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

Dear Rishi,

do you read the answers you get?
I send you already yesterday the SQL Solution.
Here again the (embedded) SQL Source code (and don't forget to change your source attribute to SQLRPGLE)

DCL-S Text VarChar(20);
DCL-S Encrypted VarChar(256);
DCL-S Password VarChar(15) inz('yourPassWord')

Text = 'Whatever Text'
Exec SQL Set :Encrypted = Encrypt_AES(Text, PassWord);

Mit freundlichen Grüßen / Best regards

Birgitta Hauser

c/exec sql

C/END-EXEC

Message ID . . . . . . : SQL0104 Severity . . . . . . . : 30

Message type . . . . . : Diagnostic



Message . . . . : Token ,1 was not valid. Valid tokens: ) ,.

Cause . . . . . : A syntax error was detected at token ,1. Token ,1 is
not
a valid token. A partial list of valid tokens is ) ,. This list assumes

that the statement is correct up to the token. The error may be earlier in
the statement, but the syntax of the statement appears to be valid up to

this point.

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/rbafzscal
e.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.
