Cryptopals

crypto challenges made fun

Chipping away at em', work in progress...

Indeed there is overlap between the challenges and one could build a standard lib. But, instead, I wanted each challenge to be its own contained unit.

Usage

go get -u github.com/mfridman/cryptopals/...

# assuming you are in your GOPATH
cd src/github.com/mfridman/cryptopals/set-1/chal-6
go run main.go

Set 1: Basics

• solution ........ Convert hex to base64
• solution ........ Fixed XOR
• solution ........ Single-byte XOR cipher
• solution ........ Detect single-character XOR
• solution ........ Implement repeating-key XOR
• solution ........ Break repeating-key XOR
• AES in ECB mode
• Detect AES in ECB mode

Misc

func factorial(n uint64) uint64 {
    if n > 0 {
        result := n * factorial(n-1)
        return result
    }
    return 1
}
