Class Summary
Class	Description

BigIntegerLittleEndianEncoding	Little-endian encoding of field elements for EdDSA, backed by BigInteger.
BigIntegerScalarOps	BigInteger-based implementation of scalar operations for EdDSA cryptography.

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.
