Hash & Checksum

Generate hashes and checksums to verify files and protect text, with all the work done in your browser — so the original text or file never leaves your device. Text hashing covers MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160, CRC32, BLAKE2b, BLAKE3, xxHash64 and MurmurHash3, and HMAC generators add a secret key to SHA-1, SHA-256 and SHA-512 for authenticated hashes. Password hashing has its own tools — bcrypt, Argon2 and PBKDF2 — which are designed to be slow on purpose, so a stolen hash is hard to crack. File checksums let you drop in a downloaded file and get its MD5, SHA-1, SHA-256, SHA-512, CRC32 or BLAKE3 fingerprint, so you can compare it against the value the publisher lists and know the download arrived intact and unaltered. Developers use these tools to check API payloads and generate test hashes, and anyone verifying a download uses them to catch a corrupted or tampered file before running it. A hash is one-way, so the tools never store or transmit your input — and there is no account, no upload and no cost.
