Can a hash be decrypted back into the original data?
No. A cryptographic hash is designed as a one-way transformation. The practical purpose is to compare or verify digests, not to recover the original input.
How to Use Cryptographic Hash Generator
Step 1: Enter Text or File
Type string or select any file.
Step 2: Generate Hashes
The browser's native crypto.subtle engine computes multi-digest hashes.
Step 3: Copy Hashes
Copy SHA-256, SHA-512, or SHA-1 strings with one click.

Frequently Asked Questions
Why would I use SHA-256 instead of a generic hash option?
SHA-256 is a specific, widely used cryptographic hash algorithm. When a software release, API, or security workflow specifies SHA-256, use that exact algorithm rather than choosing a different digest format.
Does a matching hash prove a file is safe?
No. A matching hash shows that the compared inputs produced the same digest. It does not by itself establish that the source is trustworthy or that the file is free of malicious content.
