Installation

$ composer require violuke/rsa-ssh-key-fingerprint

Usage (default MD5 fingerprint)

$key = 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDHbry1PSM+P0eQZX32b8Gy/cAkxktpzB0hVPnvLDAqUGA2k7e4MJz7V4jYpNqeWUMqElKSAgn/GYwra7U2YpA/eZWSPpWIL2pwy4oQ2+bRaSzlt6wyB4aTLG1dHRFl+kYK3dN3XDdjY2Fx+xQX809eeWtmqBWy5khbQ2Fx0ovK6f0mSbtJRMrLioBYQ/2YQXeR5HQH8CjLZHJ8XeY4BjJ0D+W0yRim+uD7d3CqCUlR2BVDi0MevVMnvwefKQD9cJMOJSsHdGP8Vm/PMpZ5tS4JSTULVkBHfzpC/2D7AI4jbAxUO9j7kChaRY+te+6mYLJGkUtgMDOrTNTaOEAKjeO/ lukecousins@Lukes-iMac.local'; $fingerprint = violuke\RsaSshKeyFingerprint\FingerprintGenerator::getFingerprint($key); echo $fingerprint;
