Passwords, 2FA codes, hashes, and encryption.
Passwords
Generate strong random passwords in your browser: choose length and character types, skip look-alike characters, and make up to 500 at once.
Open tool →Passwords
Generate strong, memorable passphrases from the EFF's 7,776-word list, picked with secure randomness. Choose word count, separators, and capitals.
Open tool →Passwords
Generate random 4, 6, or 8-digit PINs that skip easy guesses like 1234, 1111, years, and dates. Secure randomness, generated in your browser.
Open tool →Passwords
Check how strong a password really is: estimated crack times, the words and patterns that make it guessable, and tips to improve it. Never leaves your browser.
Open tool →Keys
Generate random strings, API keys, and secret keys: pick the length and characters (hex, Base64url, alphanumeric, custom) or a key size in bytes. Cryptographically secure.
Open tool →2FA
Get live 2FA codes from a TOTP secret or otpauth:// link, check a code, or create a new secret with a QR code for authenticator apps. RFC 6238.
Open tool →Hash
Generate MD5, SHA-1, SHA-256, SHA-512, SHA-3, BLAKE, and CRC32 hashes of text as you type, create HMAC signatures, and check a hash for a match.
Open tool →Checksum
Calculate SHA-256, MD5, SHA-1, SHA-512, and other checksums for files of any size, and verify downloads against a published hash or SHA256SUMS file.
Open tool →Encrypt
Encrypt a message or note with a password using AES-256-GCM, and decrypt it later. Runs in your browser — the text and password never leave the page.
Open tool →Encrypt
Encrypt any file with a password (AES-256-GCM) before storing or sharing it, and decrypt it later — up to 1 GB, entirely in your browser.
