About Hash Generator

Calculate a SHA-256, SHA-384 or SHA-512 digest of entered text locally, useful for verifying content against another system.

What the result contains

A lowercase hexadecimal SHA-256, SHA-384 or SHA-512 digest of the entered UTF-8 text.

Accepted input

  • PLAIN
  • TXT

How to use Hash Generator

  1. Enter the text you want to hash.
  2. Choose the algorithm: SHA-256, SHA-384 or SHA-512.
  3. Run the calculation and copy the hexadecimal digest.
  4. Compare it against the other system's hash, checking whitespace and encoding if they differ.
Practical example

Calculate a SHA-256 checksum for a known text payload and compare it with another system.

Check your result before using it

Check the selected algorithm and ensure the input includes exactly the intended spaces and line endings. Even a final newline changes a digest. To compare against a published checksum, you must hash the same bytes with the same algorithm; hashing the displayed filename does not verify the file. A digest also does not prove who created the data, and a plain fast hash is not suitable password storage.

When to use Hash Generator

  • Calculate a checksum for a text payload to compare against another system
  • Verify that two copies of a value are byte-for-byte identical
  • Generate a reference hash for a piece of sample text

Important limitations

  • A plain hash is not suitable for storing passwords; password storage requires a salted, slow password-hashing algorithm.
  • Text encoding and line endings must match exactly for hashes to match.

Troubleshooting Hash Generator

The digest differs from another tool

Check the selected algorithm, whitespace, line endings and whether the other tool hashed a file's raw bytes instead of visible text.
