ChangeExpirationDate Method
Changes the expiration date of the key.
Syntax
keymgr.changeExpirationDate(expirationDate, [callback])
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 this 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 method changes the expiration date of the current Key. The ExpirationDate parameter specifies the number of days for which the key is valid starting today. For instance a value of "31" means the key is valid for the next 31 days.
The special value "0" means the key will never expire.
The key's passphrase is required for this operation and may be specified via KeyPassphrase or through the KeyPassphrase event.
Note: See KeyValidityTime for information on specifying the expiration date when creating the key with CreateKey.
