How to check if an RSA public / private key pair match

[dil_bert]

I have two files, id_rsa and id_rsa.pub. What command can be used to validate if they are a valid pair?

i have tested this way:

ssh-keygen -y -e -f <private key>


[martin@martin-pc ~]$ ssh-keygen -y -e -f <private key>
bash: Syntaxfehler beim unerwarteten Wort `newline'
[martin@martin-pc ~]$

why do i get this error ?!

I can only assume the problem is that you don't know what "unexpected token" means. Frankly, I'm not sure what it's doing there either.

ssh-keygen -ye with the private key will tell you the public key. Compare the output with your actual public key to see if they match.
