Module edcert::ed25519

This module contains a wrapper around the libsodium implementation of ed25519. It reduces the size of signatures to 64 byte.

Constants

PRIVATE_KEY_LEN	This is the length of a ed25519 private key.
PUBLIC_KEY_LEN	This is the length of a ed25519 public key.
SIGNATURE_LEN	This is the length of a ed25519 signature.

Functions

generate_keypair	This method generates a random ed25519 keypair from a cryptographically secure source (on unix this is /dev/urandom). Returns (public_key, private_key).
sign	This method takes a data vector and a private key and computes the signature which can be verified using the public key.
verify	This method takes a data vector, a signature and a public key and returns true, if the signature has been created using the correct private key.
