## What it is
Tink is a multi-language, cross-platform open source cryptographic library from Google that provides secure, easy-to-use APIs for encryption, signing, and key management, designed to be hard to misuse. This original repository has been made read-only after the project split into separate language-specific repositories under the tink-crypto GitHub organization.

## Use cases
- encrypt and decrypt data with safe defaults
- sign and verify messages without crypto expertise
- manage cryptographic keys safely
- add AEAD encryption to a Java or Go application
- avoid common cryptographic implementation pitfalls
- implement hybrid encryption or MACs in production systems

## When to choose
- you need battle-tested, misuse-resistant cryptographic APIs in Java, C++, Go, Python, or Obj-C
- your team lacks deep cryptography expertise but needs secure primitives
- you want consistent crypto APIs across multiple languages and platforms

## When to avoid
- you need the actively maintained versions - use the split repositories at github.com/tink-crypto instead
- you need the JavaScript/TypeScript implementation, which was only alpha and slated for removal
- you need low-level control over cryptographic primitives or custom algorithms
- you require a library still developed in this monolithic repository

## Facets
- artifact type: library
- maturity: maintenance
- function: cryptography, security, auth
- domain: security, developer-tools, privacy
- platform: jvm, cpp, go, python, cross-platform, windows
- tags: crypto-api, key-management, encryption, digital-signatures, google, misuse-resistant, multi-language, archived-repo, android, macos, linux
