Free, fast and private security utilities, generate passwords, hashes and more right in your browser. No sign-up.
ToolBrainy's security tools help you protect accounts and verify data without installing software or trusting a remote server. Generate strong random passwords, measure how resistant an existing password is to guessing and brute-force attacks, create MD5, SHA-1 and SHA-256 hashes for checksums, and produce cryptographically secure random numbers — all processed entirely inside your browser. Nothing you type is transmitted, logged, or stored, which makes these tools safe to use even with sensitive values. Secure Print Share is the one exception. The file you send is encrypted before it is stored, unlocked only by a 6-digit PIN, and deleted once it has been printed.
Whether you are hardening a login, generating a unique key, or verifying the integrity of a downloaded file, every tool here is completely free, works on any device, and needs no sign-up. Pick a tool above to get started in seconds.
