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](CAPABILITIES.md) for detailed information on what is provided.

The core SSL engine has borrowed liberally from the [Netty](http://netty.io/) project and their
work on [netty-tcnative](http://netty.io/wiki/forked-tomcat-native.html), giving `Conscrypt`
similar performance.

Download
-------------
Conscrypt supports **Java 7** or later on OpenJDK and **Gingerbread (API Level
9)** or later on Android.  The build artifacts are available on Maven Central.

### Download JARs
You can download
[the JARs](http://search.maven.org/#search%7Cga%7C1%7Cg:%22org.conscrypt%22)
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](https://github.com/trustin/os-maven-plugin) to add the dependency:

```xml

  
    
      kr.motd.maven
      os-maven-plugin
      1.4.1.Final
    
  



  org.conscrypt
  conscrypt-openjdk
  2.5.2
  ${os.detected.classifier}

```

#### Gradle
Use the [osdetector-gradle-plugin](https://github.com/google/osdetector-gradle-plugin)
(which is a wrapper around the os-maven-plugin) to add the dependency:

```gradle
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
```xml

  org.conscrypt
  conscrypt-openjdk-uber
  2.5.2

```

##### Gradle
```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

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