Hi, I have been testing with a Siemens CX65 and have been successfully able to send settings to a GSM modem from the siemens website. The reason for this is I need the binary. However, the PIN assigned is random as per the website. I want the PIN to default to a value such as 0000, so that when the settings are sent to a user's phone, the PIN is easy to remember. Please tell me how I can parse the binary to extract the PIN and reset it. This probably requires HMAC reverse calculation, and I am not sure how to go about it. Help will be much appreciated. Thanks. | |||

Not sure about about other issues , however you cannot get your PIN from the HMAC as It is not possible to compute a key from the hash value. In short hash alogorithms work 'one way' . This is a security feature. | |||
