Free Hash Checker — Verify File & Text Integrity
Our free hash checker computes and compares MD5, SHA-1, SHA-256 and SHA-512 hashes. Use it to verify downloaded files have not been tampered with, or confirm two files are identical without opening them.
🔐 Verify Downloads
Compare file hash against publisher checksum.
📁 File Hashing
Generate SHA-256 for any file without uploading it.
📝 Text Hash Compare
Check if text matches a known hash value.
✅ Instant Match
Green checkmark when hashes match, red when they differ.
How to Use — Step by Step
1
Generate the hash
Paste text or upload a file. All four hashes computed instantly.
2
Enter the expected hash
Paste the hash published by the software provider.
3
Compare
Green = match (file is genuine). Red = mismatch (file may be corrupted or tampered).
Frequently Asked Questions
What does matching hashes mean?
The file is exactly as the provider intended — not corrupted during download, not modified by malware, not tampered with.
Which algorithm to use for verification?
SHA-256 is recommended. MD5 is still common but has known collision vulnerabilities. Use whatever the provider lists.
Can I verify a password hash?
You can compute a plaintext hash and compare to a stored hash. Modern passwords use salt though — simple comparison will fail without the salt.
If hashes do not match, what should I do?
Download again from the official source. If hashes consistently do not match, the file may have been tampered with — do not run it.
What is a checksum?
A hash used to verify file integrity. Even one bit change produces a completely different hash.
