Find weak spots in symmetric encryption.
Guides plaintext and key recovery from symmetric-encryption weaknesses in CTFs and authorized testing.
When to use it
Use for block-cipher mode weaknesses, stream-cipher key reuse, or meet-in-the-middle attacks.
Give it a symmetric-cipher challenge; it provides attack selection, walkthroughs, and implementation examples.
No setup requirements listed.
