Hi all,

I just joined a new development company and currently DES has been used for data encryption. I am trying to gather some details about upgrading to either Triple DES or AES. I did have a look at few documents on comparing those, but if any of you experts have any suggestion onto which is better Triple DES or AES, I will really appreciate any kind of information.

Thank you!

AES definitively and especially with 256bit or more key.

Thanks, Michael. Is there any specific advantage for using AES?? I think AES is only for 10g and 11i(DBMS Crypto package). But we have 9i databases as well. I think I will have to use Triple DES(opfuscation kit) for 9i databases and AES for 10g databases.
Is that advisable?

Thanks much!

Created about 10 years after the previous DES. Isn't it a good reason in security matter?

If you work in 9i, you have to use 3DES unless you load some Java AES classes in Oracle JVM.

Thanks, Michael. We have more 9i databases than 10g, so I guess we will go with Triple DES for now..

Any clue of what the script change will be for DES to Triple DES??

Thank you!

I don't know, use DES3 instead of DES, use long enough key, in brief follow what is in the documentation.
