C++ 23, the planned next version of the C++ programming language due to be finalized in 2023, is set to move forward with support for a standard library module and faster compilation.

But criticisms have arisen in the past of how “dead batteries” in the standard library—outdated and hard-to-maintain modules—have outlasted their usefulness and ought to be removed.

The library is written in C, just like the PHP source code. Many companies like Keybase, Digital Ocean, Riseup, Yandex, Wire, and Zcash, already deploy Libsodium with their services.
