Make your visual drawings or use the generator in coin mode just fllipping the coin and fill the corresponding cell depending on the coin outcome. Note: Click Generate to generate a public/private key pair. From the private key, we use elliptic curve multiplication, a one-way cryptographic function, to generate a public key (K). $ ssh-add -K ~/.ssh/id_ed25519 If you don’t have these files (or you don’t even have a .ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS systems and … Public key authentication.
