KeyFileCRC Property

The CRC-16 checksum of the EMV public key.

Syntax

 emvkeymgr.getKeyFileCRC([callback])
 emvkeymgr.setKeyFileCRC( keyFileCRC, [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 getKeyFileCRC([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 setKeyFileCRC([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 4 character CRC-16 checksum of the EMV public key. This is a hexadecimal value representation of two bytes, for instance "AA02".

This property should be set to the checksum of the current public key before calling CheckForUpdate. If no previous key has been downloaded leave this setting empty.

This property will be populated with values returned by the server after calling CheckForUpdate or GetKeyInfo.

This property is only applicable when Platform is set to FDMS Rapid Connect.
