If the SetSslClientCert* method fails, then no client-side certificate has […]
Chilkat supports CAdES-BES and CAdES-EPES digital signatures
Chilkat v9.3.0, being released this week, now supports the ability to create CAdES-BES and CAdES-EPES digital signatures via the MailMan, Mime, and Crypt2 objects.

For CAdES-EPES, […]

Note: “related” items are […]
Cocoa Asynchronous Methods and Event Callbacks
Chilkat v9.3.0 for Cocoa now includes the asynchronous functionality and event callback functionality that has been available in the C++ libs. Asynchronous methods run in a background thread such that the call immediately returns to the application. Events are not fired w/ asynchronous method calls — your app would periodically check to see if the background task is finished. To […]
