Cryptography VA Smalltalk provides a rich set of cryptographic primitives useful for securing many forms of digital communications.These are the same primitives brought together to implement protocols such as SSL/TLS. This chapter describes VA Smalltalk's cryptographic support in the following manner: • Provide an introduction to cryptography in VA Smalltalk • How to use the cryptographic feature in a running image. • High-Level Architectural Overview • Low-Level Module Overview with relevant APIs and Examples
