Cryptographic Hash Generator (SHA-1, SHA-256, SHA-512)

Calculate text cryptographic digests instantly inside your browser.

Includes
  • SHA-1, SHA-256, SHA-384, and SHA-512
  • Hash recalculated on every change
  • Lowercase hexadecimal output
  • Character, byte, and line count
  • One-click hash copy
Real-time hash

Generate SHA hashes and compare results quickly

Type some content, choose the algorithm, and follow the hash in real time to check integrity, compare values, or document a process.

The hash changes completely when any character of the input changes.

Type some content to generate the hash.

Choose the algorithm required by the system you will compare the result with.
Generated hashSHA-256
The hash will appear here once the input is valid.
SHA-1

Legacy; use it only for compatibility, not in new sensitive scenarios.

SHA-256

The most common choice for integrity and current checks.

SHA-384

Intermediate version, with a longer output than SHA-256.

SHA-512

Longest output, for systems that require this format.

Who it is for

Check whether content changed without comparing it by hand

The hash generator is for anyone who needs a short, repeatable fingerprint of a text: developers, security students, and people checking data integrity.

  • Compare two texts by their hash instead of reading line by line.
  • Check a value published by another system from the same text.
  • Study how SHA-1 and the SHA-2 family react to small changes.
Instructions

How to generate a hash

  1. 1. Type or paste the content into the input field.
  2. 2. Choose the algorithm: SHA-1, SHA-256, SHA-384, or SHA-512.
  3. 3. Watch the hash, which is recalculated on every change.
  4. 4. Copy the result and compare it with the expected value.
How it works

Same text, same hash; one extra character, a different hash

The text is converted to UTF-8 bytes and processed by the browser's native cryptography. The result is shown in lowercase hexadecimal.

SHA-1

Produces 40 hexadecimal characters.

It is considered legacy: use it only for compatibility with older systems.

SHA-256

Produces 64 hexadecimal characters.

It is the tool's default and the most common choice in current checks.

SHA-384 and SHA-512

Produce 96 and 128 hexadecimal characters.

They offer longer outputs when the target system requires those formats.

Verifiable example

SHA-256 of the word abc

With SHA-256 and the input abc, in lowercase and with no spaces or line break, the result is always the same.

Input
abc
SHA-256

A trailing space or line break changes the hash completely. Check the input when values do not match.

Limits

A hash is not encryption

A hash is a one-way function: there is no button to get the original text back.

  • MD5 and other algorithms outside the list are not available.
  • The tool hashes text; it does not read files.
  • A plain hash is not suitable for storing passwords: login systems use dedicated functions with salt and configurable cost.
Caution

Avoid real sensitive data

The calculation happens in the browser, but real passwords and tokens should not be pasted into any online tool when an example does the job.

FAQ

Frequently asked questions

Is a hash reversible encryption?

No. A hash creates a fixed-size fingerprint and should not be used to hide text that must be recovered. Use security practices designed for the specific password or sensitive-data case.
