New APIs

This release does not add new functionality.

Bugfixes

Tink Java 1.17.0 fixes the following bugs:

• Memory leak in Prf. See https://github.com/tink-crypto/tink-java/issues/53. When computing Hkdf, Tink used allocateDirect to get a buffer which is only cleaned up asynchronously. This could lead to excessive memory consumption. Thanks to behrooz-stripe@ for reporting and fixing the issue!

Getting started

To get started using Tink, see the setup guide.

Maven:

<dependency>
    <groupId>com.google.crypto.tink</groupId>
    <artifactId>tink</artifactId>
    <version>1.17.0</version>
</dependency>

Gradle:

dependencies {
  implementation 'com.google.crypto.tink:tink-android:1.17.0'
}

Bazel:

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

RULES_JVM_EXTERNAL_TAG = "4.5"
RULES_JVM_EXTERNAL_SHA ="b17d7388feb9bfa7f2fa09031b32707df529f26c91ab9e5d909eb1676badd9a6"

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/archive/refs/tags/%s.zip" % 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:1.17.0",
        # ... other dependencies ...
    ],
    repositories = [
        "https://repo1.maven.org/maven2",
    ],
)

Alternatively, one can build Tink from source, and include it with http_archive:

http_archive(
    name = "com_github_tink_crypto_tink_java",
    urls = ["https://github.com/tink-crypto/tink-java/archive/refs/tags/v1.17.0.zip"],
    strip_prefix = "tink-java-1.17.0",
    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()

# ...

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