Frequently Asked Questions
A hash function is a mathematical algorithm that transforms input data into a fixed-size string of characters. The output (hash) is unique to the input and cannot be reversed to obtain the original data.
For modern applications, SHA-256 or higher is recommended. MD5 and SHA1 are considered cryptographically broken and should only be used for non-security purposes like checksums.
While these hash functions can be used as part of a password system, modern password hashing should use specialized algorithms like bcrypt, Argon2, or PBKDF2 with proper salting.
