Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes online. Hash strings or files with the Web Crypto API — no upload, 100% in-browser. Free hash generator.
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.
Frequently Asked Questions
- 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.
- Is this tool free to use?
- Yes, all tools on Here Be Tools are completely free with no signup or account required.
- Is my data sent to a server?
- No. All processing happens locally in your browser. No data you enter is ever transmitted to any server.
