Interface RSAKeyPairGenerator
- BaseRSAKeyPairGenerator
public interface RSAKeyPairGenerator
An interface to an object capable of generating RSA key pairs. The
generator is first initialized, then used to generate one or more
key pairs.
Users wishing to indicate the public exponent, and to generate a key
pair suitable for use with the RSA algorithm typically
- Get a key pair generator for the RSA algorithm by calling the
KeyPairGenerator
getInstance
method with "RSA"
as its argument.
- Initialize the generator by casting the result to an
RSAKeyPairGenerator and calling the
initialize
method from this RSAKeyPairGenerator interface.
- Generate one or more key pairs by calling the
generateKeyPair
method from the KeyPairGenerator
class, as often as desired.
Note: it is not always necessary to do algorithm-specific
initialization for an RSA key pair generator. That is, it is not always
necessary to call the
initialize
method in this interface.
Algorithm-independent initialization using the
initialize
method in the KeyPairGenerator interface is all that is needed when you
accept defaults for algorithm-specific parameters.

public void initialize(int strength,
BigInteger publicExponent,
SecureRandom random)
throws InvalidParameterException
Initializes the key pair generator using the specified "strength"
(desired key length in bits), public exponent, and source of random
bits. Typical values for the public exponent are the Fermat primes
F4 and F0 (65537 and 3) and, less commonly, 17.
