# cryptopals
Challenges from https://cryptopals.com/.
WARNING: This is an academic proof-of-concept prototype, and in particular has not received careful code review. This implementation is NOT ready for production use.
## Methodoly
_DIY, build everything from scratch_
- minimum dependencies (crates).
- implement each and every thing.
- should be modular and can be used outside this project.
## Project Structure
This project is organised as a Cargo Workspace with two types of crates, challenges and utiltiy crates.
- [`challenges`](./challenges) - Crates for individual Problem Set and each crate contain only tests which represent the challanges and no other logic.
- [`packages`](./packages) - Utility crates like, aes, hex, base64, etc.
## `packages`
Utiltiy crates which are complelety functional on thier own to be used outside the scope of this project.
- ### [`aes`](./packages/aes)
Implementations for AES128, AES192, AES256.
- Complete AES Cipher & Inver Cipher implementation. (https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.197.pdf)
- Supports multiple padding schemes and block modes.
- Supports PKCS7 Padding Scheme.
- Supports CBC & ECB Block modes.
- ### [`enscoring`](./packages/enscoring)
English text scoring & metric utilites.
- Based on English character frequency table. (https://en.wikipedia.org/wiki/Letter_frequency)
- Use _Bhattacharyya coefficient_ for calculating score for given english text. (https://en.wikipedia.org/wiki/Bhattacharyya_distance)
- ### [`naivebase64`](./packages/naivebase64)
Naive Base64 encoding & decoding implementation.
- ### [`hex`](./packages/hex)
Hex encoding and decoding from hex string implementation.
- ### [`xor`](./packages/xor)
Utiltiy methods for XOR based key encryptions.
- Break Single XOR Key
- Break Repeating XOR Key
## Progress
- [x] Set 1 (Completed)
- [ ] Set 2 (In progress)
- [ ] Set 3
- [ ] Set 4
- [ ] Set 5
