This fixes a few issues. First, the comment is a little confusing. The
value is an IA5String. The issue isn't whether it might accidentally be
a T61String, but that its contents may be invalid for an IA5String.

Next, I've replaced ASN1_PRINTABLE_type with a loop. ASN1_PRINTABLE_type
does actually work, but it's normally used in OpenSSL to auto-detect a
string type for a Latin-1 string, which is a little confusing.

Finally, I've tweaked this so it does not rely on the ASN1_STRING being
NUL-terminated. The ASN1_STRING is almost always NUL-terminated, but
best not to rely on this. (See CVE-2021-3712.)

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.

Mailing List:


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 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)


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




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

buildscript {
  repositories {
  dependencies {
    classpath ''

// Use the osdetector-gradle-plugin
apply plugin: ""

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.

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'
