Important
MD5 is cryptographically broken. Never use it for passwords, signatures, certificates or adversarial integrity checks.
How to use this md5 hash generator
- Confirm the legacy format actually requires MD5.
- Enter the exact UTF-8 text and select Generate MD5 digest.
- Copy the checksum without treating it as secure proof.
MD5 output and risk
MD5 processes bytes into a 128-bit digest displayed as 32 hexadecimal characters. Collision attacks make it unsuitable when an attacker could influence either input.
| Input | MD5 result |
|---|---|
hello | 5d41402abc4b2a76b9719d911017c592 |
| Output length | 32 hex characters |
Worked example
Entering hello reproduces the published MD5 test value above. That is useful for compatibility, but it is not evidence that another malicious file or message cannot share the digest.
MD5 questions
Is MD5 secure?
No. It is broken for collision-resistant security uses.
Can I use MD5 for passwords?
No. Use a unique salt with bcrypt, Argon2, scrypt or PBKDF2.
When is MD5 still encountered?
Mostly in legacy formats and non-adversarial compatibility checks.
