Frequently Asked Questions

What is a cryptographic hash?

A cryptographic hash function takes input data and produces a fixed-size string (hash). The same input always produces the same hash. Even a small input change produces a completely different hash.

Which hash algorithm should I use?

Use SHA-256 or SHA-512 for general security purposes. SHA-1 is considered weak and should not be used for security-sensitive applications. MD5 is not listed as it is cryptographically broken.

What is hashing used for?

Common uses include: password storage (with salt), file integrity verification (checksums), digital signatures, data deduplication, and content-addressed storage.

Are these hashes secure?

SHA-256 and SHA-512 are currently secure for most applications. Hashes are one-way — you cannot reverse them to get the original input.
