Package net.i2p.crypto.eddsa.math.ed25519 Description

High-performance, optimized mathematical implementation for Ed25519 using Radix 2^51 representation.

This package provides a low-level, highly optimized implementation of the mathematical operations required for Ed25519 signatures on Curve25519. The implementation uses Radix 2^51 representation for maximum performance on modern processors.

Key Features:

• Performance Optimization: Radix 2^51 representation for efficient arithmetic
• Curve25519 Support: Specialized implementation for Ed25519 curve
• Field Operations: Optimized finite field arithmetic
• Group Operations: Fast elliptic curve point operations

Components:

• Field Elements: Optimized representation and operations
• Group Elements: Efficient curve point arithmetic
• Scalar Operations: Fast scalar multiplication and addition

This implementation is significantly faster than the generic BigInteger-based approach and is used by default for Ed25519 operations in I2P. For other curves, see the bigint implementation.
