Generate PBKDF2 hashes with 10,000 iterations of SHA-256 for password storage simulation. Tune iterations to hardware — slower hashes resist brute force — free, local, no signup.
Compute SHA-1, SHA-256, SHA-384, or SHA-512 hashes of text content using the Web Crypto API. Code never leaves your device — formatting and validation run locally in your browser.
Generate HMAC signatures using a secret key and hash algorithm for API authentication. Code never leaves your device — formatting and validation run locally in your browser.
Generate invisible Unicode characters and blank text for bios, usernames, and formatting tricks. Post empty messages anywhere — free, local, copy-paste ready.
Extract text from a PDF and translate it between 20 languages. Output is plain text (PDF formatting is not preserved). Text limited to 5,000 characters.
Bcrypt/argon2 for passwords — fast hashes crack too easily to trust.
Unique salt per password, stored alongside the hash automatically.
Optional extra secret layered server-side over the salted hash.
No — hashing runs locally in your browser; unlimited saves on local tools.
