Check if private key is malformed

  • 772

I've been moving a private key manually via the terminal and I'm getting an error. I suspect this error is caused by malformed key.

Is there a way to check if a key string is correct?

ssh

    You can execute the following commands:

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

    Takes a private key an prints the corresponding public key which can be directly compared to your available public keys. (Hint: beware of comments or key-options)

    You can use also:

    openssl dsa -in <private key> -modulus -noout

    Display the public keys corresponding to a private key, then compare them.
