How to use it

  1. 1

    Enter text.

  2. 2

    Select a SHA algorithm.

  3. 3

    Generate and copy the hexadecimal digest.

02

What the tool can do

  • SHA-256, SHA-384, and SHA-512.
  • UTF-8 encoding for the input string.
  • Lowercase hexadecimal output.
03

Common use cases

  • Comparing checksums for text.
  • Preparing a test digest during development.
  • Checking whether a string value changed.
04

How it works inside

The same text and algorithm produce the same digest.

Even a small input change substantially changes the output.

Questions and answers

Can the text be recovered from the hash?

No. A cryptographic hash is designed as a one-way transformation.

Can it hash a file?

No. The current version accepts text only.
