You shouldnt be fetching a file url like that as:
- this forces people to need internet for this extension to work
- url could go down at any point
You should use a data.uri instead.
Also add /* global [library name here] */ to fix the lint errors

Ok being real here, jsdelivr isnt going down any time soon, and no they should find a way to import the library without using a script tag.

the desktop app still needs to work without internet (this is why the extension library there can only update when the app does, because it's stored offline).
for importing, i think using await import() and making the extension function async is a simple option (and probably also add /+esm to the jsdelivr url so that you can access the library from import()'s return value without adding stuff to the global scope), but you should still make the extension url a data url because of the offline part

maybe yeah but that does bring the question is it allowed because stuff like a script tag isnt allowed and they do similar things

this id should be the same as the extension ID

this name should be the same as the one listed on the gallery which you put as RSA

nitpick: please make the block titles lowercase so "generate RSA keys" as currently it does not follow scratch's conventions, also blocks are not sentence's so yeah

after doing what the other reviews suggests (removing the script tag) just remove this

nitpick: this could be customizable

instead of returning text which could be the same as the actual output value you should just return an empty string
| const crypt = new JSEncrypt(); | ||
| crypt.setPrivateKey(args.KEY); | ||
| const decrypted = crypt.decrypt(args.TEXT); | ||
| return decrypted ? decrypted : 'Decryption failed'; |

same goes here for the returning an empty string
