SSH Fingerprint (for node.js)
A minimal library to read an SSH public key (id_rsa.pub)
and generate its fingerprint.
Works for RSA and ECDSA public keys.
Features
< 100 lines of code | <1kb gzipped | 1.8kb minified | 3.1kb with comments
- SSH Public Key SHA256 Fingerprints
- RSA (2048-bit, 3072-bit, 4096-bit)
- EC / ECDSA
- P-256 (prime256v1, secp256r1)
- P-384 (secp384r1)
- Browser Version
CLI
You can install ssh-fingerprint and use it from command line:
npm install -g ssh-fingerprint
ssh-fingerprint ~/.ssh/id_rsa.pub
2048 SHA256:yCB62vBVsOwqksgYwy/WDbaMF2PhPijAwcrlzmrxfko root@localhost (RSA)
(the output is the same as ssh-keygen -lf ~/.ssh/id_rsa.pub)
Usage
You can also use it from JavaScript:
SSH Fingerprint
var fs = require('fs');
var SSH = require('ssh-fingerprint');
var pub = fs.readFileSync("./id_rsa.pub");
SSH.fingerprint({ pub: pub }).then(function (fing) {
console.info('The key fingerprint is:');
console.info(fing.fingerprint, fing.comment);
// SHA256:yCB62vBVsOwqksgYwy/WDbaMF2PhPijAwcrlzmrxfko root@localhost
});
