MD5, SHA-1, SHA-256, SHA-384, SHA-512 & SHA-3 — Instantly In Your Browser
Paste text or upload a file, choose an algorithm, and generate a cryptographic hash in one click. Supports MD5, SHA-1, the full SHA-2 family, and the full SHA-3 family. Compare your result against a known hash to verify file integrity. Everything runs in your browser — your data never leaves your device.
All hashing runs locally in your browser. No text or file you enter is ever transmitted to a server. These algorithms are not suitable for password storage.
A hash generator converts text or a file into a fixed-length string of characters called a hash or digest. The same input always produces the same hash, so hashes are used to verify that a downloaded file has not been corrupted or tampered with, to fingerprint data, and to detect duplicate files.
No. This tool runs entirely in your browser. Your text and files are never transmitted to any server or stored anywhere. Once you close the tab, the data is gone.
MD5 produces a 128-bit hash and is now considered cryptographically broken — it is fine for quick checksums but should never be used for security purposes. SHA-256 produces a 256-bit hash and is the current industry standard for file integrity, digital signatures, and other security-sensitive applications.
No. None of the algorithms on this page — MD5, SHA-1, SHA-256, SHA-384, SHA-512, or SHA-3 — are appropriate for storing passwords. These are general-purpose hash functions designed to be fast, which makes them easy for attackers to brute-force. Password storage requires a deliberately slow, salted algorithm such as bcrypt, scrypt, or Argon2.
SHA-3 is a newer hash family standardized by NIST in 2015, built on a different internal design (the Keccak sponge construction) than the SHA-2 family (which includes SHA-256 and SHA-512). SHA-3 is not a replacement for SHA-2 — both are currently considered secure — but it offers an alternative construction in case weaknesses are ever found in SHA-2.
Upload the downloaded file to this tool, select the same algorithm the publisher used (commonly SHA-256), generate the hash, and paste the publisher's posted hash into the comparison field. A match confirms the file is identical to the original; a mismatch means the file was corrupted, incomplete, or altered.

MD5, SHA-1, SHA-256, SHA-384, SHA-512, and SHA-3 are general-purpose hash functions and are not suitable for password storage. Always verify critical file integrity checks using multiple sources.
