Frequently Asked Questions
What is a hash function?
A hash function converts data into a fixed-size string of characters. The same input always produces the same hash, but you can't reverse it to get the original data.
Which hash algorithm should I use?
SHA-256 is recommended for most uses. MD5 and SHA-1 are considered cryptographically broken. Use SHA-512 for maximum security in new applications.
Can I use MD5 for passwords?
No! Never use MD5 or SHA for passwords. Use specialized password hashing like bcrypt, argon2, or PBKDF2 which include salt and are designed to be slow.
Why do the same texts produce same hash?
This is by design - hash functions are deterministic. This property allows you to verify data integrity by comparing hashes.
Can two different inputs have same hash?
Theoretically yes (collision), but for SHA-256 and stronger, finding collisions is computationally infeasible with current technology.
How can I verify file integrity?
Generate hash of original file and compare with hash of received file. If they match, files are identical. Many downloads provide official hashes for verification.
