 ### randRange()
 Usages:  
 ```ts
-randRange(min: number, max: number): number
-randRange(max: number): number
+randRange(min: number, max: number, enhancedEntropy?: boolean): number
+randRange(max: number, enhancedEntropy?: boolean): number
 ```
   
 Returns a random number between `min` and `max` (inclusive).  
 If only one argument is passed, it will be used as the `max` value and `min` will be set to 0.  
   
+If `enhancedEntropy` is set to true (false by default), the [Web Crypto API](https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues) is used for generating the random numbers.  
+Note that this takes MUCH longer, but the generated IDs will have a higher entropy.

-⚠️ Not suitable for generating anything related to cryptography! Use [SubtleCrypto's `generateKey()`](https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/generateKey) for that instead.  
+If `randomCase` is set to true (which it is by default), the generated ID will contain both upper and lower case letters.  
+This randomization is also affected by the `enhancedEntropy` setting, unless there are no alphabetic characters in the output in which case it will be skipped.
