Entropy for Random Password Generation
Count uncertainty when every character choice independent and equally likely.
Your numbers
Entropy wey random generation give
Na only independent uniform random generation this cover, no be password wey person choose. No enter real password; password field no dey.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use H = L×log₂(A). L na password length wey dem sample independently, A na alphabet size, and H na entropy for bits.
Count uncertainty when every character choice independent and equally likely.
Example wey show the calculation
- Number of random characters
- 12
- Number of characters for the alphabet
- 64
- Entropy wey random generation give
- 72 bits
Where e fit work and limits
Na only independent uniform random generation this cover, no be password wey person choose. No enter real password; password field no dey.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
