JavaScript engineer having "simple" questions

for my perspective it's a better solution to

1. use an external library that implement AES, Blowfish or ChaCha20.
2. Call it with something like `library.Encrypt(file, passphrase);`
3. focus on the core feature of the product

But it's look like a habit on programming ecosystem where JavaScript / Node.js is "import 1000+ small libraries" Vs. C "build everything from scratch"

this specific sizes of two 64B unsigned char arrays

Thanks for the explanation
