If you use very strong SSH/SFTP passwords, your accounts are already safe from brute force attacks. You’re looking for a pair of files named something like id_dsa or id_rsa and a matching file with a .pub extension. You can generate the SSH Key in a convenient location, such as the computer, and then upload the public key to the SSH key section. When the two match up, the system unlocks without the need for a password. The main problem here is, that SSH assumes that you have an RSA key set and uses it if one was found. Install … Give password. There are different encryption algorithms. The PuTTY keygen tool offers several other algorithms – DSA, ECDSA, Ed25519, and SSH-1 (RSA)..

Assuming your private SSH key is named ~/.ssh/id_rsa, add following to the config file: Host github.com HostName github.com User git IdentityFile ~/.ssh/id_rsa IdentitiesOnly yes. Opcional.
