Secure Hash Generator

Security & Encryption

Generate MD5, SHA-1, SHA-256, SHA-512 and other cryptographic hashes.

Input Text

What is Secure Hash Generator?

Secure Hash Generator computes cryptographic hash values for any text or file using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. Everything runs locally in your browser using the Web Crypto API, so no data is ever transmitted.

How to use Secure Hash Generator

Choose text or file mode

Click "Hash Text" to hash typed or pasted content, or "Hash File" to compute hashes for any local file.

Enter your content

Type or paste text in the textarea, or drag and drop a file onto the upload area.

Read all hash outputs

All supported algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) compute simultaneously and appear in a list.

Copy any hash

Hover over a hash row and click Copy to put that specific value on your clipboard.

Who uses Secure Hash Generator?

File integrity verification

System administrators

Compute SHA-256 checksums of downloaded software packages and compare them to the publisher's published hash to confirm the file is unmodified.

Password hashing reference

Security researchers

Generate test hashes to compare against password hashing outputs during penetration testing or security audits.

API signature debugging

Backend developers

Manually compute HMAC-style hashes to debug mismatched signatures in webhook verification and API authentication flows.

FAQ

What is the difference between MD5 and SHA-256?+

MD5 produces a 128-bit hash and is considered cryptographically broken. SHA-256 produces a 256-bit hash and is widely used in security applications. Always prefer SHA-256 or higher for security-critical use cases.

Can I hash a file?+

Yes — use the File tab to hash a file directly in your browser. The file is never uploaded; hashing runs locally.

Are these hashes reversible?+

No. Cryptographic hash functions are one-way — you cannot derive the original input from the hash output.
