Set permission of file equivalent to chmod 400 on Windows.

chmod-400.cmd

# Source: https://stackoverflow.com/a/43317244
$path = ".\aws-ec2-key.pem"
# Reset to remove explict permissions
icacls.exe $path /reset
# Give current user explicit read-permission
icacls.exe $path /GRANT:R "$($env:USERNAME):(R)"
# Disable inheritance and remove inherited permissions
icacls.exe $path /inheritance:r

In windows 10, using the commands listed above I ran into the following error:

Invalid parameter "$($env:username):(r)"

so, I changed it by "%username%:(r)" and it worked properly. Thanks a lot!!!

Thanks...You saved the day!

keep in mind that although both of these solutions perfectly work but itll still have owner group and other read permissions if sshing via wsl and might still give bad permisiions. so you need to ssh explicitly via powershell not wsl

This works Thanks alot
