ARKconcepts Certificate Manager (ARKcert)
This simple command-line app is intended to be used primarily for non-production purposes of creating and maintaining SSL/TLS certificates. It should, in theory, work with both .NET and Mono.
It is capable of creating certificate authorities (CAs) and client/server certificates.
It is also capable of converting between Base64-encoded certificate and key files (*.crt/*.cer and *.key) and PKCS#12 files (*.p12/*.pfx).
The usage documentation is auto-generated at runtime using the Command Line Parser Library. All of the crypto functions are provided by Bouncy Castle.
