Dangerous toys: Anything to ed25519 (SSH Keys)

• wireguard-vanity-address

  5 406 0.0 Rust

  generate Wireguard keypairs with a given prefix string

another dangerous toy I particularly enjoy, vanity keys:

https://github.com/warner/wireguard-vanity-address

Although not as dangerous since the entropy of the rng is (mostly?) still there. If I'm doing the handwaving right, it's base64 where each char contains 6 bits, so you reduce the effective keysize to 256-6*$num_chars -- cryptographers tell me how wrong I am :)

• lokey

  A tool that makes it easy to work with and convert between cryptographic key formats

• libsodium

  30 11,910 8.7 C

  A modern, portable, easy to use crypto library.

This article [0] has a good explanation of why clamping is necessary. But the process is very simple, you just generate 256 random bits, clear the three lowest order to avoid small subgroup attacks, then clear the highest order and set the second highest order to avoid side-channel attacks which may occur if an implementation isn’t constant-time. The Libsodium source shows this pretty clearly: [1], lines 18-23.
