About Cryptographic Hashes

A cryptographic hash function converts data of any size into a fixed-size string of characters. The output is unique to each input—even a small change produces a completely different hash.

Hash Algorithms

MD5 (128-bit): Fast but no longer cryptographically secure. Still used for checksums.
SHA-1 (160-bit): Deprecated for security purposes. Occasionally used for non-security checksums.
SHA-256 (256-bit): Part of SHA-2 family. Widely used and considered secure.
SHA-384 (384-bit): Truncated version of SHA-512. Provides extra security margin.
SHA-512 (512-bit): Highest security in SHA-2 family. Recommended for sensitive applications.

Common Use Cases

File Integrity: Verify downloaded files haven't been modified
Password Storage: Store passwords securely (with salt)
Digital Signatures: Verify document authenticity
Data Deduplication: Identify duplicate files

Frequently Asked Questions

Which hash algorithm should I use? +

For security-sensitive applications, use SHA-256 or SHA-512. For simple file checksums where security isn't critical, MD5 or SHA-1 may be acceptable due to their speed.

Can I reverse a hash to get the original data? +

No. Cryptographic hashes are one-way functions. You cannot reverse them to get the original input. This is by design and is what makes them useful for security.

Is my data secure? +

Yes! All hash calculations happen entirely in your browser using the Web Crypto API. No data is ever sent to any server.
