What is a hash function?

A hash function is a mathematical algorithm that converts an input of any size into a fixed-size string of characters. The output, known as the hash, is unique to the input text. Even a tiny change in the input will produce a completely different hash. This is essential for verifying data integrity.

Which hashing algorithm should I use?

For security-sensitive applications like password storage, SHA-256 or SHA-512 are the modern standards. MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes, but are still useful for non-security applications like file checksums.
