Security
File and text encryption (AES-GCM with PBKDF2), TOTP codes, file hashing and passphrase generation. All Web Crypto in the page — the whole point is that the plaintext and the key never reach a server.
File EncryptorEncrypt any file with a password entirely in your browser — the file never leaves your device. AES-GCM-256 with PBKDF2 (310,000 iterations); decrypt the .enc file the same way, offline.Text EncryptorEncrypt a message with a password right in your browser — the text and password are never uploaded or stored. AES-GCM-256 + PBKDF2 packed as portable Base64 you can paste anywhere and decrypt later.TOTP Code GeneratorGenerate RFC 6238 authenticator (2FA) codes from a Base32 secret entirely in your browser — the secret is never sent, stored, or logged. Supports 6/8 digits, 30/60 s periods, SHA-1/256/512, with a live countdown.File Hash / ChecksumCompute SHA-256, SHA-1, SHA-384 and SHA-512 checksums of any file locally — the file is hashed in your browser and never uploaded. Paste an expected checksum to verify a download instantly.Passphrase GeneratorGenerate memorable Diceware passphrases from the EFF wordlist with cryptographically secure randomness — created in your browser, never sent or stored. Word count, separators, capitalization, numbers and a live entropy estimate.
