Generators
Deterministic and cryptographically secure generation utilities operating with local randomness.
Password Generator
Entropy (bits) = length × log₂(number of possible characters)
Create strong, random passwords in your browser. Choose the length and character types and see an estimate of how hard each password is to guess.
QR Code Generator
Bitstream packing + Reed-Solomon Galois Field GF(2^8) error correction polynomial division
Privacy-first vector QR code generator creating scannable codes for URLs, WiFi credentials, vCards, and plain text with SVG and PNG export.
UUID Generator
UUID layout: xxxxxxxx-xxxx-Vxxx-Nxxx-xxxxxxxxxxxx V = version (4 or 7), N = variant (8, 9, a or b) v7: first 48 bits = Unix time in milliseconds
Generate random UUID v4 or time-ordered UUID v7 identifiers, one at a time or up to 1,000 in bulk.
