I am learning this post, whose title is "Checking for existing SSH keys".
Checking for existing SSH keys
Before you generate an SSH key, you can check to see if you have any existing SSH keys.
Note: DSA keys were deprecated in OpenSSH 7.0. If your operating system uses OpenSSH, you'll need to use an alternate type of key when setting up SSH, such as an RSA key. For instance, if your operating system is MacOS Sierra, you can set up SSH using an RSA key.
Is it grammatical, idiomatic and clear if I simplify that to "Check existing SSH keys"?
