How It Works

1

Select Algorithm

Choose from legacy standards like MD5 or modern, high-security algorithms like SHA-256 and SHA-512 depending on your requirements.

2

Cryptographic Digesting

Using the browser's native Web Crypto API, we perform a series of complex mathematical transformations on your input to create a unique bit-fingerprint.

3

Hexadecimal Output

The resulting binary digest is converted into a standard hexadecimal string, providing a fixed-length representation of your data.

Common Use Cases

File Integrity Verification

Generate a hash for your downloads or scripts to ensure they haven't been modified or corrupted during a transfer.

Package Checksums

Create the SHA-256 or MD5 hashes required when publishing packages to registries like NPM or internal repositories.

Developer Debugging

Compare two data blocks by hashing them; if the hashes match, the data is guaranteed to be identical without needing a char-by-char comparison.

100% Private & Secure

All processing happens directly in your browser. Your data never leaves your device — we don't upload, store, or have access to any of your content.

Instant & Offline-Ready

No server roundtrips means instant results. Once this page is loaded, the tool works even without an internet connection.

Frequently Asked Questions

Is hashing the same as encryption?

No. Encryption is two-way (you can decrypt it), while hashing is a 'one-way' function. You cannot 'de-hash' a string back to its original plain text.

Which algorithm is the most secure?

For security-sensitive tasks, use SHA-256, SHA-384, or SHA-512. MD5 and SHA-1 are suitable for simple checksums but are not recommended for cryptographic security.

Why is MD5 available if it's 'broken'?

MD5 is still widely used in legacy systems and for simple file verification (checksums) where speed is prioritized over cryptographic resilience.
