- net.i2p.crypto.eddsa.math.bigint.BigIntegerScalarOps

All Implemented Interfaces:
Serializable, ScalarOps
```
public class BigIntegerScalarOps
extends Object
implements ScalarOps
```
BigInteger-based implementation of scalar operations for EdDSA cryptography. This class provides fundamental scalar arithmetic operations required for EdDSA signature schemes, including modular reduction and scalar multiplication with addition. All operations are performed modulo the subgroup order l, ensuring results remain within the valid scalar range for EdDSA operations.
