Cryptographic Hash Generator
Enter any text and generate MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously. SHA-1, SHA-256, and SHA-512 use the browser's hardware-acceleratedcrypto.subtleWeb Crypto API. No data is sent to any server.
Frequently Asked Questions
- What hash algorithms are supported?
- The tool supports MD5, SHA-1, SHA-256, and SHA-512. SHA-256 and SHA-512 use the browser's native Web Crypto API. MD5 uses a pure JavaScript implementation since it is not in the Web Crypto standard.
- Is my data safe?
- Yes. All hashing is performed locally in your browser. Your input text is never sent to any server. SHA-256 and SHA-512 use the browser's hardware-accelerated crypto.subtle API.
- What is a hash used for?
- Hashes are used to verify file integrity, store passwords securely (with a proper algorithm like bcrypt for passwords), generate checksums, and create digital fingerprints of data.
- Should I use MD5 or SHA-1 for security?
- No. MD5 and SHA-1 are considered cryptographically broken for security purposes. Use SHA-256 or SHA-512 for anything security-sensitive. MD5 and SHA-1 are still useful for non-security purposes like checksums.
- Can I hash a file with this tool?
- This tool hashes text input. For file hashing, you would need to read the file as a binary ArrayBuffer. File hashing support may be added in a future update.
