What is a hash function?

A hash function converts input data into a fixed-size string of characters, which is typically used for data integrity verification and password storage.

Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for cryptographic purposes but useful for checksums.
