Struct ToyDiffieHellman 

pub struct ToyDiffieHellman {
    pub p: u64,
    pub g: u64,
}

Toy Diffie-Hellman parameters (prime p, generator g).

WARNING

Educational only. Real DH requires carefully chosen safe primes and generators. This implementation is NOT secure.

Fields

p: u64

A prime modulus p

g: u64

A generator g of the multiplicative group mod p

Implementations

impl ToyDiffieHellman

pub fn public_key(&self, private: u64) -> u64

Compute the public key g^private mod p.

WARNING

Educational only.

pub fn shared_secret(&self, their_public: u64, my_private: u64) -> u64

Compute the shared secret their_public^my_private mod p.

Both parties derive the same value: (g^a)^b = (g^b)^a mod p.

Educational only. Does not defend against MITM attacks without authentication.
