Hi,
I'm trying to encrypt credit_card numbers in MySQL 3.23.33. I want to
decrypt them when I retrieve them.
I've tried:
mysql> insert into payment (payname1,ccaccount) values
("Kinney",encode('5555444433332222','Ilwfci');
ERROR 1064: You have an error in your SQL syntax near '' at line 1
mysql> insert into payment (payname1,ccaccount) values
("Kinney",encode(5555444433332222,Ilwfci);
ERROR 1064: You have an error in your SQL syntax near 'Ilwfci)' at line 1
mysql> insert into payment (payname1,ccaccount) values
("Kinney",ENCODE('5555444433332222',Ilwfci);
ERROR 1064: You have an error in your SQL syntax near 'Ilwfci)' at line 1
mysql> insert into payment (payname1,ccaccount) values
("Kinney",encode(5555444433332222,'Ilwfci');
ERROR 1064: You have an error in your SQL syntax near '' at line 1
I have "ccaccount" set up as a blob.
As you can see, all I get is error messages. What am I doing wrong?
After I get them in, my next question is how to get them back out.
According to the manual, one should use: DECODE(crypt_str,pass_str) where
"crypt_str" should be a string returned from ENCODE(). This seems to be a
catch-22, though. Wouldn't I have to know the value of "crypt_str", i.e.
the credit_card number in order to get that encrypted string out of
ENCODE()?
Thanks.
