Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text input.
How to Use the Hash Generator
Simply type or paste your text into the input field. All hash values are calculated automatically in real-time. You can copy any hash value with a single click.
Supported Hash Algorithms
- MD5 - 128-bit hash, 32 hex characters. Fast but not cryptographically secure.
- SHA-1 - 160-bit hash, 40 hex characters. Deprecated for security use.
- SHA-256 - 256-bit hash, 64 hex characters. Widely used and secure.
- SHA-384 - 384-bit hash, 96 hex characters. Truncated version of SHA-512.
- SHA-512 - 512-bit hash, 128 hex characters. Maximum security.
Common Use Cases
- File Integrity - Verify downloaded files match their published checksums
- Password Storage - Hash passwords before storing (use SHA-256 or better)
- Data Deduplication - Identify duplicate content by comparing hashes
- Digital Signatures - Create unique fingerprints for documents
Useful with the Base64 Encoder for binary payloads and the UUID Generator for unique identifiers.
Frequently Asked Questions
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 have known vulnerabilities and should only be used for checksums or non-security applications.
Can I reverse a hash to get the original text?
No. Hash functions are one-way by design. You cannot mathematically reverse a hash to obtain the original input. This is what makes them useful for password storage.
Is my data secure?
Yes. All hash calculations happen directly in your browser using the Web Crypto API. Your data never leaves your device and is not sent to any server.
