ProtectedProductSerialNumber class>>instanceEncodingKey missing

Hi,

This class has seen some changes in version 6 which causes subclasses
now to require the #instanceEncodingKey class method. The encoded
scribble example uses the MyCompanySerialNumber class which doesn't have
this method and therefore doesn't work anymore.

Am I right in thinking that the instance method #encodingKey just needs
to be moved to the class side? (it seems to work)

Thanks,

Ted

Well, actually it doesn't work ...

On further investigation, I copied the methods from
AnotherCompanySerialNumber and managed to get it to work, however the
unlock key was about a mile long so I tried to change the coding from
Elgamal back to PC1 by changing the serialNumberProtectorClass. Of
course this required different #instanceEncodingKey/#instanceDecodingKey.
In D5 the encoding was generated from
        (PC1Cipher withStrength: 56) key
but this failed as PC1SerialNumberProtector>>encrypt: requires an
integer instead of a byte array. So I changed the instance encoding into
        LargeInteger fromBytes: (PC1Cipher withStrength: 56) key.
This did generate a key, but then the decoding failed:

testValidLicence
        | key no |
        key := MyCompanySerialNumber new.
        no := key productId.
        self assert: (MyCompanySerialNumber fromString: (key displayString))
productId = no.

So I guess I'm still misusing something but I'm really stuck now.

Can anybody shed some light on this?

Thanks,

Ted
