Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server

Using Encryption

The EncryptKey parameter or the profile Encrypt Key parameter and the encryption key used in the cfgfmt tool command syntax must match.

The cfgfmt.exe syntax affects how the EncryptKey parameter is used, as shown in the following examples. In these examples, input_text is the ldxxxxxxxxxxxx.txt or the gkxxxxxxxxxxxx.txt file that you will convert to a binary profile, output_binary is the binary ldxxxxxxxxxxxx or gkxxxxxxxxxxxx file, and Secret is the encryption key.

Syntax examples

cfgfmt input-text-file output-binary-file

If input-text-file sets the EncryptKey parameter to 0, then output-binary-file is not encrypted. If input-text-file sets EncryptKey to a non-zero value, then output-binary-file is encrypted with that value.

cfgfmt -eSecret input-text-file output-binary-file

If the EncryptKey parameter has the value of 0 or is not included in input-text-file, the Secret is used to encrypt the output-binary-file. If input-text-file sets the EncryptKey parameter to a nonzero value and the -e option is used, then output-binary-file is encrypted with the EncryptKey parameter set in input-text-file and Secret is ignored.

cfgfmt -E input-text-file output-binary-file

The -E (uppercase) option means that any value specified for the EncryptKey parameter in input-text-file is ignored. However, because Secret is not specified in this example, output-binary-file is not encrypted. Nevertheless, the EncryptKey parameter and its value, if specified in input-file-text, will be included in output-binary-file for possible encryption at a later time.

cfgfmt -E -eSecret input-text-file output-binary-file

The -E (uppercase) option means that any value specified for the EncryptKey parameter in input-text-file is ignored and the output-binary-file is encrypted with the Secret key. However, the EncryptKey parameter and its value, if specified in input-text-file, will be included in output-binary-file.
