Cryptographically Secure Password Generator

Generate passwords with military-grade security using advanced cryptographic techniques. True randomness guaranteed with no predictable patterns.

Crypto.getRandomValues()
Uses the Web Crypto API for cryptographically secure random number generation
Rejection Sampling
Ensures uniform distribution by rejecting biased random values
Fisher-Yates Shuffling
Cryptographically secure shuffling prevents predictable character patterns

How Our Security Works

1

Random Selection

crypto.getRandomValues() generates true random numbers

2

Bias Elimination

Rejection sampling ensures uniform character distribution

3

Character Guarantee

At least one character from each selected type

4

Secure Shuffling

Fisher-Yates algorithm prevents pattern detection

Technical Implementation

Cryptographic Randomness

Web Crypto API

Uses browser's native cryptographic functions

Entropy Source

Hardware-based random number generation

Uniform Distribution

Rejection sampling eliminates modulo bias

Security Guarantees

Character Inclusion

Each selected type guaranteed in output

Pattern Prevention

Cryptographic shuffling prevents sequences

No Predictability

Each password is completely independent
