Conscrypt - A Java Security Provider

Conscrypt is a Java Security Provider (JSP) that implements parts of the Java Cryptography Extension (JCE) and Java Secure Socket Extension (JSSE). It uses BoringSSL to provide cryptographic primitives and Transport Layer Security (TLS) for Java applications on Android and OpenJDK. See the capabilities documentation for detailed information on what is provided.

The core SSL engine has borrowed liberally from the Netty project and their work on netty-tcnative, giving Conscrypt similar performance.

Download

Conscrypt supports Java 8 or later on OpenJDK and KitKat (API Level 19) or later on Android. The build artifacts are available on Maven Central.

Download JARs

You can download the JARs directly from the Maven repositories.

OpenJDK (i.e. non-Android)

Native Classifiers

The OpenJDK artifacts are platform-dependent since each embeds a native library for a particular platform. We publish artifacts to Maven Central for the following platforms:

Classifier	OS	Architecture
linux-x86_64	Linux	x86_64 (64-bit)
osx-x86_64	Mac	x86_64 (64-bit)
windows-x86	Windows	x86 (32-bit)
windows-x86_64	Windows	x86_64 (64-bit)

Maven

Use the os-maven-plugin to add the dependency:

<build>
  <extensions>
    <extension>
      <groupId>kr.motd.maven</groupId>
      <artifactId>os-maven-plugin</artifactId>
      <version>1.4.1.Final</version>
    </extension>
  </extensions>
</build>

<dependency>
  <groupId>org.conscrypt</groupId>
  <artifactId>conscrypt-openjdk</artifactId>
  <version>2.5.2</version>
  <classifier>${os.detected.classifier}</classifier>
</dependency>

Gradle

Use the osdetector-gradle-plugin (which is a wrapper around the os-maven-plugin) to add the dependency:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'com.google.gradle:osdetector-gradle-plugin:1.4.0'
  }
}

// Use the osdetector-gradle-plugin
apply plugin: "com.google.osdetector"

dependencies {
  compile 'org.conscrypt:conscrypt-openjdk:2.5.2:' + osdetector.classifier
}

Uber JAR

For convenience, we also publish an Uber JAR to Maven Central that contains the shared libraries for all of the published platforms. While the overall size of the JAR is larger than depending on a platform-specific artifact, it greatly simplifies the task of dependency management for most platforms.

To depend on the uber jar, simply use the conscrypt-openjdk-uber artifacts.

Maven

<dependency>
  <groupId>org.conscrypt</groupId>
  <artifactId>conscrypt-openjdk-uber</artifactId>
  <version>2.5.2</version>
</dependency>

Gradle

dependencies {
  compile 'org.conscrypt:conscrypt-openjdk-uber:2.5.2'
}

Android

The Android AAR file contains native libraries for x86, x86_64, armeabi-v7a, and arm64-v8a.

Gradle

dependencies {
  implementation 'org.conscrypt:conscrypt-android:2.5.2'
}
