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

@audrew thank you!

for windows users use:

icacls.exe your_key_name.pem /reset

icacls.exe your_key_name.pem /grant:r "$($env:username):(r)"

icacls.exe your_key_name.pem /inheritance:r

thats it! your keys.pem have same restrisctions as you use chmod 400

Awesome. Thanks a lot. It worked. Know more at https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-ssh-using-terminal

Thanks

Thank you so much.

I changed it by "%username%:(r)" and it worked properly.

Thanks it worked for me

Somehow following the same steps, I got file permission of 0444, not 0400, and it's not accepted by Azure.

same problem : (

Works !
It doesn't convert it to:
-r--------
but to:
-r--r--r--

Still works for me

If you prefer to do it from UI

• select .pem file -> right click -> properties
• Security > Advanced > Disable inheritance
• Remove all Users
• Add > Select a principal
• In "Enter the object name to select" type your Windows username > ok
• Give all permissions > ok > apply

Doing this, I still have an equivalent of 444 permission in the linux filesystem.

thanks!!

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
