Constant Field Values

NHASH

public static final int NHASH

The registration contains 112 bits of hash (14 bytes). NB. (NSALT + NHASH) must be divisible by 5.

LICENSEVERSION

public static final java.lang.String LICENSEVERSION

The version for licensing purposes. Change this to require users to get new licenses.

Constant Field Values

ownerPerson

public java.lang.String ownerPerson

The person this is registered to. For a shrink-wrapped (boxed) copy, this will be the empty string.

ownerOrg

public java.lang.String ownerOrg

The organisation this is registered to. For a shrink-wrapped (boxed) copy, this will be the empty string.

licenseKey

public java.lang.String licenseKey

The license key.

Constructor Detail

CpcLicence

public CpcLicence()

Method Detail

isValid

public boolean isValid()

Whether the registration key is valid.

check

public void check()

Check that the registration key is valid.

Throws:

java.lang.IllegalArgumentException - If the registration key is no good.

generateMAC

protected byte[] generateMAC(byte[] salt)

Generate the hash value.

Parameters:

salt - The first NSALT bytes of this are used as salt.

Returns:

The hash value. Only the first NHASH bytes of this are used.

cpmarshal

protected void cpmarshal(java.io.DataOutputStream dest)
                  throws java.io.IOException

Description copied from class: ccs.cdb.CDBObject

override this to marshal your data, just like marshal. The data will be in the object's fields when this is called (rather than within any UI objects).

Specified by:

cpmarshal in class ccs.cdb.CDBObject

Parameters:

dest - The stream to marshal onto.

Throws:

java.io.IOException - If this breaks (breaks the CDB too).

cpunmarshal

protected void cpunmarshal(java.io.DataInputStream src,
                           int marshalver)
                    throws java.io.IOException

Description copied from class: ccs.cdb.CDBObject

override this to unmarshal your data, just like unmarshal.

Specified by:

cpunmarshal in class ccs.cdb.CDBObject

Parameters:

src - The stream to unmarshal from

marshalver - The marshal version of the data in src - i.e. the version of this class which wrote the data. This may be different from the current marshalVersion. If so (i.e. the stored data is the wrong version) your method should allow for it. This allows comparatively painless data migration between versions of your objects.

Throws:

java.io.IOException - if this breaks (breaks the CDB too).
