Well, it seems to work for my small test.
I needed to add #unsignedLongAt: index bigEndian: aBool  to ByteArray to my
compatibility layer.
Then I modified #decryptString: aString with: aKey   and  #decryptToString:
someData with: aKey
to do a

^ decryptedData asByteArray asString.

instead of

^String fromByteArray:  decryptedData asByteArray .

Because GemStone String does not implement  #fromByteArray:  and to avoid
another extension method...

Paul, shall I commit this change to the Pharo version since in Pharo
#fromByteArray: ends up doing the same?

Thanks,
