Hello,

I wanted to use a simple encryption technique, So found a base64 encryption technique and i am using it.

I just need some suggestions from you guys, If is preferable / Good to use this kind of encryption , If not which is the best technique to use.

Base64 is no an encryption mechanism - it is an data conversion mechanism. It requires no key and is completely insecure. If anyone reading your data has any idea of data communications, it is immediately readable.

Instead, look at using Session information, which is stored in cookies. You can use proper encryption on the content if you need to.

Agree, Hardly one line of code and original string is with you to break Base64(which is indeed not an encryption technique). Sessions will be more secure. 5ed.

It is not encryption. Not at all. As such — it's good to use.

Forget security — using base64 is exactly the same as writing in open text. The major purpose of this encoding: encoding of binary files/streams using only ASCII characters. This is one of MIME types. See http://en.wikipedia.org/wiki/Base64[^].

What to advise to use instead? I don't know — it depends on what do you want to do. You just need to get some basis education in this field.

Start from here: http://msdn.microsoft.com/en-us/library/fkytk30f.aspx[^].

Consider the Sol1, Sol2
base64 is a Encoding Technique to send the data over HTTP protocols. It's good to use.

if you want to really encrypt the data, go for DES encryption which you can find in
