HP Open Source Security for OpenVMS, Volume 2

This document serves as a comprehensive guide for application developers to utilize OpenSSL's security capabilities within HP OpenVMS I64, Alpha, and VAX environments, specifically focusing on HP SSL for OpenVMS Version 1.3.

The manual begins with installation instructions and release notes, outlining hardware and software prerequisites, new features in version 1.3 (like automatic installation with OpenVMS V8.3), post-installation tasks, the HP SSL directory structure, and guidance on building applications with 64-bit and 32-bit APIs. It also includes important legal cautions regarding cryptographic algorithms.

A significant part of the document provides an overview of the Secure Sockets Layer (SSL) protocol, detailing its components such as the SSL handshake, public key encryption, certificates, cipher suites, and digital signatures. It then introduces the Certificate Tool, a menu-driven utility for managing SSL certificates (viewing, creating, signing, and revoking).

For developers, a programming tutorial on using OpenSSL APIs is included, covering SSL data structures, certificate configuration for SSL applications, and steps for initializing, setting up, connecting, transmitting data, and closing SSL connections. The document also provides example programs. Lastly, it offers an extensive reference for the OpenSSL Command Line Interface (CLI) and CRYPTO/SSL Application Programming Interfaces, detailing commands for creating key parameters, X.509 certificates, CRLs, message digests, ciphers, and handling S/MIME mail.
