Best cipher for c# and PHP? -

I have applied a C # that interacts with my website via PHP (via encryption) and Visa.

I was wondering which best cipher is to use and if there is a cipher when encrypting / decrypting on different scripts.

I also have to think that data in a different format before encrypting me.

e.g. Say I am encrypting with PHP, I have to convert the data into ASCII before encrypting it. Just to make sure that I do not get stuck in the format for ages;)

thanks

There is no" best "cipher, but I recommend using an encryption algorithm which has been used by many like Triple DES or AES.

The contents of the target string should not be affected by the type of encryption they work at the encoding level at the byte level.
