How is this calculated?

Password entropy is a measure of the unpredictability of a password. It is calculated based on the size of the pool of characters used (R) and the length of the password (L).

Formula:
Entropy = log₂(R^L) = L × log₂(R)

Pool Sizes (R):
Numbers: 10 | Lowercase: 26 | Uppercase: 26 | Symbols: 32

Security Benchmarks:
< 40 bits: Very Weak
40-60 bits: Weak
60-80 bits: Moderate
80-128 bits: Strong
128+ bits: Very Strong
