I want to secure the text by using the MySQL encode function:
Encode($longtext, $mykey), however I am not able to retrieve the text using:
Decode($longtext, $mykey), and when I do this, I only retrieve some weird characters.
My Questions are:
1. Why I retrieve some weird text when using Decode()?
2. Besides Encode, what other function can be used to BOTH Encrypt and Decrypt the text?
Thank you

Answers
which one is the most secure?
To tell you the truth, i have limited knowledge on which one is most secure and cannot help you there.
can mcrypt encrypt and decrypt a large text?
http://us3.php.net/manual/
This webpage has whole lot of information on this part if you are interested.
From link above:
AES_ENCRYPT() and AES_DECRYPT() were added in MySQL 4.0.2, and can be considered the most cryptographically secure encryption functions currently available in MySQL.
Keep in mind that using a MySQL function to encrypt the data means the data is sent in cleartext from your application to the SQL server then encrypted right before it is stored. When unencrypted, it is again sent in clear text to your application. If they are on the same machine this shouldn't be a problem but if the data is coming from a client workstation, it will be sent in cleartext from the client to the webserver then to the sql server, then encrypted. Even if you use the PHP function, it will be sent in cleartext from the client to the webserver.
It really depends on the design of your app and where the data is comming from and where it needs to be encrypted. You could need a combination of SSL, mcrypt and/or aes_enctypt.

1. Why I retrieve some weird text when using Decode()?
The reason you can get weird character may be that you are storing them as long text. Store the encoded values as 'BLOB' column instead.
2. Besides Encode, what other function can be used to BOTH Encrypt and Decrypt the text?
