For my tests I used the blob field (not varchar or anything else), but
compared to your tests, I didn't use MySQL 5.0.6 (as it's still a beta)
but
I used MySQL 4.1. Maybe that's part of the problem, although I'm not sure.
FWIW: I tested it on 4.0.23-standard, with the same

Table: a
Create Table: CREATE TABLE `a` (
`a` blob
) ENGINE=MyISAM DEFAULT CHARSET=cp1251
COLLATE=cp1251_bin
I think of using AES Encryption for some time now, because
solved it by limiting the number
of characters by 256 in my application, but ofcourse that's not ideal...
Thanks,
Martin

Hi,
I think of using AES Encryption for some time now, because it seems to be
the most secure encryption method in MySQL at this moment and table
encryption of some sort is not possible. In the documentation I read BLOB
fields are recommended for storage of data with AES_Encrypt, otherwise you

I really wish MySQL would support table wide encryption because more
info is
being encrypted. And even with that said, laws are only good for those who
abide by them. :-)

What i think Aes encryption reduce the risk but does not make data 100%

Nobody gives you a 100% garanty.

Nevertheless you should be aware that the information is travelling
unencrypted between the mysql client and server unless you're using SSL
tunneling or similar techniques.
Sorry, since mysql 4.0, SSL is of course possible.

Hi Herb,
You should be able to specify 255 as the PRI KEY length... I think.
CREATE TABLE table (
col TINYBLOB NOT NULL,
PRIMARY KEY (col(255))
);
Hope that helps.

TINYBLOB does seem to hold the value properly.
I can't use a TINYBLOB in a primary key. Is this not allowed?
The ALTER statement complains that I am using a column without a length

Specify a length, then. :-)
