Keygen

Generate keypairs for use in other applications. The repository contains generators for the following cryptosystems:

• ed25519
• secp256k1

Build

cargo build --release

Reproducible builds

Reproducible builds can be done using a Rust Docker image to standardize the build environment:

# For amd64
docker run --rm -v `pwd`:/code rust@sha256:ed7795c6eaccae53be35939e883e8c3de0197b21e8eddbd9f04b0c4bc757c094 /code/build-amd64.sh

# For arm64
docker run --rm -v `pwd`:/code rust@sha256:c428882ff081342a9661fb13a1d059ecdc0b6e979ffec64b80371cf20a2088b0 /code/build-arm64.sh

The prebuilt binaries are then compressed using upx version 4.2.4. Expected sha256 checksums are available along with the links to the prebuilt binaries.

Usage

$ ./target/release/keygen-ed25519 --help
Usage: keygen-ed25519 --secret <SECRET> --public <PUBLIC>

Options:
  -s, --secret <SECRET>  path to private key file
  -p, --public <PUBLIC>  path to public key file
  -h, --help             Print help
  -V, --version          Print version

Example

keygen-ed25519 generates a ed25519 key pair and stores it in the file paths provided. The secret key and public key are stored as bytes, with a size of 64 and 32 respectively.

$ ./target/release/keygen-ed25519 --secret ed25519.sec --public ed25519.pub
