I have accidentally become the unofficial apt repo for Step CLI. I've been ruining it for years and just expanded it to include the ARM64 package (e.g. for raspberry pi boards)

For those not familiar, step allows you to:

- run your own certificate authority

- get x.509 certs (TLS)

- sign SSH host key (no more manual fingerprint verification!)

- sign SSH user certs (no more manually copying around keys in authorized_keys)

- and lots more cryptography stuff

It's pretty great.
