Reverse encryption algorithm used in POST form

I have client native app (vc++), it is packed by themida. Each time this app client send POST form data to server, data is encrypted with random key. Here is 1 example

plain_text: hello

data after encrypted something like:

encrypted_text = 6NTkCAvY7NqYFz5lU1JjNQ==

EncKey = ZCj35hEvmxMOQPrzYzov8CsOpKJayFoRUoc98FGTnnkUi+YZW5pzNHXhCuvKKqq4RAATdn1qSsZ558i2cS2ClfvXvfb3OQEgBj9+GcdMMBasdKGYu88hxFfELkqWKxyZijY+UCVvE8KLv0+65nMzbvQ12OJGRhE1JJd1FCtW+qU=

(EncKey is random and always 172 characters).

I want to have algorithm to gen EncKey and algorythm to encrypt/decrypt data

code should be .NET or PHP
