I want to get a SSH key for gitlab for uploading my project. But for creating a key that command line doesn't work

Question

Here is the screen capture for the problem:

In command-line(CMD):

> ssh-keygen -t rsa -C "..."
'ssh-keygen' is not recognized as an internal or external program.

How to generate ssh key? How can I use ssh-keygen?

Answer 1

Consider using Git for Windows, with a simplified PATH and a portable Git (like PortableGit-2.21.0-64-bit.7z.exe), uncompressed anywhere you want.

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%

In that CMD (run as a regular user, not admin), you should have ssh-keygen available.

Example for me:

vonc@VONC D:\
> where ssh-keygen
D:\prgs\git\latest\usr\bin\ssh-keygen.exe

But, due to a recent openssh change, use:

ssh-keygen -m PEM -t rsa -P "" -f afile

You will have a key compatible with classic PEM listeners.
