  • GitHub repo Tink

    Tink is a multi-language, cross-platform, open source library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse.

    Project mention: Harmony Crypto: Multi-process Encrypted SharedPreferences | reddit.com/r/androiddev | 2021-06-01

    Also, given that Google used Tink for Encrypted SharedPreferences, I had to make some modifications there to allow proper usage of Harmony Crypto. The problem I ran into was that Tink used Android SharedPreference to store keys, but didn't allow for any SharedPreference object to be passed in, which meant that Tink was not process safe. That led to making this PR (https://github.com/google/tink/pull/493), but working around the problem for the meantime by creating custom classes within the Tink package space to be used in the Harmony Crypto project.

    Project mention: New to graphics development, where should I start? | reddit.com/r/cpp | 2021-06-14

    Last point I'd mention is, if this seems overwhelming and there's too much to learn here you could start with either a smaller project like this one https://github.com/ssloy/tinyrenderer or go the engine route and let an engine take care of all the platform and API details and you can focus exclusively in the gfx like here: https://catlikecoding.com/unity/tutorials/ .

    I was starting a project that needs to read data with rest API and I'd like to use cpprestsdk from Microsoft. But it's readme says that's in maintenance mode and it's not recommended for new projects... I'd like to know why it's in maintenance mode, and if it will be abandoned. Also, if there's some equivalent library for cpp, instead of creating the business logic from scratch, i.e. with boost::beast.
