About Hash Functions
A hash function takes input data and produces a fixed-size string of characters. The same input always produces the same hash, but you cannot reverse a hash back to the original input.
Common uses: password storage, file integrity checks, digital signatures, and data deduplication.
Security note: MD5 and SHA-1 are considered weak for security purposes. Use SHA-256 or SHA-512 for cryptographic applications.
