Tink setup

You can build Tink from source or use language-specific packages. The following instructions get you started.

After you've finished installing and setting up Tink, continue with the Next Steps at the end of this page.

C++

Tink provides the following C++ libraries:

Tink C++ (tink-cc)

Tink C++ depends on:

Tink C++ supports:

  • C++ >= 14

project(YourProject CXX)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_STANDARD 14)
include(FetchContent)

# Import Tink as an in-tree dependency.
FetchContent_Declare(
  tink
  URL       https://github.com/tink-crypto/tink-cc/archive/refs/tags/v2.3.0.zip
  URL_HASH  SHA256=363ce671ab5ce0b24f279d3647185597a25f407c3608db007315f79f151f436b
)
FetchContent_GetProperties(tink)
if(NOT googletest_POPULATED)
  FetchContent_Populate(tink)
    add_subdirectory(${tink_SOURCE_DIR} ${tink_BINARY_DIR} EXCLUDE_FROM_ALL)
endif()

add_executable(your_app your_app.cc)

Go

Tink provides the following Go libraries:

All the Tink Go libraries are published as Go modules that can be used with standard Go tooling or Bazel.

Tink Go (tink-go)

Go tooling

Running the following command from you project directory:

go get github.com/tink-crypto/tink-go/v2@v2.2.0

See the official Go documentation.

Tink Go AWS KMS extension (tink-go-awskms)

Go tooling

Run the following command from you project directory:

go get github.com/tink-crypto/tink-go-awskms/v2@2.1.0

See the official Go documentation.

Tink Go Google Cloud KMS extension (tink-go-gcpkms)

Go tooling

Run the following command from you project directory:

go get github.com/tink-crypto/tink-go-gcpkms/v2@v2.2.0

See the official Go documentation.

Tink Go HashiCorp Vault extension (tink-go-hcvault)

Go tooling

Run the following command from you project directory:

go get github.com/tink-crypto/tink-go-hcvault/v2@v2.2.0

See the official Go documentation.

Java

Tink provides the following Java libraries:

The Java version of Tink supports Java 8 or newer. You can either include the Tink Java Maven artifacts within your Maven or Gradle project, or use Bazel.

Tink Android is fully supported starting from API level 24. Most parts of Tink are expected to work starting from API level 21. The parts where Tink does not run out of the box with API level 21 are:

  • The JWT library requires API level 24 since it uses classes such as java.util.Optional. This limitation can be avoided with desugaring.
  • The classes in com.google.crypto.tink.integration.android are only fully tested starting from API level 23.
  • Some APIs in com.google.crypto.tink.streamingaead use SeekableByteBufferChannel which is only available from API level 24.

We note that due to technical reasons we only test Tink on Android on Google internal infrastructure. We don't expect any problems because of this, but if you encounter any problems please file an issue.

Tink Android requires no proguard configuration.

Tink Java (tink-java)

Maven

You can include Tink Java and the Tink Android library using Maven:

<dependency>
  <groupId>com.google.crypto.tink</groupId>
  <artifactId>tink</artifactId>
  <version>1.15.0</version>
</dependency>

If you are targeting Android, you can use tink-android from Gradle using:

dependencies {
  implementation 'com.google.crypto.tink:tink-android:1.15.0'
}

Bazel

The recommended way Bazel users can add Tink Java as a dependency is by installing the Maven release artifact using the rules_jvm_external tool in their WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

RULES_JVM_EXTERNAL_TAG = "6.1"
RULES_JVM_EXTERNAL_SHA ="d31e369b854322ca5098ea12c69d7175ded971435e55c18dd9dd5f29cc5249ac"

http_archive(
    name = "rules_jvm_external",
    strip_prefix = "rules_jvm_external-%s" % RULES_JVM_EXTERNAL_TAG,
    sha256 = RULES_JVM_EXTERNAL_SHA,
    url = "https://github.com/bazelbuild/rules_jvm_external/releases/download/%s/rules_jvm_external-%s.tar.gz" % (RULES_JVM_EXTERNAL_TAG, RULES_JVM_EXTERNAL_TAG)
)

load("@rules_jvm_external//:repositories.bzl", "rules_jvm_external_deps")

rules_jvm_external_deps()

load("@rules_jvm_external//:setup.bzl", "rules_jvm_external_setup")

rules_jvm_external_setup()

load("@rules_jvm_external//:defs.bzl", "maven_install")

maven_install(
    artifacts = [
        "com.google.crypto.tink:tink:1.15.0",
        # ... other dependencies ...
    ],
    repositories = [
        "https://maven.google.com",
        "https://repo1.maven.org/maven2",
    ],
)

If you want to build tink-java from source, for example to pin a specific commit, you can include it as an http_archive in your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

TINK_COMMIT="f4127f6b6ab9c367d41ade1f50db6f0ef9909044"
TINK_SHA256="e246f848f7749e37f558955ecb50345b04d79ddb9d8d1e8ae19f61e8de530582"

http_archive(
    name = "tink_java",
    urls = ["https://github.com/tink-crypto/tink-java/archive/%s.zip" % TINK_COMMIT],
    strip_prefix = "tink-%s" % TINK_COMMIT,
    sha256 = TINK_SHA256
)

load("@tink_java//:tink_java_deps.bzl", "TINK_MAVEN_ARTIFACTS", "tink_java_deps")

tink_java_deps()

load("@tink_java//:tink_java_deps_init.bzl", "tink_java_deps_init")

tink_java_deps_init()

# rules_jvm_external is imported and initialized by tink_java_deps and
# tink_java_deps_init.
load("@rules_jvm_external//:defs.bzl", "maven_install")

maven_install(
  artifacts = TINK_MAVEN_ARTIFACTS + # ... other dependencies ...
  repositories = [
      "https://maven.google.com",
      "https://repo1.maven.org/maven2",
  ],
)

ObjC

See the HOWTO on GitHub

Python

The Tink Python library, tink-py supports Python 3.8 or newer on macOS (x86-64 and ARM64), Linux (x86-64 and ARM64) and Windows (x86-64). The latest release is 1.10.0. It can be installed locally using Pip or used with Bazel.

Tink Python provides integrations with AWS KMS, Google Cloud KMS and HashiCorp Vault.

Pip

You can install the Tink Python binary release for your system from PyPI, by running the following command:

pip3 install tink==1.10.0
# Core Tink + Google Cloud KMS extension.
pip3 install tink[gcpkms]==1.10.0
# Core Tink + AWS KMS extension.
pip3 install tink[awskms]==1.10.0
# Core Tink + HashiCorp Vault KMS extension.
pip3 install tink[hcvault]==1.10.0
# Core Tink + all the KMS extensions.
pip3 install tink[all]==1.10.0

If a binary package is not published for your environment, pip automatically resorts to building the project using the source distribution published to PyPI. If this is the case, you need Bazel or Bazelisk and the protobuf compiler installed to successfully build the project.

Bazel

Bazel users can include Tink Python in their WORKSPACE file as follows:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "tink_py",
    urls = ["https://github.com/tink-crypto/tink-py/releases/download/v1.10.0/tink-py-1.10.0.zip"],
    strip_prefix = "tink-py-1.10.0",
    sha256 = "767453aae4aad6de4fbb4162992184aa427b7b27864fe9912c270b24c673e1cc",
)

load("@tink_py//:tink_py_deps.bzl", "tink_py_deps")
tink_py_deps()

load("@rules_python//python:repositories.bzl", "py_repositories")
py_repositories()

load("@tink_py//:tink_py_deps_init.bzl", "tink_py_deps_init")
tink_py_deps_init("tink_py")

Next steps

Once you've finished setting up Tink, continue with the standard Tink usage steps:

  • Choose a primitive – Decide which primitive to use based on your use case
  • Manage keys – Protect your keys with your external KMS, generate keysets, and rotate your keys
