🔐 Cryptography Examples

🔑 Basic Crypto Operations

Key generation, signing, and verification with multiple algorithms

-- Generate different types of keys
local rsa_key = crypto.generate_jwk("RS256")
local ecdsa_key = crypto.generate_jwk("ES256") 
local ed25519_key = crypto.generate_jwk("EdDSA")

-- Sign and verify messages
local message = "Hello, secure world!"
local signature = crypto.sign(rsa_key, message)
local public_key = crypto.jwk_to_public(rsa_key)
local is_valid = crypto.verify(public_key, message, signature)

🔏 HTTP Signatures

Secure API communication with request/response signing

-- Sign HTTP requests
local request = {
    type = "request",
    method = "POST",
    path = "/api/users",
    headers = { ["Host"] = "api.example.com" },
    body = '{"name": "Alice"}'
}

local signed = httpsig.sign(request, {
    jwk = client_key,
    key_id = "client-key-2024",
    headers = {"(request-target)", "host", "digest"}
})
