This is an OpenSSL certificate toolkit utility leveraging OpenSSL's CLI for Linux. This is a simple wrapper utility for OpenSSL CLI to help automate certificate tasks.

Download openssl-toolkit.zip or see below for one-liner download, extract, launch:

echo https://github.com/tdharris/openssl-toolkit/releases/download/1.0/openssl-toolkit.zip | xargs wget -qO- -O tmp.zip && unzip tmp.zip && rm tmp.zip && ./openssl-toolkit.sh

Please report any issues or enhancement requests to OpenSSL-Toolkit on GitHub.

See below for a list of supported features:

1. 1. Create certificates:
      
      
      • • Self-Signed SSL Certificate (key, csr, crt)
      
      
      • • Private Key & Certificate Signing Request (key, csr)
      
      
      • • PEM with key and entire trust chain
      
      
      

1. 1. Convert certificates:
      
      
      • • PEM -> DER
      
      
      • • PEM -> P7B
      
      
      • • PEM -> PFX
      
      
      • • DER -> PEM
      
      
      • • P7B -> PEM
      
      
      • • P7B -> PFX
      
      
      • • PFX -> PEM
      
      
      

1. 1. Verify certificates:
      
      
      • • CSR is a public key from the private key
      
      
      • • Signed certificate is the public key from the private key
      
      
      • • Chain file applies to the signed certificate (complete ssl chain)
      
      
      • • Check date validity of certificates
      
      
      

1. 1. Test ssl server:
      
      
      • • SSL Certificate handshake
      
      
      • • SSL Server date validity
      
      
      • • Permitted Protocols
      
      
      

1. 1. Output certificate information:
      
      
      • • Output the details from a certifticate sign request
      
      
      • • Output the details from a signed certificate
