WebKey Generation Create both asymmetric and symmetric cryptographic keys. MutableKey? Generates a new public-private key pair. Gets the public key associated with the given private key. Use attribute dictionary keys during cryptographic key generation. To prevent a key from being guessed, keys need to be generated randomly and contain sufficient entropy. The problem of how to safely generate random keys is difficult and has been addressed in many ways by various cryptographic systems. A key can directly be generated by using the output of a Random Bit Generator (RBG), a system that generates a sequence of unpredictable and unbiased bits. A RBG can be used to directly produce either a symmetric key or the random …
