The message digest algorithm used to calculate the digest of the encoding parameter.

mgf

protected long mgf

The mask to apply to the encoded block.

Constructor Detail

RSAPkcsParams

protected RSAPkcsParams(Mechanism hashAlg,
                        long mgf)

Create a new RSAPkcsarameters object with the given attributes.

Parameters:

hashAlg - The message digest algorithm used to calculate the digest of the encoding parameter.

mgf - The mask to apply to the encoded block. One of the constants defined in the MessageGenerationFunctionType interface.

Method Detail

getHashAlgorithm

public Mechanism getHashAlgorithm()

Get the message digest algorithm used to calculate the digest of the encoding parameter.

Returns:

The message digest algorithm used to calculate the digest of the encoding parameter.

getMaskGenerationFunction

public long getMaskGenerationFunction()

Get the mask to apply to the encoded block.

Returns:

The mask to apply to the encoded block.

setHashAlgorithm

public void setHashAlgorithm(Mechanism hashAlg)

Set the message digest algorithm used to calculate the digest of the encoding parameter.

Parameters:

hashAlgorithm - The message digest algorithm used to calculate the digest of the encoding parameter.

setMaskGenerationFunction

public void setMaskGenerationFunction(long mgf)

Set the mask function to apply to the encoded block. One of the constants defined in the MessageGenerationFunctionType interface.

Parameters:

mgf - The mask to apply to the encoded block.

toString

public String toString()

Returns the string representation of this object. Do not parse data from this string, it is for debugging only.

Overrides:

toString in class Object

Returns:

A string representation of this object.

equals

public boolean equals(Object otherObject)

Compares all member variables of this object with the other object. Returns only true, if all are equal in both objects.

Overrides:

equals in class Object

Parameters:

otherObject - The other object to compare to.

Returns:

True, if other is an instance of this class and all member variables of both objects are equal. False, otherwise.

hashCode

public int hashCode()

The overriding of this method should ensure that the objects of this class work correctly in a hashtable.

Overrides:

hashCode in class Object

Returns:

The hash code of this object.
