Providers supply a SecureRandom implementation). Other uses the SecureRandom implementation One also has a SecureRandom argument, while the Methods that have an AlgorithmParameterSpecĪrgument. Provider what to do about the algorithm-specific parameters (if any) to beįor situations where a set of algorithm-specific parameters already Since no other parameters are specified when you call the aboveĪlgorithm-independent init methods, it is up to the ![]() Providers supply a SecureRandom implementation), and one that takes just a (or a system-provided source of randomness if none of the installed Of the highest-priority installed provider as the source of randomness Keysize argument, and uses the SecureRandom implementation Method in this KeyGenerator class that takes these two universally The only difference between the two is the initialization of the object:Īll key generators share the concepts of a keysize and a Manner, and in an algorithm-specific manner. There are two ways to generate a key: in an algorithm-independent Generated, the same KeyGenerator object can be re-used to generate further ![]() KeyGenerator objects are reusable, i.e., after a key has been Key generators are constructed using one of the getInstance This class provides the functionality of a secret (symmetric) key generator.
