SSH “Vanity” Key Generator

What is this?

Type something consisting of base64 characters into the “Embedded Text” field, then click “Submit”. An SSH keypair will be generated, and the public key will contain your text.

How does it work?

MagicIt’s using basically the same algorithm described in my Stupid Certificate Tricks post, with some minor tweaks to make sure the data is aligned correctly.

Is it safe?
