Ordinal Crypto 🔐

The cryptography library for the Ordinal Platform

Usage

let (priv_key, pub_key) = ordinal_crypto::generate_exchange_keys();
let (fingerprint, verifying_key) = ordinal_crypto::signature::generate_fingerprint();

let content = vec![0u8; 1215];

// MAX pub keys: 65,535
let pub_keys = vec![pub_key];

let encrypted_content =
    ordinal_crypto::content::encrypt(&fingerprint, &content, pub_keys).unwrap();

let (encrypted_content, encrypted_key) =
    ordinal_crypto::content::extract_components_for_key_position(&encrypted_content, 0)
        .unwrap();

let decrypted_content = ordinal_crypto::content::decrypt(
    Some(&verifying_key),
    priv_key,
    &encrypted_key,
    &encrypted_content,
)
.unwrap();

assert_eq!(decrypted_content, content);

Format

• keys count header = 2 bytes
• encrypted keys = 72 bytes (max is 65,535 or 4.71852 mb)
• one-time public key = 32 bytes
• nonce = 24 bytes
• inner signature = 64 bytes (encrypted along with the content to preserve deniability)
• Poly1305 MAC = 16 bytes
