What this tool does
Generate a 32-character hexadecimal MD5 hash for UTF-8 text for compatibility checks with older systems, not for security.
- Output is fixed at 32 hexadecimal characters.
- Can be used for legacy system compatibility and non-adversarial consistency checking.
- Do not use MD5 to store passwords, sign secure data, or resist malicious tampering.
How to use it
- Enter text that requires compatibility verification.
- Select lowercase or uppercase output.
- Click "Generate MD5".
- Copy the digest and decide whether MD5 is appropriate for your use case.
Common uses
- Check the results with older systems that still use MD5.
- Check data consistency in non-security scenarios.
- Reproduce MD5 values in documents or test vectors.

FAQ
Is MD5 suitable for saving passwords?
Not suitable. Passwords should use a dedicated slow password hashing scheme and configure a salt value.
Can MD5 be used for secure signatures?
Not recommended. MD5 is no longer safe from modern collisions and SHA-256 or a more suitable signature algorithm should be chosen.
What should I use for security checks?
Prefer SHA-256 or SHA-512 for general content integrity checks. Password storage and digital signatures require solutions designed for those purposes.
Will the input be uploaded?
No. MD5 calculations only happen in the browser.
