Question 1

What is the File Hash Checker and what does it do?

Accepted Answer

The File Hash Checker is a security tool designed to compute cryptographic hashes like SHA-256 and SHA-512 to verify the integrity of your files. By generating a unique digital fingerprint, it allows you to ensure that a file has not been altered or corrupted during a download or transfer.

Question 2

How do I use this tool to verify a file's integrity?

Accepted Answer

To use the tool, simply drag and drop your file into the browser or click to select one from your device. Once the hash is generated, you can paste an expected hash into the verification field to instantly see if the checksums match.

Question 3

Is my data safe when using the File Hash Checker?

Accepted Answer

Yes, your data is completely secure because all computations happen locally on your device using the Web Crypto API. No file is ever uploaded to a server, ensuring your sensitive information never leaves your browser.

Question 4

Which cryptographic hash algorithms are supported?

Accepted Answer

This tool supports a variety of standard cryptographic algorithms including SHA-1, SHA-256, SHA-384, and SHA-512. These options allow you to choose the specific level of security or compatibility required for your file verification needs.

Question 5

Is there a cost to use the File Hash Checker?

Accepted Answer

This tool is entirely free to use and does not require a paid subscription. Anonymous users can perform up to 200 checks, while authenticated users have a higher rate limit of 1,000 requests.

Question 6

What are the browser requirements for this tool?

Accepted Answer

The tool works in any modern web browser that supports the Web Crypto API. Because it processes files locally, it is compatible with files of any size and type without requiring additional software installations.

Question 7

Are there any limitations on the file types I can check?

Accepted Answer

There are no specific limitations on file types; the tool can process any file format you provide. Since the processing is done via your browser's local resources, it can handle large files efficiently without the need for an internet upload.
