Password Analysis Details

The analyzer provides estimates for four different attack scenarios:

Attack Type	Rate	Description
Online (Unthrottled)	10/sec	Basic online attacks without rate limiting
Online (Throttled)	100/hour	Attacks against services with security measures
Offline (Slow Hash)	10K/sec	Attacks on properly hashed passwords (bcrypt, Argon2)
Offline (Fast Hash/GPU)	10B/sec	Attacks using GPUs or weak hashing algorithms (MD5, SHA-1)
