Method Detail

initialize

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

JCA adapter for FlexiAPI method initialize(AlgorithmParameterSpec, SecureRandom): initialize the key pair generator using the specified parameter set and source of randomness.

Overrides:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

params - the parameter set used to generate the keys

javaRand - the source of randomness for this generator

Throws:

java.security.InvalidAlgorithmParameterException - if the given parameters are inappropriate for this key pair generator.

initialize

public final void initialize(int keysize,
                             java.security.SecureRandom javaRand)
                      throws InvalidParameterException

Initialize the key pair generator for a certain key size using a default parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness. (If none of the installed providers supply an implementation of SecureRandom, a system-provided source of randomness is used.)

Overrides:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

keysize - the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

javaRand - the source of randomness for this generator

Throws:

InvalidParameterException - if the keysize is not supported by this KeyPairGenerator object.

generateKeyPair

public final java.security.KeyPair generateKeyPair()

JCA adapter to FlexiAPI method genKeyPair(): generate a key pair. Unless an initialization method is called using a KeyPairGenerator interface, algorithm-specific defaults will be used. This will generate a new key pair every time it is called.

Overrides:

generateKeyPair in class java.security.KeyPairGeneratorSpi

Returns:

a newly generated KeyPair

initialize

public abstract void initialize(AlgorithmParameterSpec params,
                                SecureRandom random)
                         throws InvalidAlgorithmParameterException

Initialize the key pair generator using the specified parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness. (If none of the installed providers supply an implementation of SecureRandom, a system-provided source of randomness is used.).

Parameters:

params - the parameter set used to generate the keys

random - a source of randomness

Throws:

InvalidAlgorithmParameterException - if the given parameters are inappropriate for this key pair generator.

initialize

public abstract void initialize(int keysize,
                                SecureRandom random)
                         throws InvalidParameterException

Initialize the key pair generator for a certain keysize using a default parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness. (If none of the installed providers supply an implementation of SecureRandom, a system-provided source of randomness is used.)

Parameters:

keysize - the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.

random - the source of randomness for this generator

Throws:

InvalidParameterException - if the keysize is not supported by this KeyPairGenerator object.

genKeyPair

public abstract KeyPair genKeyPair()

Generate a key pair. Unless an initialization method is called using a KeyPairGenerator interface, algorithm-specific defaults will be used. This will generate a new key pair every time it is called.

Returns:

a newly generated KeyPair
