❓ FAQ
Is MD5 encryption reversible?
No. MD5 is a one-way hash function. You cannot decrypt an MD5 hash back to the original text. This tool verifies that text/files match a known MD5 hash.
How do I verify an MD5 checksum?
Switch to "Decrypt" mode, enter your file or text, paste the known MD5 hash, and click Convert. The tool will show if they match.
Can I hash files?
Yes! Upload any file and the tool will compute its MD5 hash. This is useful for verifying file integrity.
Is MD5 safe for passwords?
No. MD5 is cryptographically broken and should not be used for password hashing. Use bcrypt, scrypt, or Argon2 instead. MD5 is suitable for checksums only.
What's the difference between uppercase and lowercase?
MD5 hashes are hexadecimal. Uppercase and lowercase represent the same hash value. Enable "Uppercase hash" if your verification source uses uppercase.
Does this tool send my data to a server?
No. All MD5 hashing happens in your browser. Your data never leaves your device.
Can I use this offline?
Yes! Once the page loads, all processing happens in your browser without internet connection.
What is MD5 used for today?
MD5 is primarily used for checksums to verify file integrity and detect accidental corruption. It should not be used for security purposes like password hashing.
