What is Bit Entropy?

Bit Entropy is a mathematical measure of how much randomness or unpredictability is in a password. It is calculated by taking the pool of possible characters (Digits, Letters, Symbols) and the length of the string.

Benchmarks:
< 40 Bits: Very Weak. Can be cracked in seconds.
60-80 Bits: Strong. Secure against most standard brute-force attacks.
> 100 Bits: Unbreakable. Even supercomputers would take trillions of years to crack this.
