Verify that Keys Match¶
Use the following command, to test both files. The output of the command will show the 'signature' of both files. When the 'signature' matches, they show the public key and private key are both valid and match.
# ssh-keygen -l -f ~/.ssh/id_rsa
2048 SHA256:REDACTED [email protected] (RSA)
# ssh-keygen -l -f ~/.ssh/id_rsa.pub
