Method Detail

initialize

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

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

 PssKeyPairGenerator keyGen = (PssKeyPairGenerator)KeyPairGenerator.getInstance("RSASSA-PSS", "IAIK");
 keyGen.initialize(strength, pssParamSpec);
 ...
 

Parameters:

strength - the length of the key in bits.

params - the PSS parameters to be set for the RSASSA-PSS keys

Throws:

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

initialize

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

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

 PssKeyPairGenerator keyGen = (PssKeyPairGenerator)KeyPairGenerator.getInstance("RSASSA-PSS", "IAIK");
 keyGen.initialize(strength, pssParamSpec, secureRandom);
 ...
 

Parameters:

strength - the length of the key in bits.

params - the PSS parameters to be set for the RSASSA-PSS keys

secureRandom - the random number generator

Throws:

java.security.InvalidParameterException - if the supplied parameters do not represent PSS 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 PSS parameters. When using this initialization method, an explicit cast to PssKeyPairGenerator is required:

 PssKeyPairGenerator keyGen = (PssKeyPairGenerator)KeyPairGenerator.getInstance("RSASSA-PSS", "IAIK");
 keyGen.initialize(strength, publicExponent, pssParamSpec, secureRandom);
 ...
 

Parameters:

strength - keyLength the length of the key in bits.

publicExponent - the public exponent

params - the PSS parameters to be set for the RSASSA-PSS keys

secureRandom - the random seed

Throws:

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

initialize

void initialize(java.security.spec.AlgorithmParameterSpec params)
                throws java.security.InvalidAlgorithmParameterException

Initializes this PssKeyPairGenerator with the given RSAPssParameterSpec.

Parameters:

params - the RSAPssParameterSpec for initializing this generator

initialize

void initialize(java.security.spec.AlgorithmParameterSpec params,
              java.security.SecureRandom random)
                throws java.security.InvalidAlgorithmParameterException

Initializes this RSAPssKeyPairGenerator with given RSAPssParameterSpec and random number generator.

Parameters:
