Method Detail

getInstance

public static MyRSAPublicKey getInstance(byte[] encoded)

getSignatureAlgorithm

public ISignatureVerificationAlgorithm getSignatureAlgorithm()

Gets the signature algorithm object that is held and initialised by this key. It is ready to verify messages and must not be reinitialised.

Specified by:

getSignatureAlgorithm in interface IMyPublicKey

Returns:

the signature algorithm object that is held and initialised by this key

getModulus

public java.math.BigInteger getModulus()

getPublicExponent

public java.math.BigInteger getPublicExponent()

getAlgorithm

public java.lang.String getAlgorithm()

Specified by:

getAlgorithm in interface java.security.Key

getFormat

public java.lang.String getFormat()

Specified by:

getFormat in interface java.security.Key

getKeyLength

public int getKeyLength()

Description copied from interface: IMyPublicKey

Returns the length of the key. The length of the key often corresponds with the security it provides.

Specified by:

getKeyLength in interface IMyPublicKey

Returns:

the length of the key

getAsSubjectPublicKeyInfo

public mybouncycastle.org.bouncycastle.asn1.x509.SubjectPublicKeyInfo getAsSubjectPublicKeyInfo()

Description copied from interface: IMyPublicKey

Gets the key as a SubjectPublicKeyInfo object.

Specified by:

getAsSubjectPublicKeyInfo in interface IMyPublicKey

Returns:

the key as a SubjectPublicKeyInfo object

getParams

public mybouncycastle.org.bouncycastle.crypto.CipherParameters getParams()

toXmlElement

public org.w3c.dom.Element toXmlElement(org.w3c.dom.Document a_doc)

Builds an XML Node containing the public key data. This is compliant to the W3C XML Signature standard

Specified by:

toXmlElement in interface IXMLEncodable

Parameters:

a_doc - the root document

Returns:

an XML Node

equals

public boolean equals(java.lang.Object a_publicKey)

This method returns if two public keys have the same public key parameters.

Specified by:

equals in interface IMyPublicKey

Specified by:

equals in class AbstractPublicKey

Parameters:

a_publicKey - an other public key

Returns:

true if the keys have the same public key parameters; false otherwise

hashCode

public int hashCode()

Specified by:

hashCode in interface IMyPublicKey

Specified by:

hashCode in class AbstractPublicKey

Returns:

the public key`s hash code
