// At the same time it'd be the best if we avoided all special characters, such as '/' found e.g. in base64, as we can't be sure that it's not a prohibited character in regards to native OS implementation
// Because of that, SHA256 is sufficient for our case, as it generates alphanumeric characters only, and is barely 256-bit long. We don't need any kind of complex cryptography or collision detection here, any hashing will do, and the shorter the better
