Security and developer tool

Online hash generator and checksum tool

Generate a hexadecimal digest from pasted text or a local file. Aegis supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 and performs the core hashing work in your browser.

MD5 and SHA-1 are included for compatibility checks only. Do not use them for password storage or digital signatures.

How to calculate a checksum

  1. Choose a source. Paste text or switch to the local-file option.
  2. Select an algorithm. Use SHA-256 or another supported SHA algorithm for modern integrity checks; choose legacy algorithms only when a system requires them.
  3. Compare or export. Copy the digest or download it after the checksum is calculated.

Supported hash features

  • Text input encoded as UTF-8 before hashing.
  • Local file hashing with a responsive size limit.
  • MD5, SHA-1, SHA-256, SHA-384, and SHA-512 output.
  • Input-size and digest-size details.
  • Copy and download controls for the current checksum.

Hash generator FAQ

Common questions

Can I hash a file?

Yes. Switch the source to Local file and choose a file from your device. The frontend reads it in the browser before calculating the digest.

Which hash algorithm should I choose?

Use the algorithm required by the system or publisher you are checking. SHA-256 is a common modern general-purpose choice; MD5 and SHA-1 are marked legacy in the tool.

Is a checksum the same as encryption?

No. A hash is a one-way digest used to compare data; it is not a reversible encryption method.

Does Aegis upload the text or file?

The core hash calculation runs locally in the browser. The tool does not need to upload the source material to calculate a digest.
