How to use in browser

<script src=crypto-lite.js></script>

<script>
crypto.sha1("secret")
// e5e9fa1ba31ecd1ae84f75caaa474f3a663f05f4
crypto.sha256("secret")
// 2bb80d537b1da3e38bd30361aa855686bde0eacd7162fef6a25fe97bf527a25b
crypto.hmac("sha1", "key", "message")
// 2088df74d5f2146b48146caf4965377e9d0be3a4
crypto.hmac("sha256", "key", "message")
// 6e9ef29b75fffc5b7abae527d58fdadb2fe42e7219011976917343065f58ed4a
crypto.pbkdf2("password", "salt", 1, 20, "sha1")
// 0c60c80f961f0e71f3a9b524af6012062fe037a6
crypto.hotp("secret", { counter: 1, digits 6, algo: "sha1" })
crypto.totp("secret", { time: Date.now(), t0: 0, step: 30, digits 6, algo: "sha1" }) // Defaults
</script>

How to use in node.js

Although it should work in node.js, you should use native api there.

npm install crypto-lite

var crypto = require("crypto-lite").crypto
