How to use it

  1. Enter the exact text you want to fingerprint.
  2. Calculate and copy the hexadecimal SHA-256 digest.

“abc” produces ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.

Details & limits

100,000 characters. Every space and line break matters. SHA-256 is one-way hashing, not encryption or password storage.

Why did my hash change?

Spaces, letter casing and line breaks all change the UTF-8 bytes and therefore the digest. Empty text is a valid input. A plain SHA-256 hash is unsuitable as a password storage scheme.

Hash the exact text you enter

The generator hashes UTF-8 bytes without trimming whitespace, changing line endings or normalizing Unicode. This matters when visually similar text produces different hashes. It accepts up to 100,000 input characters and returns a hexadecimal digest. SHA-256 is one-way hashing, not reversible encryption, and this tool is not a password-storage system or a file checksum uploader.
