Scheme Property
The algorithm scheme to use.
Syntax
publickeycrypto.getScheme([callback]) publickeycrypto.setScheme( scheme, [callback])
Default Value
""
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 getScheme([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 setScheme([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
Certain asymmetric algorithms are often accompanied with a specific algorithm scheme. Two typical examples are RSA's own OAEP and PSS schemes. Use this property to tune up the scheme to use. Leave it empty to proceed with the standard scheme (such as PKCS#1-v1.5 for RSA).Supported schemes:
RSA: PKCS#1, PSS, OAEP, SSL3
ECDSA: ed25519, ed448, ed25519ph, ed448ph
