DSA (Digital Signature Algorithm). A type of code-signing certificate used in
Java 1.2+. It replaces the older
RSA (Rivest, Shamir and Adelman)
certificate used in the proprietary Netscape jar-signing scheme. DSA-signed Applets
refer to the Sun Java version 1.2 jar signing scheme.
Sun-style RSA-signed Applets were introduced Java version 1.3
and have now largely replaced the DSA
scheme. I still use them because Wassup is signed and can run under
Java version 1.2.
