ipcrypt was designed by Jean-Philippe Aumasson to encrypt IPv4 addresses with 16-byte keys, where the result is still an IPv4 address.

Derived from the implementation at: https://github.com/veorq/ipcrypt

lib.rs:

ipcrypt was designed by Jean-Philippe Aumasson to encrypt IPv4 addresses with 16-byte keys, where the result is still an IPv4 address.

Derived from the implementation at: https://github.com/veorq/ipcrypt

As input and output this implementation takes various types representing a sequence of 4 bytes. u32 is interpreted as big endian (network order; for consistency with how IPv4 adresses are represented as u32).

This crate supports a no-std feature which removes support for Ipv4Addr (because it's not available in core).

Example

use std::net::Ipv4Addr;
let addr = "127.0.0.1".parse::<Ipv4Addr>().unwrap();
println!("{}", ipcrypt::encrypt(addr, b"some 16-byte key"));
