This conversion process has two characteristics: the encryption process is irreversible, meaning that we cannot infer what the original plaintext is by analyzing the output hash value; the input plaintext and the output hash value are one-to-one corresponding, meaning that any change in the input information will inevitably lead to a change in the final output hash value.\n\nIn the blockchain,"}]}],"pr":"7803f44306e04c92d1be17c172bfedaa194060caab47090df45658818273e21e"}
