Information such as TCT_LINK indicates the specific name of the AP_SSID.

Each line in the last formed encrypted string represents only one type of information, that is, one of the name, access password, or encryption method of the wireless network. In this way, the wireless network access information can be transmitted in the form of an encrypted character string. For example, the name and access password of the wireless network are represented by the following encrypted string:

AP_SSID: TCT_LINK

AP_PSWD: 123456

At the same time, in order to identify the beginning and end of the contents of the encrypted string, a specific start identifier is used to indicate the start, such as AP_BEGIN, and then the end is indicated by a specific end identifier, such as AP_END. Thus, when generating an encrypted string, the start identifier is entered at the beginning of the encrypted string, and the end marker is entered at the last line. Finally, the encrypted string of the name, access password and encryption method of the wireless network is generated as follows:

AP_BEGIN

AP_SSID: TCT_LINK

AP_PSWD: 123456

AP_TYPE: WPA-PSK

AP_END
