Tink

NOTE: Tink moved to github.com/tink-crypto and this repo is no longer active!

As planned, we have split Tink into multiple GitHub repositories that are hosted at github.com/tink-crypto. As a consequence, we made this repository read-only and it is not going to be maintained moving forward.

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.

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.

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

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.
