Rsa keygen

[Zacholme7]

Issue Addressed

#154

Proposed Changes

This pr introduces a new cli tool to generate rsa keys. It will generate a key.pem file to be used with the anchor nodes and a keys.json file that contains the base64 encoded keys to be used with the ssv ui webapp.

Note: this replaces the base64 headers in the key so that we can interop with the ssv-client for ssv-mini

Looks good!

What do you think about changing the client to implicitly invoke this if it finds no key? Replacing its current key gen mechanism.

Nice, thanks! Just a nitpick:

Looks good! Another thing that came to my mind is zeroing the memory after use with zeroize. It's a bit complicated to do correctly (as moves might leave unzeroed memory, but clones don't) and it's difficult to reason about invoked library functions, but even doing it on a "best effort" basis would be better than nothing. Do you want to try it? If so, I recommend reading through the main docs page: https://docs.rs/zeroize/latest/zeroize/

[Zacholme7]

Update: Need the ability to be able to force overwrites in ssv-mini so added cli flag to accomplish this

[Zacholme7]

We are writing passwords out in plaintext right now, which kinda defeats the purpose of zeroing out the memory.

Adding an issue to enable password protection for the private key file.

Pull Request Overview

This PR introduces a new CLI tool for RSA key generation to support anchor nodes and the SSV UI webapp by generating a PEM file and a JSON file with base64 encoded keys.

• Added a new Cargo package (keygen) with dependencies for key generation.
• Implemented the key generation functionality in keygen’s library and integrated it into the existing anchor and client command flows.
• Updated related Cargo.toml files and a keysplit utility to support the new keygen module.

nice -- just left a few todo comments so we remember to encrypt
