FOSSA Status

This tool can be used to sign, verify, generate a keypair with ed25519 (both sha2 and sha3).

1. build and install

  1. build ed25519

    git clone https://github.com/hyperledger/iroha-ed25519
cd iroha-ed25519
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD=STATIC -DHASH=sha3_brainhub
sudo make install

    Note: this will install libed25519 with SHA3. If you need sha2 variant, then change sha3_brainhub to sha2_openssl.

  2. build ed25519-cli

    git clone https://github.com/Warchant/ed25519-cli
cd ed25519-cli
git submodule update --init
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
sudo make install

    Binary ed25519-cli will be installed.

2. use

./ed25519-cli --help                                                                                                                        bogdan@Bogdans-MacBook-Pro
