Bcrypt's 72-Byte Limit: Why Two Different Passwords Can Hash to the Same Value

Bcrypt silently truncates input at 72 bytes — meaning two passwords sharing the same first 72 bytes but differing afterward produce the identical hash. Here's why 72 specifically, how multi-byte Unicode characters (emoji especially) reach this limit far sooner than "72 characters" suggests, why pre-hashing with SHA-256 is a common mitigation, and why this isn't actually a meaningful security concern for typical passwords.

Credential Breaches and Stuffing Attacks: What Leaked Password Databases Reveal and How HIBP Works

Have I Been Pwned has indexed 12+ billion breached accounts. Here's what a leaked credential database actually looks like, how attackers use credential stuffing at scale, the k-anonymity trick that lets HIBP check passwords without seeing them, and why bcrypt salting defeats rainbow tables.

Why bcrypt: The History of Password Hashing, Cost Factors, and When Argon2 Is Better

SHA-1 and MD5 are fast by design — which is why GPUs crack them in hours after a breach. bcrypt's deliberate slowness and automatic salting are its defence. Here's how bcrypt works, the 72-byte limit, choosing a cost factor, and when Argon2 is the better choice.
