Google Tink Cryptography Library

Tink is an open-source multi-language, cross-platform library that provides cryptographic APIs that are secure, easy to use correctly, and hard to misuse. It was originally developed by a group of cryptographers and security engineers at Google to provide a consistent and safe cryptographic interface for internal projects and the broader developer community. Tink serves as a foundational tool for secure data handling in modern applications, supporting fundamental primitives such as AEAD, MAC, digital signatures, and hybrid encryption.

As an open-source project hosted on GitHub, Tink is maintained primarily by Google engineers with contributions from the global developer community. It is designed to be wire-compatible across different programming languages including Java, C++, Go, Python, and JavaScript. The library's development focuses on preventing common security pitfalls through careful API design and the use of modern cryptographic standards like Protocol Buffers for keyset serialization.
