Re: Regarding Decryption of AES128 encrypted data in RPGLE and query regarding CRC 32

RTFM.  IBM i Db2 for i SQl reference.

Chapter 4 Build-in functions

Scalar functions

Encript...  Various algorithms.

In RPG use:  EXEC SQL set :encripted = Encript(:data, :key, :hint);

Recovery . . . : Do one or more of the following and try the request
again:
-- Verify the SQL statement in the area of the token ,1. Correct the

statement. The error could be a missing comma or quotation mark, it
could
be a misspelled word, or it could be related to the order of clauses.

-- If the error token is <END-OF-STATEMENT>, correct the SQL statement

because it does not end with a valid clause.

Let me find you a more applicable link:
https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_74/db2/rbafzscale.htm
Look up the various encrypt/decrypt functions there.

First of all, you are trying to use a SQL function, NOT a RPG function.
So you have to use "imbedded sql".
If you know nothing about imbedded SQL in RPG you are probably better off
asking on the RPG list. They should be able to give you a couple of RTFM
links.

There is probably a way to do the encrypt/decrypt outside of RPG. One
method which comes to mind is to build an index or view over the file which
does the encrypting/decrypting for you before returning it to RPG.

I äm trying to use it as it's advised on below link but so far have been
unable to encrypt key in below program due to error mentioned previously.

Thanks.
