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

Generic mathematical implementation using Java BigIntegers for arbitrary elliptic curves.

This package provides a low-level, non-optimized implementation of elliptic curve mathematical operations using Java's built-in BigInteger class. The implementation is designed to work with any elliptic curve, making it suitable for testing, compatibility, or curves without specialized optimizations.

Characteristics:

• Generic Support: Works with any elliptic curve parameters
• BigInteger Based: Uses standard Java BigInteger arithmetic
• Reference Implementation: Clear, readable mathematical operations
• Compatibility: Ensures correctness across different curve types

Usage:

• Testing and verification of optimized implementations
• Support for non-standard curves
• Educational purposes and algorithm understanding
• Fallback implementation when optimizations are unavailable

Note: This implementation is currently unused in production I2P code. For Curve25519 operations, the optimized ed25519 implementation provides significantly better performance.
