Self-contained Bloom filter implementation for efficient duplicate detection. Uses bit array and multiple hash functions with configurable false positive rate. Demonstrates space-efficient probabilistic data structure design suitable for high-throughput network scanning.

Standalone AES encryption/decryption implementation following FIPS-197 standard. Includes key scheduling, block operations, and lookup tables. Demonstrates correct implementation of a cryptographic primitive with clear separation of concerns and no external dependencies beyond standard libraries.

Implements cyclic group mathematics for generating non-sequential permutations of IP address spaces. Uses GMP for large integer arithmetic to enable efficient, unbiased scanning of large address spaces. Demonstrates non-obvious application of number theory to solve network scanning performance challenges.

Uses AES-RNG to generate and validate packet validation bits to prevent spoofing. Integrates with the probe module system to secure network probes against response injection. Demonstrates a non-obvious technique for securing active network measurements using cryptographic primitives.

Implements a small domain-specific language for filtering scan results. Supports logical operations, comparisons, and field references with proper AST generation and evaluation. Demonstrates parsing and evaluation techniques for flexible output filtering in network scanning tools.
