I can see that both would be interesting for my application. Just as a thought, would the lzo algorithm be better than using zlib? It has a far smaller footprint than zlib and is _really_ fast. Cheers Angus ___ metakit mailing list - [EMAIL

Dont remember if I expressed my opinion already: * Compression: useful for large data, e.g. binary and string, less useful for other types. * Encryption: very useful. * Combination of the two: not sure where I'd use it. --JYL Andreas Muegge wrote: the implementation of encryption is

I am using compression already. Python properties combined with sting encode('zlib') handle it transparently to the user. Niki Spahiev ___ metakit mailing list - [EMAIL PROTECTED] http://www.equi4.com/mailman/listinfo/metakit

I suppose that this falls along the lines of I'll wait to see the implementation (TM). Since these are non-invasive changes to metakit, I'm always happy to see useful features. Here are my current comments with the proposed compression strategy: It seems that using the in-memory

Hi, the implementation of encryption is something I would like to see in Metakit. It would avoid another layer of complexity within the application using Metakit and thus the decision to use strong protection of data would be easier to made. I am not sure about compression. If we talk about

2003-10-10 Thread Jean-Claude Wippler
Two options not implemented in MK 2.4.9.2, are compression and encryption. Due to the column-wise design of MK, this may actually have substantial consequences. The idea, is that in a datafile with say layout names[first:S,last:S,phones[type:S,number:S]] it would be possible to designate

I would use encryption for storages that contain Tcl programs that represent my IP, definitely. I would use compression for compressable data, e.g. if I stored GIF or JPEG images as blobs. Not too sure about the combination, I can't think of a scenario where I'd like to use compressed +
