You could use beforeRender to modify links on the list I guess, the same, just in reverse, when url is received.

Thanks Klas

but it may be not as easy when on the other side you have live values that retrieve values from the URL. If they are encrypted the live value plugins won't decode

Hi

For receiving encrypted url variables (e.g. email addresses ) I am using SEBLOD standard URL variable live value plugin which does decode Base64 encrypted variables.

Hi Michal

thanks for the info !

Do you confirm the URL variable live plugin understands a encrypted variable with the base64_encode() function ?

thanks

cyril

Yes I am using it often, you have to enable base64 encryption in the live plugin config. 

Michal

thanks a lot

Just be warned that base64 is not an encryption, it is just another format for text that can be read by anyone. To get string encrytped and decrypted you wold need to run it trough some real encoding / decoding script, Joomla has built-in Crypt class to do that.
