Tink is a multi-language, cross-platform library that provides simple and misuse-proof APIs for common cryptographic tasks.

This is Tink 1.4.0-rc2.

Changes

This release candidate adds things that we want to ship in 1.4.0, but didn't have a chance to add them to 1.4.0-rc1, such as:

• a proper fix for the infamous Protobuf issue in Tink for Android.
• a better go.mod config.
• many changes in Tink Python that didn't make the last release cut.

The complete list of changes since 1.4.0-rc1 can be found here.

We no longer offer prebuilt binaries for C++. Please check out this documentation for how to compile your application together with Tink using Bazel or CMake.

Known issues

• Tink Obj-C doesn't build. That is, you can't check out Tink Obj-C and build it yourself using Bazel. You can still use it in your apps by installing our prebuilt package, as noted above.

What's next

1.4.0 final should be out in 1-2 weeks, barring new issues.
