DustinD2 / OpenSSL Verify Signature in Bash

Created December 5, 2012 23:27

This is a sample openssl bash script to create a matching RSA key pair and create a signed sha1 digest of the script itself using the private key. The digest is then verified against the public key.

	#!/bin/bash

	#create our key pairs
	openssl genrsa -out private.pem 2048
	openssl rsa -in private.pem -pubout -out public.pem

	#sign and verify
	openssl dgst -sha1 -sign private.pem -out "$0".sha1 $0
	openssl dgst -sha1 -verify public.pem -signature "$0".sha1 $0
