Compare Hashes

Paste two hashes to check if they match

Algorithm	Output	Security	Use Case
MD5	32 hex chars	Broken	Checksums only
SHA-1	40 hex chars	Deprecated	Legacy systems
SHA-256	64 hex chars	Secure	General purpose
SHA-384	96 hex chars	Secure	High security
SHA-512	128 hex chars	Secure	High security

Note: For password hashing, use specialized algorithms like bcrypt, scrypt, or Argon2 instead of these general-purpose hash functions.

Generate cryptographic hashes for text and files instantly. Support for MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. Perfect for file integrity verification.

All hashing happens locally in your browser. Your data is never uploaded to any server.

How to Use This Tool

1 Enter text or upload a file to hash
2 See all hash algorithms calculated automatically
3 Copy the hash you need
4 Use the compare tool to verify two hashes match
5 Choose SHA-256 or SHA-512 for security-critical uses

Use Cases

File Integrity

Verify downloaded files match the expected hash to ensure no corruption or tampering.

Checksums

Generate checksums for software releases and file distributions.

Deduplication

Identify duplicate files by comparing their hash values.

Cache Keys

Create consistent cache keys based on content hashes.

Frequently Asked Questions

Which hash algorithm should I use?

Use SHA-256 for most purposes. MD5 and SHA-1 are broken for security but fine for checksums. Use SHA-512 for highest security requirements.

Is MD5 safe to use?

MD5 is cryptographically broken and should not be used for security. It's still useful for non-security checksums like verifying file transfers.

Can hashes be reversed?

Hash functions are one-way by design. You cannot reverse a hash to get the original data. That's what makes them useful for password storage.

Why are my file hashes different on different systems?

Ensure you're comparing the exact same file. Text file line endings (Windows vs Unix) or encoding differences will produce different hashes.

Should I use this for password hashing?

No. For passwords, use specialized algorithms like bcrypt, scrypt, or Argon2 that include salting and are designed to be slow to prevent brute-force attacks.
