VBA API call with nested JSON data
2 projects | reddit.com/r/vba | 10 Dec 2021
It basically uses the Dictionary object to create variables (e.g. with a dictionary in a dictionary) and after that using that library to transform it into a string. I'm using it in my project here: https://github.com/krijnsent/crypto_vba/blob/master/ModExchKucoin.bas
Where should I store API Keys?
1 project | reddit.com/r/vba | 9 Dec 2021
I agree with u/sslinky84 that there is no safe place in VBA. The main question is: what's the purpose of an API key in this case? From your description you are not linking an API-key to a single user, but have "one key to rule them all". So you probably want to prevent someone from grabbing your end-point and spamming it? In that case you're perfectly fine in creating one API-string in VBA and checking that on the server: it blocks the person who is opening a browser to fiddle with your end-point, but it does give you some security. The people who can get through are the ones that manage to crack open your VBA (assuming you have a password on the VBA). To make their life a bit harder you could instead of a "fixed string" as API key go for some kind of hash, as u/archn suggests. E.g.: take the rest of the post message that e.g. also includes a mandatory timestamp, make a simple hash of that (might even include a "fixed key", see e.g. https://github.com/krijnsent/crypto_vba/blob/master/ModHash.bas for some code).
Self made Excel/VBA triggers virus scan - what to do?
1 project | reddit.com/r/vba | 19 Mar 2021
I've built an open source VBA-Excel library to communicate with cryptocurrency exchanges ( https://github.com/krijnsent/crypto_vba ) and have my code available as .bas and in an .xlsm file. A couple of days ago someone posted an issue that my xlsm file triggered a Windows defender alert. At my pc this doesn't happen, the AVG virus scanner also won't show anything.
