Generate MD5 hashes for text and files with verification support

MD5 Hash Generator

MD5 Hash Generator Tool

Generate MD5 hashes for text and files directly in your browser. MD5 (Message Digest Algorithm 5) produces a 128-bit hash value commonly used for checksums and data integrity verification, though it's no longer recommended for security purposes.

Supports both text input and file uploads up to 10MB. The tool generates MD5 hashes instantly using client-side JavaScript, includes hash verification to compare generated hashes against expected values, and displays results in standard hexadecimal format. All processing happens in your browser without sending data to servers.

Useful for verifying file integrity during downloads, creating checksums for file comparison, debugging and development purposes, and legacy system compatibility. Note: MD5 should not be used for password hashing or security-critical applications due to known vulnerabilities.

Instant hash generation with no waiting, complete privacy as all processing is local, file and text support in one tool, hash comparison feature for verification, and no file size restrictions beyond browser memory limits.

MD5 Generator FAQ

Is MD5 secure for passwords?

No. MD5 is cryptographically broken and should never be used for password hashing or security-critical applications. Use SHA-256, SHA-512, or bcrypt for password storage instead.

What is MD5 used for?

MD5 is still used for non-security purposes like file integrity checksums, detecting duplicate files, and verifying data transmission. However, for any security application, use SHA-256 or SHA-512.

Why do I need to verify MD5 hashes?

Hash verification ensures file integrity. When downloading files, you can compare the generated MD5 hash with the one provided by the source to confirm the file wasn't corrupted or tampered with during transmission.

Can two different inputs produce the same MD5 hash?

Yes, this is called a collision. MD5 is vulnerable to collision attacks, which is why it's not recommended for security. Attackers can create different inputs that produce the same MD5 hash.

What's the maximum file size I can hash?

The tool supports files up to 10MB for browser performance reasons. For larger files, the hash generation might be slow or fail due to browser memory limitations.

Pro Tips

  • Use SHA-256 or SHA-512 for security applications
  • MD5 is fine for checksums and duplicate detection
  • Compare hashes in lowercase to avoid case-sensitivity issues
  • Keep hash values in version control for file verification
  • For security, always use cryptographically secure algorithms
