About Hash Algorithms
  • SHA256: 256-bit secure hash, widely used for cryptocurrencies and SSL certificates
  • MD5: 128-bit hash, fast but cryptographically broken, still used for checksums
  • SHA512: 512-bit extremely secure hash for high-security applications
  • SHA1: 160-bit hash, deprecated for security but still used in legacy systems
  • SHA384: 384-bit truncated version of SHA512, good balance of security and speed

Hash Security Guide
  • Cryptographic Strength: SHA256 and SHA512 are secure for passwords and sensitive data
  • Collision Resistance: MD5 and SHA1 have known collisions - avoid for security
  • Password Storage: Always use salted hashes with algorithms like SHA256
  • File Integrity: Use SHA256 for checksums to verify file downloads
  • Performance: MD5 is fastest, SHA512 provides best security at cost of speed

About Hash Generator

About Hash Generator

Our Hash Generator is a powerful cryptographic tool that creates unique fixed-size hashes from any input data using industry-standard algorithms. Hashes are one-way functions that are essential for data integrity verification, password storage, digital signatures, and blockchain technology.

The generator supports multiple hash algorithms with various output formats and encoding options. It can process both text and files, providing detailed hash information and verification capabilities. All processing happens client-side for maximum security and privacy.

Perfect for developers, security professionals, system administrators, and anyone working with data integrity, authentication systems, or cryptographic applications. The tool provides enterprise-grade hash generation with an intuitive interface.

How to Use

  1. Select the hash algorithm: SHA256 (recommended), MD5, SHA512, SHA1, or SHA384.
  2. Enter text in the input box or upload a file using drag & drop or file browser.
  3. Configure hash options like output format (HEX/Base64), encoding, and HMAC mode.
  4. Click "Generate Hash" to create the cryptographic hash of your input.
  5. Review the generated hash and detailed hash information.
  6. Use the verification feature to compare hashes and ensure data integrity.
  7. Copy, verify, or share your hash results as needed.

Security Tip: For password storage, always use strong algorithms like SHA256 with salt. For file integrity verification, SHA256 provides excellent collision resistance. Never use MD5 or SHA1 for security-critical applications.

Frequently Asked Questions

Is this Hash Generator free to use?

Yes, our Hash Generator is completely free with no registration required. You can generate unlimited hashes without any limitations or watermarks.

Are my data and files secure?

Absolutely! All hash generation happens locally in your browser. Your text and files are never uploaded to any server, ensuring complete privacy and security.

What is the maximum file size I can hash?

You can hash files up to 100MB in size. For text input, there's virtually no limit. The tool processes large files efficiently in your browser.

What's the difference between SHA256 and MD5?

SHA256 is a 256-bit secure hash algorithm used for security-critical applications. MD5 is a 128-bit hash that's faster but cryptographically broken and should only be used for non-security checksums.

Can I generate hashes for binary files?

Yes! Our tool supports any file type including images, videos, executables, documents, and archives. Simply upload the file and generate its hash.

What is HMAC mode?

HMAC (Hash-based Message Authentication Code) adds an extra layer of security by combining your input with a secret key. This is used for message authentication and API security.

Which hash algorithm should I use?

Use SHA256 for general security purposes. Use SHA512 for maximum security. Use MD5 only for non-security checksums. Never use MD5 or SHA1 for passwords or sensitive data.

How do I verify if two hashes match?

Use the "Verify Hash" feature. Paste the hash you want to compare, and the tool will tell you if it matches your generated hash. This is perfect for verifying file downloads.

Can I generate hashes offline?

Yes! Once the page loads, you can use the tool completely offline. All hash calculations are performed locally in your browser using JavaScript.

What output formats are available?

You can output hashes in Hexadecimal (HEX), Base64, or Binary format. HEX is the most common format and is selected by default.
