Risk Level: SAFE
Full Analysis
- [SAFE]: The skill provides standard Python implementations for frequency analysis, index of coincidence calculation, and various classical cipher decryption methods (Caesar, Vigenere, Affine, Hill, etc.). All logic is transparent and focused on the stated cryptanalysis purpose.
- [EXTERNAL_DOWNLOADS]: The skill references several well-known and trusted security tools and services including CyberChef (hosted by GCHQ), quipqiup, and dcode.fr. These are standard industry resources for cryptography challenges.
- [EXTERNAL_DOWNLOADS]: Mentions the installation of established Python security packages such as
xortool,ciphey, andhashidvia standard package managers. These are legitimate tools for automated cipher detection and XOR analysis. - [COMMAND_EXECUTION]: Provides examples of using
xortoolfrom the command line, which is an expected behavior for a technical cryptanalysis playbook.
