I've been setting up a new MySQL/PHP site which will contain store
some CC details, and have been wondering how to pass the keys.
CC's are written in a similar way to:
INSERT INTO cc (ccName, ccNumber, ccDate)
VALUES (ENCRYPT('fred smith', 'mykey'),ENCRYP T('12345',
'mykey'),ENCRYP T('01.03', 'mykey'))
And they're read out using something along the lines of:
SELECT DECRYPT(ccName, 'mykey'), DECRYPT(ccNumbe r, 'mykey'),
DECRYPT(ccDate, 'mykey')
FROM cc
In order to reduce the chance of the key being noticed, either by a db
error exposing the SQL query (I know my PHP should do this in a
production system, but you never know...) I've tried issuing the
following commands, but I always get errors. Is there anyway of using
variables in the EN-/DECRYPT commands?
SET @enckey='mykey' ;
SELECT ENCODE('fred smith', @enckey); -- causes error
SELECT DECODE('fred smith', @enckey); -- causes error
Have I missed something either RTFM or just plain silly, or can I not
do this at all?
many thanks,

Hi,
I have generated two keys :
"C:>openssl req -nodes -new -x509 -keyout ben.key -out ben.crt -days
3650"
I try to encrypt/decrypt a string like "JOHN" with these asymetrics
keys. With the following code, it works.
I encrypt with the public key which is in the certificate.
I decrypt with the private key.
But why, the crypted message is different every time I start the
programm...?

Hi,
I had a look at the vast information on encryption in the MSDN and got
pretty confused. All I want to do is to encrypt a string into an encrypted
string and later decrypt that (encrypted) string again to a human readable
form. Can't be that difficult :).
Could you send me please into the right direction. Thanks in advance.

Hello,
I'm trying to encrypt passwords in my app. After discovering that
there's no simple function to do this, I wrote a wrapper class which
decodes a string using UTF8, encrypts it with TripleDES and returns a
Base64-encoded string. The decryption function does the reverse, i.e.
Base64-decodes the string, decrypts it with the same Key and IV, and
encodes it again with UTF8. The problem is that after decrypting, the
8th character is...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
