Frequently Asked Questions
Which hash algorithm should I use?
SHA-256 for most purposes. SHA-512 for extra security. Never use MD5 or SHA-1 for passwords or security — they have known vulnerabilities.
Are hash functions reversible?
No. Hashes are one-way functions. You cannot recover the original input from a hash. This is why they are used for password storage.
