Tool ID: file-checksum. Requested language: ng. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

File checksum verifier calculates a checksum of a file from its exact bytes, using SHA-256, SHA-384, SHA-512 or MD5. The digest can be shown as lowercase hex, uppercase hex or Base64, so you can compare it with the value a download page publishes. Files must be smaller than 50 MB.

## Supported tasks (en)

Calculate a checksum of a file on your device.

## Steps (en)

1. Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
2. Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
3. Run file checksum verifier, review the output, then use the available copy or download controls.

## Settings

- Algorithm (en; key: algorithm; type: select): SHA-256 [en], SHA-384 [en], SHA-512 [en], MD5 [en]
- Digest format (en; key: digestFormat; type: select): hex [en], HEX [en], base64 [en]

## Limitations (en)

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.

## Example input

```text
Hello ToolCabana

## Questions (en)

### How do I verify a downloaded file checksum?

Choose the file, pick the algorithm the publisher used, such as SHA-256, and run the tool. Compare the resulting digest with the published value; any difference means the bytes are not identical.

### Which checksum algorithms are supported?

You can choose SHA-256, SHA-384, SHA-512 or MD5. MD5 is offered for legacy checksums only and is not suitable for cryptographic security.

### Does the file checksum check a digital signature?

No. It computes a digest of the file bytes only. It does not read the file as text and does not validate any signature or certificate attached to it.

### Where is my input processed?

This operation processes its source in your browser. Copy and download are explicit actions; source input is not saved in an account or history.

### What are the input limits?

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.
