This is Guardian Project's development fork of the Conscrypt TLS Provider developed as part of the DEfO Project with Tolerant Networks. We are implementing Encrypted Client Hello (ECH) and MASQUE here, as well as any bits of SVCB that helps with ECH and/or MASQUE. We are also making it available for anyone to try. There are alpha releases available on Maven Central:
implementation 'info.guardianproject.conscrypt:conscrypt-android:2.6.alpha1647601986.job2220801545'
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.

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.
You can download the JARs directly from the Maven repositories.
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) |
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>
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
}
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.
<dependency>
<groupId>org.conscrypt</groupId>
<artifactId>conscrypt-openjdk-uber</artifactId>
<version>2.5.2</version>
</dependency>
dependencies {
compile 'org.conscrypt:conscrypt-openjdk-uber:2.5.2'
}
The Android AAR file contains native libraries for x86, x86_64, armeabi-v7a, and arm64-v8a.
dependencies {
implementation 'org.conscrypt:conscrypt-android:2.5.2'
}
