YAML config

CLI

bash

# "math-encoding" is layered onto attacks during red-team scans.
# List every available encoding/obfuscation strategy:
evalguard list strategies

Combine with attack plugins to generate adversarial payloads. The strategy wraps each base payload before it's sent to your target, testing whether the model decodes / unwraps the transform and follows the embedded instruction.

Threat-model fit

Math Encoding effectively probes systems that rely on pattern matching and static analysis for input validation. It is particularly useful against systems that do not adequately parse or interpret encoded characters, allowing for potential bypass of security measures.
