Generate SHA-1/256/384/512 hashes

Compute cryptographic hashes using SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. File hashing uses the browser's built-in Web Crypto API — files are processed locally and never uploaded to any server. Useful for verifying file integrity (checksums), generating content-addressable identifiers, computing digests during development, and checking downloaded file hashes against published values. Results are shown in both hexadecimal and Base64 formats.

## Questions and answers

### Are files uploaded to your server when hashing?

No. File hashing uses the Web Crypto API built into your browser — files are never uploaded or transmitted anywhere.

### Is SHA-1 still secure?

SHA-1 is considered cryptographically broken for security purposes such as digital signatures. For any security-sensitive hashing, use SHA-256 or higher.
