KeyPlace

• Human friendly key derivation
• Server-assisted + persisted
• Attack resistant
• Use it in WASM or wherever

Why

So, you use paired-key cryptography on the internets, but you're getting fed up with silly humans writing their private keys on cocktail napkins? SAD!

What if I told you there were a way for YOUR server to help manage these keys, but in a not-totally-crappy way?

It slices, it dices:

• Securely derive private keys with no persistant storage on the user's station!
• The server helps, but cannot actually see the keys. If your server gets pwned, you still win!
• You get to change your keys and passwords independently!

But wait, there's more:

• Store multiple keys using that one password
• Store each key using multiple passwords
• You can implement secure key recovery techniques

KeyPlace is inspired by the Keybase key derivation algorithm https://book.keybase.io/docs/crypto

``` use keyplace::{AgentKey,PassKey}; let agentkey = AgentKey::create(None);

let passkey = PassKey::new("I like turtles"); let custkey = agentkey.custodial_key(passkey);

// the custodial key is safe to send to the server // Never send the passkey to anyone!!

let passkey2 = PassKey::new("I like turtles"); let agentkey2 = AgentKey::fromcustodialkey(custkey, passkey2).unwrap(); ```
