ChangeExpirationDate Method

Changes the expiration date of the key.

Syntax

ANSI (Cross Platform)
int ChangeExpirationDate(int iExpirationDate);

Unicode (Windows)
INT ChangeExpirationDate(INT iExpirationDate);
- (void)changeExpirationDate:(int)expirationDate;
#define MID_KEYMGR_CHANGEEXPIRATIONDATE 4

IPWORKSENCRYPT_EXTERNAL int IPWORKSENCRYPT_CALL IPWorksEncrypt_KeyMgr_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

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 (C++)

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.)
