# Cryptopals
This repository has my [cryptopals](https://cryptopals.com/) solutions, which are a set of cryptography-related programming challenges. Each challenge is run as a test, stored under `sets/setN/chalM_test.go` for some set `N` and challenge `M`. The rest of the codes are stored under `pkg` and `internal`.
To run a specific set:
```sh
# N for set number
go test ./sets/setN
# e.g. running set 1 with verbose flag
go test ./sets/set1 -v
```
To run a specific challenge, similarly:
```sh
go test ./sets/setN/chalM_test.go -v
```
## TODO
- Add `internal/testing` utilities that prints expected / received kind of errors.
