what kind of encryption DB2 is offering

I think the question is how many type of encryption DB2 offering? that link seems saying how to install it.

"how many types" -- I don't know what you're asking there.

I mean how many diff type of encryption for DB2 , .e.g TDE, SSL and ... ?

TDE and SSL are different products that work well together, but aren't really different types of encryption.  SSL is an encryption technique (the math and routines for encryption/decryption).  TDE is an encryption management and would use something like SSL to do the actual encryption.  

I haven't heard the term TDE used with DB2, but DB2's encryption/decryption is transparent to the user.  If you can use some bullet points about about DB2's encryption tools, this might help:

"TDE and SSL are different products that work well together, but aren't really different types of encryption.  "

yes. SSL more on network side and TDE more on physical file side.

also, will Column level encryption -create high performance impact ?

hi Tomas,

"DB2 offers encryption over the network"

Does this kind of encryption has any thing related to the DML inside ? it decrypt data at both client and server end ?

is it SSL network encryption ?

Hi,

Yes, I was talking about SSL network encryption and no it has nothing to do with DML.
SSL makes sure that data transfer between client/server is encrypted regardless of other encryption methods used.
Data encryption can be done via UDF or SP and data is encrypted/decrypted at it's execution time.

"Data encryption can be done via UDF or SP"

user defined function and Store procedure inside DB2 ?

tks both
