[+] Because we've removed common used libcrypto library (part of OpenSSL and its forks like LibreSSL) we should add some replacement of postquantum-proofed classic
    alghorythms. One of such algohrythms is Keccak hash functions, as fast as hell and OpenAES library  - AES because its symmetric alghorythm is good enought ever if N = NP
    ever in this variant you could let if to encrypt if you have exchanged with secret symmetric key for example in the real world.
    In anyway mostly and me expects that N != NP so postquantum math has a sence. If you think same - be aware or join to the process of development.
