Frequently asked questions
Which hash algorithm should I use?
SHA-256 for most security applications. SHA-512 for highest security. MD5/SHA-1 are cryptographically broken — use only for non-security checksums.
Can hashes be reversed?
No. Hashing is a one-way function. Given a hash, you cannot mathematically recover the original input.
