Installation

Tink C++

The core C++ library is tink-cc with 2.4.0 as the latest release.

Bazel

Bzlmod

Add this to your MODULE.bazel file:

bazel_dep(name = "tink_cc", version = "2.4.0")

WORKSPACE

Add this to your WORKSPACE file:

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

http_archive(
    name = "tink_cc",
    urls = ["https://github.com/tink-crypto/tink-cc/archive/refs/tags/v2.4.0.zip"],
    strip_prefix = "tink-2.4.0",
    sha256 = "06c4d49b0b1357f0b8c3abc77a7d920130dc868e4597d432a9ce1cda4f65e382",
)

load("@tink_cc//:tink_cc_deps.bzl", "tink_cc_deps")

tink_cc_deps()

load("@tink_cc//:tink_cc_deps_init.bzl", "tink_cc_deps_init")

tink_cc_deps_init()

CMake

Add tink-cc as an in-tree dependency.

cmake_minimum_required(VERSION 3.22)
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/v2.4.0.zip
  URL_HASH  SHA256=06c4d49b0b1357f0b8c3abc77a7d920130dc868e4597d432a9ce1cda4f65e382
)
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)
target_link_libraries(your_app tink::static)

Note: Tink defines the C++ standard using the TINK_CXX_STANDARD variable, which is 14 by default. If you want to propagate CMAKE_CXX_STANDARD to Tink, use set(CMAKE_CXX_STANDARD_REQUIRED ON).

AWS KMS Extension

The Tink C++ AWS KMS extension is tink-cc-awskms with 2.0.1 as the latest release.

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
