Hash API keys using SHA-256 for secure storage. Never store raw API keys — hash them before persisting to your database. Code never leaves your device — formatting and validation run locally in your browser.

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.
Generate secure API keys with configurable length, character set, and optional prefix. Use with any authentication scheme.
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.
Share secrets securely via self-decrypting note links — AES ciphertext in the URL fragment, key in the link query. Send passwords without trusting inboxes — local crypto-js AES, free, no signup.
Translate pasted SRT or VTT subtitle text into 9 languages (Spanish, French, German, Japanese, Chinese, Hindi, Portuguese, Russian, Arabic) while preserving every timestamp — AI-powered with your own API key, text never stored.
Store hashes, compare on arrival — leaked databases reveal nothing usable.
For key storage yes; password storage needs bcrypt/argon2 instead.
Add a per-key salt before hashing to defeat rainbow tables outright.
No — hashing runs locally in your browser, free with no signup.
