Constructor Detail

RSAPkcsOaepParameters

public RSAPkcsOaepParameters(Mechanism hashAlgorithm,
                             long maskGenerationFunction,
                             long source,
                             byte[] sourceData)

Create a new RSAPkcsOaepParameters object with the given attributes.

Parameters:

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

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

source - The source of the encoding parameter. One of the constants defined in the SourceType interface.

sourceData - The data used as the input for the encoding parameter source.

Preconditions:

(hashAlgorithm != null) and (maskGenerationFunction == MessageGenerationFunctionType.Sha1) and ((source == SourceType.Empty) or (source == SourceType.DataSpecified))

Method Detail

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class RSAPkcsParameters

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof RSAPkcsOaepParameters) and (result.equals(this))

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as an object of the CK_RSA_PKCS_OAEP_PARAMS class.

Returns:

This object as a CK_RSA_PKCS_OAEP_PARAMS object.

Postconditions:

(result != null)

getSource

public long getSource()

Get the source of the encoding parameter.

Returns:

The source of the encoding parameter.

getSourceData

public byte[] getSourceData()

Get the data used as the input for the encoding parameter source.

Returns:

The data used as the input for the encoding parameter source.

setSource

public void setSource(long source)

Set the source of the encoding parameter. One of the constants defined in the SourceType interface.

Parameters:

source - The source of the encoding parameter.

Preconditions:

((source == SourceType.Empty) or (source == SourceType.DataSpecified))

setSourceData

public void setSourceData(byte[] sourceData)

Set the data used as the input for the encoding parameter source.

Parameters:

sourceData - The data used as the input for the encoding parameter source.

toString

public java.lang.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 RSAPkcsParameters

Returns:

A string representation of this object.

equals

public boolean equals(java.lang.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 RSAPkcsParameters

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 RSAPkcsParameters

Returns:

The hash code of this object.
