Is MD5 secure for passwords?

No. MD5 is cryptographically broken and should never be used to hash passwords. Use bcrypt, scrypt, or Argon2 for passwords. MD5 is still useful for checksums and non-security purposes.

Does the hash change if I add a space?

Yes. A single character difference completely changes the hash output. This is the "avalanche effect" — a fundamental property of cryptographic hash functions.

Hash Generator

Generates cryptographic hashes from text input using the browser's native Web Crypto API. Supports MD5 (via JS implementation), SHA-1, SHA-256, SHA-384, and SHA-512. Results are shown in lowercase hex. Useful for checksums, password hashing demos, data integrity verification, and learning about hash functions.
