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 already being used to secure data of many products such as AdMob, Google Pay, Google Assistant, Firebase, the Android Search App, etc.
Tink primarily uses Bazel to manage building and testing the project.
The recommended way to get started with Tink is to use Bazelisk. This tool is developed by the Bazel team and makes it easy to ensure usage of a version of Bazel that's compatible with the project.
As a starting point, the
performing simple tasks using Tink in a variety of languages.
Tink performs cryptographic tasks via so-called [primitives](docs/PRIMITIVES.md), each of which is defined via a corresponding interface that specifies the functionality of the primitive. For example, symmetric key encryption is offered via an [AEAD-primitive (Authenticated Encryption with Associated Data)](docs/PRIMITIVES.md#authenticated-encryption-with-associated-data), that supports two operations:
encrypt(plaintext, associated_data), which encrypts the given
associated_dataas additional AEAD-input) and returns the resulting ciphertext
decrypt(ciphertext, associated_data), which decrypts the given
associated_dataas additional AEAD-input) and returns the resulting plaintext
Before implementations of primitives can be used, they must be registered at runtime with Tink, so that Tink "knows" the desired implementations. Here's how you can register all implementations of all primitives in Tink:
import com.google.crypto.tink.config.TinkConfig; TinkConfig.register();
After implementations of primitives have been registered, the basic use of Tink proceeds in three steps:
- Load or generate the cryptographic key material (a
Keysetin Tink terms).
- Use the key material to get an instance of the chosen primitive.
- Use that primitive to accomplish the cryptographic task.
Here is how these steps would look like when encrypting or decrypting with an AEAD primitive in Java:
import com.google.crypto.tink.Aead; import com.google.crypto.tink.KeysetHandle; import com.google.crypto.tink.aead.AeadKeyTemplates; // 1. Generate the key material. KeysetHandle keysetHandle = KeysetHandle.generateNew( AeadKeyTemplates.AES128_GCM); // 2. Get the primitive. Aead aead = keysetHandle.getPrimitive(Aead.class); // 3. Use the primitive. byte ciphertext = aead.encrypt(plaintext, associatedData);

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.
