react-native-quick-base64 VS js-spark-md5

I haven't used it myself but it can be worth to try https://github.com/craftzdog/react-native-quick-base64

I have a React Native project with some JSI native modules implemented in C++ like react-native-quick-base64. Today I upgraded Android Studio to 4.2.1, and it failed to build my project with the following CMake error:

react-native-quick-base64 4x faster on iOS

ActiveStorage uses the SparkMD5 library for MD5 hashing. I don't know enough about the library to know if MD5 is necessary or if we could use SHA-x hashing or similar. SparkMD5 is roughly 2.5kb and ActiveStorage is ~5kb overall, which means MD5 hashing accounts for roughly half the library.

However, RN has still a lack of binary support. Unlike NodeJS, RN doesn't come with native modules for dealing with binary data out of the box, like crypto and Buffer. When it comes to processing binary data, calculating a digest hash like SHA-1 and MD5 and converting from/to hex and base64 are popular tasks. To accomplish those tasks, you have to use JavaScript libraries like spark-md5 and buffer. If you need crypto module, you have to install rn-nodeify and a bunch of polyfill libraries, which eventually messes up your project and makes it hard to maintain. So, implementing the end-to-end encryption in React Native has been a big challenge for me.
