WinRAR Signature Scheme in SageMath

I am happy to share with you my work and findings for the popular freeware known as WinRAR😄.

Source Code Organization

• ecc.py : Contains the ECC class, which implements all ellipti-curve related thingies.
• pegwit.py : The main script; this is how you run the scheme.
• prng.py : Contains the PRNG class, which implements WinRAR's pseudo-random number generator.
• scheme.py : Implements WinRAR's variation of the Nyberg-Rueppel signature scheme.
• utils.py : Provides helper functions used throughout the project.
