Imagine a complex assembly line that processes your data:
Data is padded like fitting puzzle pieces into fixed 512-bit blocks
64 rounds of mathematical "mixing" operations
Websites store password fingerprints, not actual passwords
Powers cryptocurrency mining and verification
Verify document authenticity
Ensure downloads aren't tampered with
