Eclipse/Git: "You're using an RSA key with SHA-1, which is no longer allowed. Please use a newer client or a different key type."

Issue

I created a public key in Git using ssh-keygen which was successfully created as .ssh/id_rsa.pub.

I then uploaded it to GitHub in my SSH Keys, and "Authorized" its SSO feature. Everything is uploaded now.

When cloning a repository in Eclipse, I get the following message

Solution

According to Github security blog RSA keys with SHA-1 are no longer accepted.

Use the following command to create new SSH key with ECDSAencryption and add it to Github.

ssh-keygen -t ecdsa -b 521 -C "[email protected]"
