• MD5: 128-bit hash (not recommended for security)
• SHA-256: 256-bit hash (most widely used)
• SHA-512: 512-bit hash (higher security)
🔒 What is Hash Generator?
A hash function is a one-way function that converts data of any length into a fixed-length hash value. The same input always produces the same hash, but recovering the original from the hash is impossible. It plays a critical role in file integrity verification, password storage, digital signatures, and blockchain. This tool supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms.
📊 Hash Algorithm Comparison
| Algorithm | Output Length | Security | Use Case |
|---|---|---|---|
| MD5 | 128bit (32 chars) | Weak | Checksums (non-security) |
| SHA-1 | 160bit (40 chars) | Deprecated | Legacy compatibility |
| SHA-256 | 256bit (64 chars) | Secure | General purpose (recommended) |
| SHA-384 | 384bit (96 chars) | Secure | High security |
| SHA-512 | 512bit (128 chars) | Secure | Maximum security |
Frequently Asked Questions
Why is MD5 considered insecure?▼
Collision attacks were discovered in 2004, meaning two different inputs can produce the same hash. Use MD5 only for non-security purposes like file checksums.
Which hash should I use for passwords?▼
Use dedicated password hashing functions like bcrypt, scrypt, or Argon2 instead of general hash functions. These are intentionally slow to resist brute-force attacks.
Will the same text produce the same hash on different computers?▼
Yes, the same algorithm and input always produce identical hash values regardless of the platform. This property makes hashing useful for file integrity verification.
What is Hash Generator?
Generate cryptographic hashes including MD5, SHA-1, SHA-256, and SHA-512 from any text input. Useful for password hashing, file integrity verification, and checksums.
