noCA
Copyright © 2007-2025 Michel Messerschmidt
Description
This software can be used to create and maintain Certificate Authorities
(CA) in a Public Key Infrastructure (PKI).
The main goal is to provide a simpler interface than OpenSSL commands,
options and config files while enable access to most public key
functionality (not only RSA key creation).
noCA also supports the PKI operation by providing a customizable directory
structure to keep track of all PKI related files.
noCA is written in Perl and relies on OpenSSL (or a compatible cryptographic
tool) for most of its operations.

System Requirements
- Perl 5.12 (or newer)
- OpenSSL 3.5 (or newer)
(older OpenSSL 3.* versions will work except with the ML-DSA algorithm that is now the default)
(older OpenSSL 1.* versions may still work but are not tested anymore)
(OpenSSL version 0.9.* will not work)
noCA was tested with:
Installation
No installation needed, only extract the files and execute the perl script.
Linux system typically have a perl runtime installed and require no further preparation.
Other systems require installation of a perl distribution.
Basic steps:
- Ensure that perl scripts can be executed and the
openssl command is available
- Create an empty directory and copy the
noCA-*.tar.gz archive into it
- Extract the contents of the
noCA-*.tar.gz archive
- Execute
./noCA.pl init to create the CA directory structure, keys and root certificate
- Execute
./noCA.pl help for more information
