openssl-toolkit

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-1.1.0.zip or see below for one-liner download, extract, launch:

echo https://github.com/tdharris/openssl-toolkit/releases/download/1.1.0/openssl-toolkit-1.1.0.zip \
| xargs wget -qO- -O tmp.zip && unzip -o tmp.zip && rm tmp.zip && ./openssl-toolkit/openssl-toolkit.sh

The following tasks are supported:

1. Create certificates:

   • Self-Signed SSL Certificate (key, csr, crt)
   • Private Key & Certificate Signing Request (key, csr)
   • PEM from previous certificates (key, crt, intermediate crts)

2. Convert certificates:

• PEM -> DER
• PEM -> P7B
• PEM -> PFX
• DER -> PEM
• P7B -> PEM
• P7B -> PFX
• PFX -> PEM

3. Verify certificates:

• CSR is signed by private key
• Public certificate and private key are a keypair
• 3rd party intermediate chain file and signed public certificate are a keypair
• Check date validity of certificates

4. Test ssl server:

• SSL Certificate handshake
• SSL Server date validity
• Permitted Protocols

5. Output certificate information:

• Output the details from a certifticate sign request
• Output the details from a signed certificate
