Thank you for submitting an extension.

I'm a bit confused:

• Usually, base 64 conversion is used to embed binary data into a text document
• A hash is an irreversible process, base conversions are not hashing functions

Can you give a few use-cases that will help understand your extension purpose?

I used this encryption method, so base 64, to encrypt the saves and allow the user or developers to be able to decrypt the save directly in the game. This prevents us from having an external save, so in Jason format for example, which is accessible and visible to the player. This prevents, in quotes, your game from being hacked, but it can be used for many other things to recover sensitive data that can possibly be sent in databases, etcetera.

A base 64 conversion is not an encryption since anyone can access to the original text.
Also, if you convert a text from base 256 to base 64, it results in a bigger string, so It's not for compression either I guess.

For an exemple you get a big json If you convert it to base 64 you have a lower text. But it just for dissuade someone to check any text for modifie it. Obviously if you have an experience in dev it easy for uncrypt base64. WE have a real difference between hash and crypt. Crypt it just for hide something but it can be uncrypt. Hash it unhashable. Some friend want to "crypt" the save in base 64 just for save any data in json. 🙂 Le sam. 9 août 2025, 20:04, D8H ***@***.***> a écrit :
