What is the challenge password in a CSR?

The “challenge password” is basically a shared-secret nonce between you and the SSL certificate-issuer (aka Certification Authority, or CA), embedded in the CSR, which the issuer may use to authenticate you should that ever be needed.

How do I recover my CSR private key?

If you have a Private key but not sure it matches the certificate you received from the Certificate Authority, just go here to check. In case the RSA Key was deleted from the server and there is no way to restore it, the Reissue is the only way out. You will need to have a new pair of CSR code/RSA Key generated.

What is a CSR passphrase?

It’s called ‘passphrase’ and it is used to encrypt your private key. If the passphrase is lost, you will have to either reissue your certificate or purchase a new one. If you are using a CSR challenge password for your certificate, you need to make sure it contains only alphanumeric characters.

Do you need a private key to generate a CSR?

In order for a CSR to be created, it needs to have a private key from which the public key is extracted. This can be done by using an existing private key or generating a new private key.

What is PEM password?

A passphrase is a word or phrase that protects private key files. It prevents unauthorized users from encrypting them. The first time you’re asked for a PEM pass-phrase, you should enter the old pass-phrase. After that, you’ll be asked again to enter a pass-phrase – this time, use the new pass-phrase.

What does a CSR look like?

What does a CSR look like? The CSR itself is usually created in a Base-64 based PEM format. You can open the CSR file using a simple text editor and it will look like the sample below. You must include the header and footer (—–BEGIN NEW CERTIFICATE REQUEST—–) when pasting the CSR.

Can a CSR file be used for daily operations?

Only in the CSR. And you don’t need the CSR for daily operations, so presumably operations personnel might not come into contact with the CSR file and therefore not know the Challenge Password .) (But bear in mind that you still have to worry about a rogue admin who has your cert/key. A lot.

When do I need a challenge password for SSL?

1 Answer 1. The “challenge password” requested as part of the CSR generation, is different from the passphrase used to encrypt the secret key (requested at key generation time, or when a plaintext key is later encrypted – and then requested again each time the SSL-enabled service that uses it starts up).

Is the challenge password the same as the passphrase?

So I say again: the “challenge password” requested as part of the CSR generation is not the same thing as a passphrase used to encrypt the secret key.

What’s the use of challenge password in build?

If you have a rogue admin who has access to the cert and key then that admin could revoke the cert and DOS you. But if you have a CA that will challenge the rogue admin to supply the “Challenge Password”, then the rogue admin may not have that password and then you’re safe from that DOS.
