SSH Key & Token Generator | iN2 Tools

Generate secure RSA, ECDSA, or Ed25519 SSH key pairs locally, or create high-entropy secret API tokens.

SSH Public & Private Key Pair Generator

Generate SSH public and private key pairs across modern cryptographic algorithms (Ed25519, RSA 2048/4096, ECDSA P-256/P-384). Format keys for OpenSSH and PEM.

SSH Public Key Cryptography Standards

SSH asymmetric cryptography pairs a private key (stored locally with 0600 permissions) and a public key (placed on remote server authorized_keys files).

Algorithm Comparison

  • Ed25519 (Recommended): Edwards-curve Digital Signature Algorithm over Curve25519. Provides high performance and resistance to side-channel attacks with a compact 68-character public key.
  • RSA 4096-bit: Standard legacy public-key algorithm offering high compatibility across older systems.
  • ECDSA (P-256 / P-384): Elliptic Curve Digital Signature Algorithm using NIST curves.
