Tink Java 1.13.0

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

This is Tink Java 1.13.0

To get started using Tink, see the setup guide.

What's new?

Bugs fixed:

• JwkSetConverter now encodes RSA public keys without leading zero, as required by RFC 7518.

Performance improvements:

• Encrypted keysets produced with BinaryKeysetWriter or TinkProtoKeysetFormat are now smaller, because the unused keyset info metadata is not written anymore. JsonKeysetWriter and TinkJsonProtoKeysetFormat still output this metadata.
• Tink now uses the JCE implementation of ChaCha20Poly1305 if available. This makes encryption with ChaCha20Poly1305 and XChaCha20Poly1305 about 2-3 times faster.
• AES-GCM is now about 20% faster.

API changes:

• For Android: Support for SDK 19 has been removed.
• Removed PrimitiveSet and Registry.registerPrimitiveWrapper from the public API. While these were in the public API, they have changed semantics in the past and will change more in the future. Code using either PrimitiveSet or Registry.registerPrimitiveWrapper will not work after upcoming changes. Instead of breaking users silently, we prefer to break during compilation. If affected, please file an issue on github.com/tink-crypto/tink-java/.
• For keyset that contain JWT keys, JwtSignatureConfig.register() or JwtMacConfig.register() now need to be called before the keyset is parsed. If not, calling keysetHandle.getPrimitive(...) will fail with an error message: "Unable to get primitive interface com.google.crypto.tink.jwt.JwtPublicKeySign for key of type ..." or "Unable to get primitive interface com.google.crypto.tink.jwt.JwtPublicKeyVerify for key of type ...".
• Removed the constructors of HmacKeyManager and HmacPrfKeyManager from the public API. These were never intended to be public, and we expect that nobody used either of them.
• Removed the constructors of com.google.crypto.tink.subtle.EciesAeadHkdfHybridDecrypt and com.google.crypto.tink.subtle.EciesAeadHkdfHybridEncrypt from the public API. These took as argument a EciesAeadHkdfDemHelper object whose only implementation was private to Tink. We are hence confident that this is unused.
• Removed test-only AndroidKeystoreKmsClient.setKeyStore. This function didn't work as expected, as in some places, still the real KeyStore was used. If you
