MD5 Hash Generator
Generate MD5 hashes from any text. Useful for checksums, file verification, and data integrity checks. Fast, secure, and client-side processing.
About MD5 Hash Algorithm
MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It's commonly used for checksums, file verification, and data integrity checks, though not recommended for cryptographic security.
Key Features
🔢 Fixed Length Output
Always produces 128-bit (16 bytes) hash, regardless of input size
⚡ Fast Computation
Very quick to compute, making it ideal for checksums and data verification
🎯 Deterministic
Same input always produces the same hash output
🔄 Avalanche Effect
Small change in input creates completely different hash
Common Use Cases
- ✓File Verification: Check if downloaded files are intact and unmodified
- ✓Data Integrity: Verify data hasn't been corrupted during transfer
- ✓Checksums: Quick file identification and duplicate detection
- ✓Database Keys: Generate unique identifiers from data
- ✓Cache Keys: Create cache identifiers for web applications
- ✓ETags: HTTP cache validation headers

Example MD5 Hashes
Security Considerations
Not Cryptographically Secure
MD5 is NOT recommended for security-critical applications like password storage or digital signatures due to known collision vulnerabilities.
- • ❌ Don't use for password hashing (use bcrypt, Argon2, or scrypt instead)
- • ❌ Don't use for digital signatures (use SHA-256 or SHA-3 instead)
- • ❌ Don't use for SSL/TLS certificates
- • ✓ OK for checksums and non-security data integrity
- • ✓ OK for cache keys and ETags
- • ✓ OK for file deduplication
MD5 vs Other Hash Functions
| Algorithm | Hash Size | Speed | Security | Best For |
|---|---|---|---|---|
| MD5 | 128 bit | Very Fast | Broken | Checksums, cache keys |
| SHA-1 | 160 bit | Fast | Deprecated | Legacy systems only |
| SHA-256 | 256 bit | Fast | Secure | Security, signatures |
| SHA-512 | 512 bit | Moderate | Very Secure | High security needs |
| bcrypt | Variable | Slow (by design) | Very Secure | Password hashing |
Frequently Asked Questions
Can MD5 be reversed or decrypted?
No, MD5 is a one-way hash function and cannot be reversed. However, for common inputs (like weak passwords), the hash can be looked up in rainbow tables. This is why MD5 shouldn't be used for passwords.
What are MD5 collisions?
Collisions occur when two different inputs produce the same MD5 hash. Researchers have demonstrated practical collision attacks, making MD5 unsuitable for security applications where collision resistance is critical.
Is MD5 still useful?
Yes, for non-security purposes! MD5 is still widely used for checksums, file verification, cache keys, ETags, and duplicate detection where cryptographic security isn't required.
What should I use instead of MD5 for passwords?
Use bcrypt, Argon2, scrypt, or PBKDF2 for password hashing. These are specifically designed for passwords with features like salting and adjustable work factors.
Why are some MD5 hashes different for the same input?
They shouldn't be! MD5 is deterministic - same input always produces the same hash. If you see different hashes, the inputs are different (even by one character, whitespace, or encoding).
