Iam trying to figure it out what kind of encryption is use on this code:

<tr>
<td bgcolor="ffffff"><b>Phone:</b><br>^8\g/+Etnu</td>
<td bgcolor="ffffff"><b>Email Address:</b><br>:<'mtHU\{]C9P#F|kG7Sz </td>
</tr>

In the case that I have the valid phone and email address..... is it posible to find the KEY wich encrypt/decrypt that code?
