+# hash-kt
+
+`hash-kt` is a Kotlin Multiplatform library that provides common [Cryptographic Hash Functions](https://en.wikipedia.org/wiki/Cryptographic_hash_function).
+
+Supported algorithms:
+- MD5
+- SHA-1
+- SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512)
+- SHA-3 (SHA3-224, SHA3-256, SHA3-384, SHA3-512)
+- SHAKE (SHAKE128, SHAKE256)
+- Blake (Blake-224, Blake-256, Blake-384, Blake-512)
+- Blake2 (Blake2s, Blake2b)
+
+## Installation
+
+Add the following to your `build.gradle.kts`.
+
+```kotlin
+repositories {
+    maven("https://git.infendro.com/api/packages/Infendro/maven")
+}
+
+dependencies {
+    implementation("com.infendro:hash:1.7.0")
+}
+```
+
+## Usage
+
+```kotlin
+fun main() {
+    // hash some value using SHA-256
+    val value = "Hello World!".encodeToByteArray()
+    val hash = `SHA-256`().hash(value)
