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

Can we directly use decryption function without doing encryption
programmatic way as we already have encoded values we just need to decode
it i tried the same but getting below error :-

1 **free
2 dcl-s enc varchar(130);
3 dcl-s psw char(31) ccsid(37)
4 inz('6-9d15-ec98bcc81ec4275OIM1TS7LI');
5 dcl-s text char(88) ccsid(37);
6 text = 'u3VtNgfyWU9faZc3Iaa8ZWbE5UZCfmC17yA4MyW0ghflt9dNQNDp+
7 CcgMZiG/kXPE4vv2CHL93B4iKiODHxxdVA==';
8 // exec SQL Set :enc = encrypt_AES(:text, :psw);
9 // DSPLY SQLCODE;
10
11 exec SQL Set :enc = decrypt_char(:text,:psw);
12 DSPLY SQLCODE;
13 eval *inlr=*on;

*SQLCODE = -171*

In addition, note that the field in question is defined with keyword
CCSID(37), so system value should not matter.

Rob,

The system that I performed that test on, that is back-level on PTFs at

V7R3, has QCCSID=37.

I also performed the identical test on another V7R3 system that is "up

to date" on PTFs, and it ran just fine.

Mark,

I think we've determined it's not the PTF's. It's the value of

DSPSYSVAL QCCSID.

Encryption hates 65535.
