Method Detail

getY

public java.math.BigInteger getY()

Specified by:

getY in interface javax.crypto.interfaces.DHPublicKey

getFormat

public java.lang.String getFormat()

Description copied from class: LunaKey

Returns the name of the format used to encode the LunaKey object.

This will be one of

• proprietary: keys with sensitive information, where the LunaKey only contains a reference to the handle of the key; the actual key bytes can't be extracted for encoding
• X.509: public keys
• RAW: secret keys, if they're set to be extractable

Specified by:

getFormat in interface java.security.Key

Overrides:

getFormat in class LunaKey

Returns:

the format of the encoded key

getEncodedInternal

protected byte[] getEncodedInternal()

Overrides:

getEncodedInternal in class LunaKey

verifyClassAndType

protected void verifyClassAndType()

Checks that the existing object handle being wrapped is a public DH key.

Overrides:

verifyClassAndType in class LunaKey

Throws:

LunaException - if there is a mismatch
