Run the command bellow only if you need to generate a PEM file that contains a chain of both the key store and the public key in one file. 7 Responses to “Generating self-signed SSL certificate using OpenSSL”. Opensslsign computes a signature for the specified data by generating a cryptographic digital signature using the private key associated with privkeyid. Note that the data itself is not encrypted. Opensslsign computes a signature for the specified data by generating a cryptographic digital signature using the private key associated with privkeyid.Note that the data itself is not encrypted. Execute command: 'openssl rsa -text -in privatekey.pem' All parts of privatekey.pem are printed to the screen. This includes the modulus (also referred to as public key and n), public exponent (also referred to as e and exponent; default value is 0x010001), private exponent, and primes used to create keys (prime1, also called p, and prime2. 2014-11-12 10:49 UTC johannes@php.net I agree we have to export that option from stream layer somehow, this needs a good interface. As a work-around you should be able to add your own key to your system's key storage.
I've been banging my head against my cube for a while on this one, and finally gave into the fact that I couldn't get SHA1withDSA signing in PHP to work. In Java, SHA1withDSA signing appears to be a no-brainer. However, in PHP, it's a disaster and I don't fully understand why. Key word generator based on my website. Bottom line, I finally decided to give up on DSA and started using SHA1withRSA to digitally sign a request in PHP. I need to do this because I have a PHP web-app that is communicating with a REST interface which requires each request to be digitally signed. The whole point of the digital signature is so that the REST API can validate that the request really is coming from the sender; in other words, the sender really is who they say they are.
Here's how I got SHA1withRSA digital signing working in PHP.
First, you need to create a public/private key pair. So, use the openssl command to generate a new RSA key:
A PEM encoded key is actually a DER encoded key in base64 format with a header. In Java, if you give someone a PEM key, they have to parse out the header and then base64 un-encode the key to get the bytes which can be a pain. Finally, use PHP to generate a signature that will be used to digitally sign the request. In this example below, the.

Second, now that you have an RSA key you'll need to generate the public piece of the key which will be given to your partner (the person/interface you're sending the signed request to so they can validate your signature):
Note that my public key is DER encoded (-outform DER). Normally, you might generate a PEM encoded key, but a DER encoded key is slightly easier to handle in Java. A PEM encoded key is actually a DER encoded key in base64 format with a header. In Java, if you give someone a PEM key, they have to parse out the header and then base64 un-encode the key to get the bytes which can be a pain.

Finally, use PHP to generate a signature that will be used to digitally sign the request. In this example below, the data I need to sign is stored in the variable $toSign. Typically, $toSign might contain a URL of the request, and some type of API key:
This was tested on RHEL4 U7, with PHP version 4.3.9. I'm sure it will work on PHP 5+, but I haven't tried it.
Good luck.
