Easy-RSA is a command-line utility for creating and managing a public key infrastructure with OpenSSL. It provides a more convenient layer around common certificate authority operations while retaining a straightforward file-based approach to keys, certificates and PKI data.
The software can be used to establish a private certificate authority for servers, clients, VPN infrastructure and other systems requiring locally issued X.509 certificates. Although Easy-RSA is developed alongside OpenVPN, it is a separate project and is not restricted to OpenVPN deployments.
Its command-line approach makes it well suited to systems without a graphical environment and to administrators who want certificate-management procedures that can be documented or incorporated into scripts.
Easy-RSA deliberately concentrates on the core tasks involved in operating a certificate authority. It does not try to provide the web interfaces, workflow engines or distributed services found in enterprise PKI suites. This keeps the software relatively lightweight and gives administrators direct access to the files and structures underpinning their certificate authority.
The utility is particularly useful where OpenSSL provides the required cryptographic functionality but its lower-level commands would make routine CA administration unnecessarily cumbersome.
This is free and open source software.
