Security & Encoding Tools
Hash generators and secure password tools, computed locally with the Web Crypto API.
Hash Generator
Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text instantly via the Web Crypto API.
Password Generator
Generate cryptographically random strong passwords. Choose length, character sets and exclude look-alike characters.
Hash Collision & Cracking Simulator
Interactive demos of the birthday attack and brute-force preimage search on truncated hashes. Educational and hands-on.
TOTP Code Generator
Generate time-based one-time passwords (TOTP) from a Base32 secret or an otpauth:// URI: 6/8 digits, 30/60s periods, SHA-1/256/512, with the current code, its remaining seconds and the next code.
File Checksum (MD5 / SHA-256)
Drop files to compute MD5, SHA-1 and SHA-256 in one pass, then paste the published checksum to confirm a download is intact and untampered.
