Hash Generator

Generate MD5, SHA-1, SHA-256 or SHA-512 hashes from one input.

The Hash Generator computes four of the most common digests from a single input: MD5, SHA-1, SHA-256 and SHA-512. Choose the algorithm and read the hexadecimal hash instantly — useful when a vendor, framework or legacy system asks for one specific digest type.

Each algorithm serves a different era and purpose: MD5 and SHA-1 are legacy (fast, but cryptographically broken — fine for simple integrity checks, not security), SHA-256 is today's default standard, and SHA-512 offers a larger 512-bit digest often seen in high-integrity and certification contexts. The tool notes each algorithm's status so you can pick appropriately.

All computation is local — MD5 runs in-page and the SHA family through your browser's Web Crypto — so nothing you hash leaves your device. A one-line explanation reminds you why plain hashes are not suitable for password storage.

Current standard — Git commits, TLS, most verification tools.

SHA256 (256-bit)

Computing…

Hashing is one-way: you cannot recover the original text from a hash. For password storage use a slow, salted algorithm such as bcrypt or Argon2, never a plain hash like these.

How to use the Hash Generator

  1. Type or paste the text you want to hash.
  2. Pick the algorithm: MD5, SHA-1, SHA-256 or SHA-512.
  3. Toggle uppercase output if needed.
  4. Copy the digest for your checksum, comparison or record.
  5. Read the algorithm note to confirm it fits your use case.

Frequently asked questions

Which hash algorithm should I use?

SHA-256 for almost everything modern — it is the default in TLS, Git and most verification tooling. Choose SHA-512 when a system explicitly requires a larger digest, and MD5/SHA-1 only for legacy compatibility or non-security checks.

Are longer hashes more secure?

Generally yes — more bits means a vastly larger space to brute-force or collide. But MD5 is broken despite being 128 bits because of structural weaknesses, not length. Algorithm soundness matters as much as size.

What is a checksum and how do I verify one?

A checksum is a hash published alongside a file so you can confirm it downloaded intact: hash your copy and compare the digest with the publisher's. If they match exactly, the file is byte-for-byte identical — this tool provides the digest to compare.
