Method Detail

initialize

void initialize(int strength,
              java.security.spec.AlgorithmParameterSpec params)
                throws java.security.InvalidParameterException

Initializes the OaepKeyPairGenerator for generating keys with the given length and OAEP parameters. When using this initialization method, an explicit cast to OaepKeyPairGenerator is required:

 OaepKeyPairGenerator keyGen = (OaepKeyPairGenerator)KeyPairGenerator.getInstance("RSAES-OAEP", "IAIK");
 keyGen.initialize(strength, oaepParamSpec);
 ...
 

Parameters:

strength - the length of the key in bits.

params - the OAEP parameters to be set for the RSAES-OAEP keys

Throws:

java.security.InvalidParameterException - if the supplied parameters do not represent OAEP parameters

initialize

void initialize(int strength,
              java.security.spec.AlgorithmParameterSpec params,
              java.security.SecureRandom secureRandom)
                throws java.security.InvalidParameterException

Initializes the OaepKeyPairGenerator for a certain key length with the given random number generator and OAEP parameters. When using this initialization method, an explicit cast to OaepKeyPairGenerator is required:

 OaepKeyPairGenerator keyGen = (OaepKeyPairGenerator)KeyPairGenerator.getInstance("RSAES-OAEP", "IAIK");
 keyGen.initialize(strength, oaepParamSpec, secureRandom);
 ...
 

Parameters:

strength - the length of the key in bits.

params - the OAEP parameters to be set for the RSAES-OAEP keys

secureRandom - the random number generator

Throws:

java.security.InvalidParameterException - if the supplied parameters do not represent OAEP parameters

initialize

void initialize(int strength,
              java.math.BigInteger publicExponent,
              java.security.spec.AlgorithmParameterSpec params,
              java.security.SecureRandom secureRandom)
                throws java.security.InvalidParameterException

Initializes the key pair generator using the specified "strength" (desired key length in bits), public exponent, source of random bits, and OAEP parameters. When using this initialization method, an explicit cast to OaepKeyPairGenerator is required:

 OaepKeyPairGenerator keyGen = (OaepKeyPairGenerator)KeyPairGenerator.getInstance("RSAES-OAEP", "IAIK");
 keyGen.initialize(strength, publicExponent, oaepParamSpec, secureRandom);
 ...
 

Parameters:

strength - keyLength the length of the key in bits.

publicExponent - the public exponent

params - the OAEP parameters to be set for the RSAES-OAEP keys

secureRandom - the random seed

Throws:

java.security.InvalidParameterException - if the supplied parameters do not represent OAEP parameters
