Immutable data

An application on the exorbin.com website can convert any block of data into a near unique 64 character string of characters. Fun with SHA256 So “abc” converts to ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad My name, “Richard Coyne”, converts to ba7c5c9e90f05540084e798effd0389b60ec98677662017065d34a0b880778a7 Here’s some Shakespeare “To be, or not to be — that is the question: Whether ’tis nobler in the mind to … Continue reading
