About Hash Generator

Generate cryptographic hash values from text or files. Hash functions are one-way algorithms that convert input data into fixed-size strings of bytes, commonly used for data integrity verification, password storage, and digital signatures. This free online hash generator supports 11 algorithms (MD5, SHA-1, SHA-2 family, SHA-3 family, and RIPEMD-160) with instant, client-side processing. Hash both text and files, select multiple algorithms simultaneously, and compare results side-by-side.

SHA-2 Family (Recommended):

  • SHA-256 (256-bit): Industry standard, cryptographically secure. Recommended for most use cases including certificates, blockchain, and security.
  • SHA-512 (512-bit): Maximum security variant of SHA-2 family. Ideal for high-security applications and large data hashing.
  • SHA-384 (384-bit): Truncated SHA-512 variant. Good balance between security and performance for sensitive data.
  • SHA-224 (224-bit): Truncated SHA-256 variant. Used in applications requiring shorter hash outputs.

SHA-3 Family (Modern Standard):

  • SHA3-512 (512-bit): Latest NIST standard (Keccak). More resistant to certain attacks than SHA-2. Excellent for new applications.
  • SHA3-384 (384-bit): SHA-3 variant offering strong security with moderate hash length.
  • SHA3-256 (256-bit): Modern alternative to SHA-256. Based on different mathematical principles for added security diversity.
  • SHA3-224 (224-bit): Shortest SHA-3 variant, suitable for applications requiring compact hashes.

Legacy & Specialized:

  • SHA-1 (160-bit): Deprecated for cryptographic use due to collision vulnerabilities. Still used in git and some legacy systems.
  • MD5 (128-bit): Completely broken for security purposes. Use only for non-cryptographic checksums and legacy compatibility.
  • RIPEMD-160 (160-bit): Used primarily in Bitcoin address generation and other cryptocurrency applications.

Common Use Cases:

  • File Integrity: Verify file integrity and detect tampering
  • Checksums: Generate checksums for data validation
  • Content IDs: Create unique identifiers from content
  • Password Hashing: Hash passwords before storage (use with proper salt)
  • Digital Signatures: Generate hashes for digital signatures and certificates
  • Blockchain: Hash generation for blockchain and cryptocurrency operations
  • Git Commits: Generate commit hashes for version control

Key Features:

  • 11 Hash Algorithms: SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512), SHA-3 family (SHA3-224, SHA3-256, SHA3-384, SHA3-512), plus MD5, SHA-1, and RIPEMD-160
  • Multiple Algorithm Selection: Select and compare multiple hash algorithms simultaneously - see all outputs side-by-side
  • Text & File Hashing: Hash both text input and files (any file type) with the same algorithms
  • Drag & Drop Support: Easily drop files onto the drop zone for quick hashing
  • Image Preview: Automatically displays thumbnail preview for image files
  • Real-time Generation: Hash updates instantly as you type or when files are selected
  • Modern & Legacy Support: From cutting-edge SHA-3 to legacy MD5 compatibility
  • One-Click Copy: Copy individual hash outputs to clipboard with visual feedback for each algorithm
  • Client-side Processing: Complete privacy - all hashing happens in your browser, no data sent to servers
  • No Limits: No file size or text length restrictions
  • No Sign-up Required: Free to use without registration

Security Notes:

  • MD5 and SHA-1 are considered broken for cryptographic purposes due to collision vulnerabilities. Use only for non-security checksums.
  • Use SHA-256 or higher for security-critical applications like password storage, digital signatures, and data integrity verification.
  • Hash functions are one-way - you cannot reverse a hash to get the original input (this is by design for security).
  • Always use proper salting and key derivation functions (like bcrypt, scrypt, or PBKDF2) for password hashing in production systems.
  • All hashing is performed client-side in your browser - no data is sent to any server, ensuring complete privacy and security.
