Tink

A multi-language, cross-platform library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse. See also: https://developers.google.com/tink.

NOTE: Tink is moving!

As part of our roadmap we are splitting Tink into multiple GitHub repositories that will be hosted at github.com/tink-crypto and will be independently versioned.

Roughly, we are going to create one repository per language, library extension such as KMS (except Tink Python), and tools.

A few important highlights:

• The migration will be done gradually over the course of 2023 with a new release from each of the new repositories. Releases will be announced in our mailing list.
• We will keep updating each implementation/tool in github.com/google/tink for a specified amount of time; migrated implementations/tools will eventually stop being updated on github.com/google/tink. The support window depends on the specific implementation, as shown in the table below.
• New issues and pull requests should be created in the new repos.

Below is the list of resulting repositories, migration timeline and expected end of support.

NOTE: We are removing Tink for JavaScript/TypeScript

We are removing the Tink JavaScript/TypeScript library from our current Github repository (master branch). As part of our effort to migrate Tink to https://github.com/tink-crypto, we will not release an individual JavaScript/Typescript repository. Furthermore, the JavaScript/TypeScript directory in the current release branch (v1.7.0) will no longer be actively supported.

We aim to remove the JS/TS directory from the current Tink Github repository (master branch) on June 22, 2023. We will also deprecate the Tink npm package on this date.

See this tracking issue for more details.

Feel free to use our mailing list to raise any questions, issues or concerns.

Introduction

Using crypto in your application shouldn't have to feel like juggling chainsaws in the dark. Tink is a crypto library written by a group of cryptographers and security engineers at Google. It was born out of our extensive experience working with Google's product teams, fixing weaknesses in implementations, and providing simple APIs that can be used safely without needing a crypto background.

Tink provides secure APIs that are easy to use correctly and hard(er) to misuse. It reduces common crypto pitfalls with user-centered design, careful implementation and code reviews, and extensive testing. At Google, Tink is one of the standard crypto libraries, and has been deployed in hundreds of products and systems.

To get a quick overview of Tink design please take a look at slides from a talk about Tink presented at Real World Crypto 2019.

Current status

Java/Android, C++, Obj-C, Go, and Python are field tested and ready for production. The latest version is 1.7.0, released on 2022-08-09.

Javascript/Typescript is in an alpha state and should only be used for testing. Please see the intent to remove statement here.

Ubuntu | macOS ----------------------------------- | --------------------------------- |

Getting started

Documentation for the project is located at https://developers.google.com/tink. Currently, it details a variety of common usage scenarios and covers the Java and Python implementations. The site will be populated with more content over time.

Alternatively, you can look at all of the examples which demonstrate performing simple tasks using Tink in a variety of languages.

• Python

pip3 install tink

• Golang

go get github.com/google/tink/go/...

• Java

<dependency>
  <groupId>com.google.crypto.tink</groupId>
  <artifactId>tink</artifactId>
  <version>1.7.0</version>
</dependency>

• Android

dependencies {
  implementation 'com.google.crypto.tink:tink-android:1.7.0'
}

• Objective-C/iOS

cd /path/to/your/Xcode project/
pod init
pod 'Tink', '1.7.0'
pod install

Community-driven ports

Out of the box Tink supports a wide range of languages, but it still doesn't support every language. Fortunately, some users like Tink so much that they've ported it to their favorite languages! Below you can find notable ports.

WARNING While we usually review these ports, until further notice, we do not maintain them and have no plan to support them in the foreseeable future.

• Clojure
