Apr 12, 2020  Openssl create self signed certificate with passphrase. In this section I will share the examples to openssl create self signed certificate with passphrase but we will use our encrypted file mypass.enc to create private key and other certificate files. Generate private key. Openssl rsa -in private.pem -outform PEM -pubout -out public.pem. The -pubout flag is really important. Be sure to include it. Next open the public.pem and ensure that it starts with -BEGIN PUBLIC KEY-. This is how you know that this file is the public key of the pair and not a private key. To generate a self-signed SSL certificate using the OpenSSL, complete the following steps: Write down the Common Name (CN) for your SSL Certificate. The CN is the fully qualified name for the system that uses the certificate.

You can use this Certificate Key Matcher to check whether a private key matches a certificate or whether a certificate matches a certificate signing request (CSR). When you are dealing with lots of different certificates it can be easy to lose track of which certificate goes with which private key or which CSR was used to generate which certificate. The Certificate Key Matcher tool makes it easy to determine whether a private key matches or a CSR matches a certificate.

Openssl Generate Public And Private Key Pair

  1. A CSR is a file containing your SSL Certificate application information, including your Public Key. Certificate Auto-Requester: We provides a useful tool to automatically create a public/private key pair on your local machine then use this key pair to generate a CSR and automatically submit it to us over a secure SSL connection to create your certificate for Apache.
  2. Apr 12, 2020  Step 6: Create your own Root CA Certificate. OpenSSL create certificate chain requires Root and Intermediate Certificate. In this step you’ll take the place of VeriSign, Thawte, etc. Use the Root CA key cakey.pem to create a Root CA certificate cacert.pem; Give the root certificate a long expiry date.
  3. Apr 12, 2020 All the commands and steps will remain the same as we used above to generate self signed certificate, the only difference would be that we will not use any encryption method while we create private key in step 1. Openssl generate private key. In this example with openssl genrsa we will not use any encryption.

The Certificate Key Matcher simply compares a hash of the public key from the private key, the certificate, or the CSR and tells you whether they match or not. You can check whether a certificate matches a private key, or a CSR matches a certificate on your own computer by using the OpenSSL commands below:

Openssl Generate Keypair

openssl pkey -in privateKey.key -pubout -outform pem sha256sum
openssl x509 -in certificate.crt -pubkey -noout -outform pem sha256sum
openssl req -in CSR.csr -pubkey -noout -outform pem sha256sum

Your private key is intended to remain on the server. While we try to make this process as secure as possible by using SSL to encrypt the key when it is sent to the server, for complete security, we recommend that you manually check the public key hash of the private key on your server using the OpenSSL commands above.

You can also do a consistency check on the private key if you are worried that it has been tampered with. See Hanno Böck's article How I tricked Symantec with a Fake Private Key for how to do this and when this might be useful.
