContentEncryptionAlgorithm( contentEncryptionAlgorithm, [callback])
Possible Values
0 (ceaA128CBC_HS256), 1 (ceaA192CBC_HS384), 2 (ceaA256CBC_HS512), 3 (ceaA128GCM), 4 (ceaA192GCM), 5 (ceaA256GCM)
Default Value
0
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 getContentEncryptionAlgorithm([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 setContentEncryptionAlgorithm([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 specifies the algorithm used to encrypt the content.
The following values are supported.
