Apple to Develop CryptoKit Framework

Using CryptoKit, developers will be able to perform cryptographic operations, including hashing and key generation

Apple is going to present a set of tools for developers CryptoKit, integrated into the new iOS 13. It is reported by The Block.

It is reported that with the help of CryptoKit, developers will be able to perform cryptographic operations, including hashing and key generation. This will increase the security of applications and automate the execution of tasks.

It is also known that the toolkit will allow you to interact with both private keys managed by the Secure Enclave system and public ones, as well as generate encryption / decryption keys for message authentication.

For the first time, developers can leverage the secure enclave to manage a user’s keys in an iPhone, achieving a similar level of security to hardware wallets.

Apple is interested in blockchain technology. So, in February, the company reported to the US Securities and Exchange Commission (SEC) on the observance of human rights in a global network of suppliers of raw materials for production. Notably, the document said that Apple was involved in the development of the Blockchain Handbook for the Responsible Business Alliance (RBA) Initiative for Mineral Supply Chains.

Google to Introduce Tink Cryptographic Library

Google already uses Tink in projects like AdMob, Google Pay, Google Assistant, Firebase and the Android Search App

Google introduced the open cryptographic library called Tink with support for Java, C ++ and Objective-C, as well as experimental support for Go and JavaScript. Product primitives use the BoringSSL and the Java Cryptography Architecture framework.

Even small errors in the use of cryptographic methods can have serious consequences, and they are carefully study for decades. Many developers do not have so much time, so when creating a new tool, the company tried to reduce the number of potential errors with cryptographic APIs. Google already uses Tink in projects like AdMob, Google Pay, Google Assistant, Firebase and the Android Search App.

These primitives are used in the core of the library:

  • AEAD (Authenticated Encryption with Associated Data) for symmetric encryption of blocks and data streams over a fixed key. The tool does not require the definition of specific algorithms and their parameters. With it, you can quickly perform encryption and decryption operations:
    import com.google.crypto.tink.Aead;
     import com.google.crypto.tink.KeysetHandle;
     import com.google.crypto.tink.aead.AeadFactory;
     import com.google.crypto.tink.aead.AeadKeyTemplates;
     // 1. Generate the key material.
     KeysetHandle keysetHandle = KeysetHandle.generateNew(
     AeadKeyTemplates.AES256_EAX);
     // 2. Get the primitive.
     Aead aead = AeadFactory.getPrimitive(keysetHandle);
     // 3. Use the primitive.
     byte[] plaintext = ...;
     byte[] additionalData = ...;
     byte[] ciphertext = aead.(plaintext, additionalData);
  • The MAC (Message Authentication Codes) provides message authentication codes.

In Tink, there are functions for creating a digital signature and its verification, as well as the functions of fast hybrid encryption.

Features of work
Each primitive supports stateless mode operation, secure copy operations and the use of keys with a length of 128 bits. The library automatically blocks potentially unsafe operations, for example, downloading keys from unencrypted files on the disk. Tink provides an API for rotating keys and interacting with external key management systems: Google Cloud KMS, Amazon KMS, Android Keystore and Apple iOS KeyChain.

The library has a modular architecture, allows you to connect custom primitives and replace them with existing code files without changing the final applications. From Tink, you can exclude part of the tools. For example, if the program only uses digital signature verification, you can remove symmetric encryption components to reduce the application code size.

In August 2018, the creators of the VPN protocol, WireGuard, announced the creation of the Zinc cryptographic library, which, upon introduction into the core Linux kernel, will accelerate the process of data encryption through a simplified set of crypto algorithms.
