Tink v1.2.0-rc4 Release Notes

Release Date: 2018-08-01 // almost 6 years ago

  • 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 4.

    🔄 Changes

    🚀 The complete list of changes since Release Candidate 3 can be found here.

    🚀 Please ignore RSA-related changes; RSA is not part of 1.2.0 release.

    🆕 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:

    • AEAD: AES-EAX, AES-GCM, AES-CTR-HMAC-AEAD
    • MAC: HMAC-SHA2
    • 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.
