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

This is Tink 1.2.0 Release Candidate 2.

Note: Release Candidate 1 was private and used to test the Obj-C publishing process.

New languages: C++ and Obj-C

Tink 1.2.0 adds support for C++ and Obj-C. Both have been running in production at Google for a few months, and support the following algorithms:

  • Digital Signature: ECDSA over NIST curves
  • Hybrid Encryption: ECIES over NIST curves with AEAD (AES-GCM and AES-CTR-HMAC-AEAD) and HKDF

Support for AWS KMS will be added to the Tink C++ library in future release candidates. Support for Google Cloud KMS has to wait post 1.2.0 because of lack of Cloud KMS client library. The Tink Obj-C library supports reading/writing key material to/from iOS Keychain.

Please see the C++ HOWTO and the Obj-C HOWTO for usage.
