Configurable size for file uploading

[okolya]

yopass/website/src/createSecret/Upload.tsx

Line 20 in 7fd2b38

const maxSize = 1024 * 500;

It would be nice to use env variable such as MAX_FILE_UPLOAD to configure maximum file size.

Additional information :
File limit is hard-coded in frontend and backend

yopass/cmd/yopass-server/main.go

Line 26 in b439055

pflag.Int("max-length", 10000, "max length of encrypted secret")

Memcached max limit is 1 Mo, Redis has a 512 Mo limit.

The limit is also in the crypto, async crypto simply cannot encrypt big messages/files. For that you need a hybrid approach.

Actually you can adjust the memcached limit like this:

memcached -I 10m  # Allow objects up to 10MB

If you change the maxSize constant and run the yopass server with a bigger max-length then uploading bigger files is possible.

I don't know the exact limit for the crypto stuff though.

But having a configurable maxSize for file sizes would be absolutely possible, because I tried it in this PR: #1154

That needs a rework though with validating the size on the server and returning an error to the client.
If you feel like doing that @okolya then please go ahead! :)

@okolya If you want something that works rn you can check out a similar project I made, can configure the size there.

@jhaals are there any plans to support larger file uploads in the near future?
