+# mac-kt
+
+`mac-kt` is a Kotlin Multiplatform library that provides common [Message Authentication Codes](https://en.wikipedia.org/wiki/Message_authentication_code).
+
+Supported algorithms:
+- HMAC
+
+## Installation
+
+Add the following to your `build.gradle.kts`.
+
+```kotlin
+repositories {
+    maven("https://git.infendro.com/api/packages/Infendro/maven")
+}
+
+dependencies {
+    implementation("com.infendro:mac:1.5.0")
+}
+```
+
+## Usage
+
+```kotlin
+fun main() {
+    // create an HMAC instance using SHA1
+    val hmac = HMAC(SHA1())
+
+    // generate MAC
+    val key = "secret".encodeToByteArray()
+    val value = "Hello World!".encodeToByteArray()
+    val mac = hmac.hash(key, value)
+}
+```
