I am calling webservice in my Apex class. I don't want to store the information in Salesforce. I am showing the information in VF page using wrapper class. But now i need to display few of the fields in encrypted format. Is it possible ?

  • Do you mean you want to display them as if they had been stored as encrypted custom fields, or just that you want to display them in "an encrypted format" ? Commented Jun 13, 2014 at 9:02

If you have an Apex class providing information to a Visualforce page, and you wish to "encrypt" some of the fields before displaying them... could you use the Apex standard Crypto library?

You can read more on the Crypto class in the docs. Note that in order to display the encrypted value of the string on the page I had to run it through the Base64 encoding class too.

So as an example, if you had a super simple controller like:

public class HashMeUp() {

    public string myHash = 'Hello World!';

    public string getMyHash() {

        return EncodingUtil.Base64Encode(Crypto.encryptWithManagedIV('AES256',
                                                                     Crypto.generateAesKey(256), 
                                                                     Blob.valueOf(String.valueOf(myHash))));
    }

and the accompanying Visualforce page

<apex:page controller="HashMeUp">

    <h1>{!myHash}</h1>

</apex:page>

You would not see "Hello World!" on your page, as you might expect from your variable instantiation, you would see this:

tgcwXMgmta06XPyYQWmSKU/NUmj8RIdHxpSWTXhCaG0=

The encoded version of the string..

See:

encrypted

Is that sort of what you are after??
