package net.i2p.crypto.eddsa

Java implementation of EdDSA, a digital signature scheme using a variant of elliptic curve cryptography based on Twisted Edwards curves.

Contains a generic implementation for any curve using BigIntegers, and an optimized implementation for Curve 25519 using Radix 2^51. Used throughout I2P for router and destination signatures.

See also: RFC 8032, Twisted Edwards curves.
