Foil 9 Java Security

From Overview of JDK Version 1.1 Extensions CPS616 -- Information Track of CPS -- Spring Semester 97. by Nancy J. McCracken
The first release of the new Java security package has
  • Digital signatures: algorithms such as DSA for generating public/private key pairs, signing and verifying digital data.
  • Message digests: one-way hash algorithms for producing "digital fingerprints" of data, frequently used in digital signatures.
  • Key management: system of managing individual users and groups with keys and certificates.
  • Access control lists: access permissions.
Some of these interfaces are abstract - implementations are provided in "Java Cryptography Extension" (JCE) released separately to JDK "in accordance with U.S. export control regulations".
  • Each JDK can have one or more "Cryptography Package Provider" installed. Default is Sun, but users can install own cryptography package.
