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

This is Tink 1.3.0 Release Candidate 1

Changes

The complete list of changes since 1.2.2 can be found here.

The main changes include:

new language: Tink in Go, with primitives MAC, AEAD (incl. KMS envelope), deterministic AEAD, hybrid encryption and digital signatures (see supported primitives and GOLANG HOWTO for details)
C++ deterministic AEAD (AES-SIV) and streaming AEAD (AES-GCM-HKDF-STREAMING)
C++ KMS-AEAD and KMS-envelope-AEAD, incl. integration with AWS KMS and GCP KMS.
RSA-signatures for Java and C++ (RSA-SSA-PKCS1, RSA-SSA-PSS)
ED25519 signatures for C++, Obj-C, and Go

Please note that Tink JavaScript and Tink Python are not a part of this release. Moreover, streaming envelope encryption (for Java and C++) has been de-prioritized and also is not a part of this release.
