MD5 Generator

Generate MD5 hashes from any text string instantly in your browser. Useful for file integrity checksums, data deduplication, and cache key generation. Note: MD5 is not secure for password hashing — use bcrypt or SHA-256 for passwords.

⚠️ MD5 is not secure for passwords. Use bcrypt or SHA-256 for password hashing. MD5 is safe for file checksums.

Frequently Asked Questions

Is MD5 secure for storing passwords?▼
No. MD5 is cryptographically broken for password hashing. A GPU can compute billions of MD5 hashes per second, making password databases vulnerable. Use bcrypt, Argon2, or PBKDF2 for passwords.
What is MD5 still useful for?▼
File integrity verification (checksums), detecting duplicate files by hash, generating cache keys, non-security deduplication, and legacy system compatibility where security is not a concern.
Is my text sent to a server when I generate an MD5 hash?▼
No. MD5 is computed in your browser using a pure-JavaScript implementation. Nothing is transmitted.
What does an MD5 hash look like?▼
An MD5 hash is always exactly 32 hexadecimal characters, for example: 5d41402abc4b2a76b9719d911017c592.
Can two different texts produce the same MD5 hash?▼
Theoretically yes (collisions), which is one reason MD5 is not secure for cryptographic purposes. However, accidental collisions are extremely rare for typical use cases like checksums.
