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

The ROT13 Cipher strategy effectively probes scenarios involving basic obfuscation and information hiding. It is particularly useful in environments where attackers may attempt to obscure their communications or data from casual observers, but where stronger encryption is not employed.
