SM9

Pure Rust implementation of the SM9 identity-based cryptographic algorithms as defined in the Chinese national standard GM/T 0044-2016 as well as ISO/IEC 11770.

Usage

Add the sm9 crate to your dependencies in Cargo.toml

[dependencies]
sm9 = "0.2.3"

Examples

(See encryption.rs for the full example.)

    use sm9::*;
    
    let usr_id = b"Bob";
    let txt = b"Chinese IBE standard";
    let m = Sm9::encrypt("master_public_key.pem", usr_id, txt);
    println!("{:02X?}", m);

    let msg = Sm9::decrypt("bob_private_key.pem", usr_id, m).expect("decrypt error");
    println!("{:02X?}", msg);
    assert_eq!(msg.len(), txt.len());
    assert_eq!(txt, msg.as_slice());

(See signature.rs for the full example.)

    use sm9::*;
    
    let m = b"Chinese IBS standard";
    let user_id = b"Alice";
    let sig = Sm9::sign(
        "master_signature_public_key.pem",
        "alice_signature_private_key.pem",
        m,
    );
    println!("{:02X?}", sig.h_as_ref());
    println!("{:02X?}", sig.s_as_ref());

    assert!(Sm9::verify(
        "master_signature_public_key.pem",
        user_id,
        m,
        &sig
    ));
