Frequently Asked Questions
What is a hash function?
A hash function takes input data and produces a fixed-size string of characters. The same input always produces the same hash, but even a small change in input produces a completely different hash.
Which hash algorithm should I use?
SHA-256 is recommended for most use cases as it's secure and widely supported. SHA-512 is more secure but produces longer hashes. MD5 and SHA-1 are deprecated and should not be used for security purposes.
Are hashes reversible?
No. Hash functions are one-way - you cannot determine the original input from the hash. This is why they're used for password storage and data integrity verification.
