Hash Generator

Generate SHA-1, SHA-256, SHA-384, SHA-512, and MD5 hashes.

About this Hash Generator

Hash Generator computes SHA-1, SHA-256, SHA-384, SHA-512, and MD5 digests for checksums, cache keys, and integrity comparisons. Developers verify downloads; writers fingerprint document versions; students compare algorithmic outputs. Paste text or provide input, choose algorithms, and copy digests. Hashing runs in the browser so file contents and secret strings used for demos stay local. Hashes are one-way fingerprints, not encryption—do not hash passwords with MD5 or SHA-1 for storage; use proven password KDFs (bcrypt, scrypt, Argon2) in real auth systems. Publish SHA-256 checksums beside downloadable builds so users can verify mirrors. Hash canonicalized JSON (sorted keys) when fingerprints must stay stable. Never use a bare hash as an API authentication scheme without HMAC or signatures. Keep iterating with this hash generator workflow until the output matches your checklist.

How to use

  1. 1Enter the text (or content) to hash.
  2. 2Select algorithms such as SHA-256 or MD5.
  3. 3Generate the digest outputs.
  4. 4Copy the hash hex string you need.
  5. 5Compare against a known checksum when verifying files.

Frequently asked questions

Is MD5 safe for passwords?
No. MD5 and SHA-1 are unsuitable for password storage. Use a dedicated password hashing algorithm.
Why do tiny input changes change the hash totally?
Cryptographic hashes are designed for avalanche effects—useful for integrity checks.
Are hashes reversible?
Not practically for secure algorithms. Matching a hash means comparing, not decoding.
Which algorithm should I use for file integrity?
SHA-256 is a common modern choice when publishers provide that checksum.
Does whitespace affect the hash?
Yes. Exact bytes matter—including trailing newlines.
