Argon2 Binding for the JVM

This is a JVM binding for Argon2.

Maven

Add this repository:

<repositories>
  <repository>
    <snapshots>
      <enabled>false</enabled>
    </snapshots>
    <id>bintray-phxql-maven</id>
    <name>bintray</name>
    <url>https://dl.bintray.com/phxql/maven</url>
  </repository>
</repositories>

You can then use the following Maven coordinates:

<dependency>
    <groupId>de.mkammerer</groupId>
    <artifactId>argon2-jvm</artifactId>
    <version>2.0</version>
</dependency>

Gradle

repositories {
    maven {
        url  "https://dl.bintray.com/phxql/maven"
    }
}

dependencies {
    compile 'de.mkammerer:argon2-jvm:2.0'
}

Usage

This binding needs the Argon2 C library. Libraries for the following operation systems are included:

Linux x86
Linux x86-64
Windows x86
Windows x86-64
Darwin (OSX)

If your operating system isn't in the list, have a look at this documentation.

// Create instance
Argon2 argon2 = Argon2Factory.create();

// Read password from user
char[] password = readPasswordFromUser();

try {
    // Hash password
    String hash = argon2.hash(2, 65536, 1, password);

    // Verify password
    if (argon2.verify(hash, password)) {
        // Hash matches password
    } else {
        // Hash doesn't match password
    }
} finally {
    // Wipe confidential data
    argon2.wipeArray(password);
}

Technical details

This library uses JNA to communicate with the Argon2 C library.

Building it yourself
