public class SMIMESign
extends Sign

Puts a server-side SMIME signature on a message. It is a concrete subclass of Sign, with very few modifications to it, to specialize for SMIME.

Handles the following init parameters (will comment only the differences from AbstractSign):

• <debug>.
• <keyStoreFileName>.
• <keyStorePassword>.
• <keyAlias>.
• <keyAliasPassword>.
• <keyStoreType>.
• <postmasterSigns>. The default is true.
• <rebuildFrom>. The default is true.
• <signerName>.
• <explanationText>. There is a default explanation string template in English, displaying also all the headers of the original message (see getExplanationText()).

Since:

2.3.0
