DID Controller Keypair
Creating a keypair used to control a DID method
Create a new DID controller keypair using openssl. In this example, we use Ed25519, but other algorithms are also supported (see specification).
Make sure you have openssl & GNU coreutils installed and avalible on command line (e.g.
brew install coreutils
on macOS)openssl genpkey -algorithm ed25519 -outform DER >privkey
openssl pkey -in privkey -pubout -out pubkey -inform DER -outform DER
This creates two files,
pubkey
and privkey
.Depending on the method, the public key is encoded in either
- Base64 URL (
base64url
) - Base58 (
base58
)
There are two ways to install it. If one app doesn't work, try the other one.
# using howbrew
brew install base58
# using cargo (requires rust tooling to be installed)
cargo install bs58-cli
## hint latter works best by symlinking: ln -s source_path target_in_path/base58
Some newer features are only available in the latest version of openssl, version 3. To install it
brew install openssl@3
It is not automatically added to the path as macOS uses LibreSSL. Therefore you can use the absolute path.
/opt/homebrew/opt/openssl@3/bin/openssl
