crypto_vba VS VBA-Expressions

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

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).

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.

I am mainly using Cryptocompare, but if you want to use CoinGecko, check out my code, it has the basics: https://github.com/krijnsent/crypto_vba/ It has most of the essentials: connecting Excel to web, handling Json and some API examples.

So, if a Dominican needs to calculate the taxes that will be charged to them monthly, they should take pencil and paper, compute the annual amount of income and apply the corresponding formula, or they can use the following code in conjunction with VBA Expressions and get their result in a simple way.

Systems of linear equations have been taught since high school, they are of utmost importance in mathematics. Although Excel is possible to solve, manually, equations using matrix inverse and matrix multiplication. Today we will show you a practical way to solve such problems using VBA Expressions.

Here is a direct GitHub link to VBA Expressions Best regards!

After this publication, which details the reason why VBA Expressions turned out to be the most feasible option to solve the problem of integrating an expression evaluator with CSV Interface, it is time to address the process of integrating the evaluation capabilities and the ease with which this goal was achieved.

After a long search for something similar to the above, I decided to experiment and test the veracity of a warning that read: "... rather, it evaluates the infix expression directly. This approach is slightly more complicated than the traditional one". Then, I chose to develop an evaluator with its own grammar and a different approach to handle mathematical expressions. The solution I came up with is so called VBA Expressions. With VBA Expressions we can evaluate a variety of mathematical expressions, being able to work with arrays defined by text strings as in Java. A notorious feature is the ability to work with variables (Pi.e * 5.2Pie.1 + 3.1Pie), constants (3pi+ln(2e)), floating point numbers ((1.434E3+1000)*2/3.235E-5) and Boolean values (x>0 & Sqr(x-Ln(2))>=3 | tan(x)<0).
