How do I verify that a private key matches a certificate?
To verify that an RSA private key matches the RSA public key in a certificate you need to i) verify the consistency of the private key and ii) compare the modulus of the public key in the certificate against the modulus of the private key.
Public and private key pairs lie at the core of how is referred to as public key cryptography. Together, they work to secure and authenticate messages. They also lie behind how we authenticate messages at PreVeil. We often find ourselves explaining the concepts of how these keys work when we talk to prospective clients. Matching a private key to a public key. If you do much work with SSL or SSH, you spend a lot of time wrangling certificates and public keys. Public key cryptography provides the underpinnings of the PKI trust infrastructure that the modern internet relies on, and key management is a big part of making that infrastructure work.

Worked like a charm as soon as I integrated the whole chain into a PFX. That was the first time that I attempted this. I'll be testing and documenting this over the next week for my team but, so far, the PFX file looks to be a lot simpler than other methods. Check whether a private key matches a certificate or whether a certificate matches private key, check whether a csr matches a certificate matches private key openssl certificate check, x509 certificate tutorial. Create Your Public/Private Key Pair. Use gpg -full-gen-key command to generate your key pair. Gpg -full-gen-key. It will ask you what kind of key you want. Notice that there are four options. The default is to create a RSA public/private key pair and also a RSA signing key.

To verify the consistency of the RSA private key and to view its modulus:
openssl rsa -modulus -noout -in myserver.key openssl md5
openssl rsa -check -noout -in myserver.key openssl md5
RSA Key is ok
If it doesn't say 'RSA key ok', it isn't OK!'

If the first commands shows any errors, or if the modulus of the public key in the certificate and the modulus of the private key do not exactly match, then you're not using the correct private key. You can either create a brand new key and CSR and contact support, or you can do a search for any other private keys on the system and see if they match.
How Generate A Private Key That Matches A Public Key Location
To search for all private keys on your server:
find / -name *.key
If you are unable to find the private key that corresponds to your certificate, you will need a replacement certificate. Please contact support.
