ruby - how to encrypt text -


I need to encrypt a string (from the text field) which will later be decrypted when displayed.

I do not have to worry that it is quite safe, but not just to store data in plain text format.

How to do it easily on someone in the train?

If you are not concerned about security, then you can only base 64 Can change: 

  encoded = base64 :: encode (string) is decoded = base 64 :: decode (encoded)

anyway Binary data is also suitable for encoding.

This is not really encrypting because any developer can be estimated that its base is 64 encoded data.

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
