ChangeExpirationDate Method

Changes the expiration date of the key.

Syntax

int ChangeExpirationDate(int iExpirationDate);

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.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
