I know the Zclasses do this automatically, what's the majick > trick for this in python? The Find machinery (and therefore, ZCatalog) uses the method "objectItems" to locate the children of an object. If such a method does not exist or does not return the sequence of children, the catalog will not find them. Dieter

Secure storage of credit card info
by R. David Murray 13 Jun '00

13 Jun '00

OK, any of you out there who have thought about ecommerce, cryptography, and zope, I've got a design question for you. Actually, this question is independent of zope, but I need to solve it in a zope context. You have a ZCommerce site. You accept credit cards, and securely communicate with a CC processor to verify the transacton. Now, you want to save the CC# and other info in case something needs to be done with it later, and probably store the CC# so this customer doesn't have to type it in again later. Regardless of whether you are storing this info in a relational database or in the ZODB, how do you secure that information? Ideally I'd like it to be encrypted on disk. Now, storing it in a database probably makes it pretty hard to grep out even if a hacker manages to snarf the database file, but I'd like to encrypt it. But if I encrypt it, I have to have a decryption key somewhere. Where do I store the decryption key so that the cracker who snarfs the database file can't get it (just in memory somewhere?), and yet have the system be able to boot itself, including having the key, without human intervention? It seems to me like this is a Hard Problem, but I'm not up on the current cyrptography practice. So if there is a well known general solution, I'd love to hear about it. Otherwise, does anyone know what current Best Practice is? --RDM

Not to be picky, Ken, but since you are from Digicool... could you take a look at your own message at: http://www.egroups.com/message/zope/33350?&start=33322 (I checked both IE and Netscape, from PC.) Lately there have been quite a few mangled messages at egroups. Could you find out what went wrong and let people know how to prevent this kind of mangling? I have heard people saying repeatedly that please do not use HTML-format e-mail messages, did you use HTML format? Or is it related to a particular mail software that you use? regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

del dict[kw] in DTML

I can't find a way to emulate the pythonesque "del dict[kw]" within DTML without rebuilding the dictionary from scratch. May I? -- "This company has performed an illegal operation and will be shut down. If the problem persists, contact your vendor or appeal to a higher court." - Signal11 on slashdot

mail host question
by Sean Kelley 13 Jun '00

13 Jun '00

I am having some problem configuring zope mail to work properly, particularly with PTK v 0.7.1. When I logon as a new member, its says "successful", but I get no mail to confirm my logon (I did get it to work once but don't know how). I have the smtp host set to an IP address for an smtp mail server. I tried a couple of others by name such as "mail.domain.com" but got an error relating to needed/missing "domain" The permissions on the various zope security screens has all possible users set to "use mail host" Sean Kelley Prompt Software, Inc. www.promptsoftware.com sean(a)promptsoftware.com voice: (415) 382-8840 fax: (415) 382-8868

Ack - apparently something in the win installer thinks that empty files are not worth preserving :( Note that I've tweaked this and re-uploaded the win32 beta. If you've already downloaded it, the above solution is fine (just create an empty file named __init__.py in your ZServer/medusa directory).
