Hi, I may open my mouth too early as I am not very knowledgeable in the area, but isn't there a time stamp with every signature (meaning the time when it was encrypted) ? If so, that would : 1/ change the data 2/ hence change the encryption and compression you can get out of it (you're using gzip -9) Best regards, Alain.
