The collection of sample code here demonstrates how NSS can be used for cryptographic operations, certificate handling, SSL, etc. It also demonstrates some best practices in the application of cryptography.
Old samples in the process of being replaced.
These are very old examples in need of replacement. See https://bugzilla.mozilla.org/show_bug.cgi?id=490238
