ERR_OSSL_X509_KEY_VALUES_MISMATCH

[Utopia-FinTech]

Hi,

I just get started with the visa SDK for node js. I followed the instruction on the README file correctly but I just keep getting this response.

error {"library":"x509 certificate routines","function":"X509_check_private_key","reason":"key values mismatch","code":"ERR_OSSL_X509_KEY_VALUES_MISMATCH"}

Any help is appreciated. 

Thank you.

Hi @Utopia-FinTech and @Bhawani,

First off, you get this error if the private key you've specified does not match the public key in the certificate you are trying to use. Please check that the private key you use matches the public key in the certificate. This can be done be comparing the output of the following commands which should be the same:

openssl x509 -noout -modulus -in your-cert-file.pem
openssl rsa -noout -modulus -in your-key-file.pem

If these do not match, then perhaps you have used the wrong file for either your cert or your key files.

cert => file you download from the Credentials section of the Portal
key ==> the private key that you downloaded or created when you first created the project
ca ==> on a Mac, you can point to cacerts (if you get a self-signed error, see if commenting this out helps)

This worked on NodeJS v 14.15.0 and 15.1.0 (npm 6.14.8, 7.0.8)
