WebDescription It is essential that keys in symmetric-key algorithms are random bytes, instead of passwords or other predictable data. The random bytes should be generated using a cryptographically-secure pseudorandom number generator (CSPRNG). WebSep 20, 2024 · It's used in cryptography to flip bits of a message in a certain way such that the recipient can flip the same bits through knowledge of a secret key to recover the message, although anyone intercepting the message shouldn't be able to recover the original message without knowledge of this key.
