## Creating New Key Pairs

Note: If you name a new key file with the same name as some existing key file on your computer, you must use the password for the existing key file. New key files require a unique name.

- Select Tools -> Handle Key Pairs.

- The Key pairs window opens.

- Click New.
- Define the key pair details:

- Enter a name for the key pair.

- Click Make Keys.

- The Make Keys window opens.

- In the Make Keys window:

- In the User Information field, enter your user information.

- In the Destination information field, enter the file path and name for the private key and certificate files.

- The system warns you if there already exists a key or certificate file by that name.

- If you want to password protect your key and certificate, in the Destination information field, enter and confirm a password for the key and certificate.

- In the Parameters field, enter key length.

- Key length can be any number divisible by eight in range of 512 to 2048, for example 1600.

- Click Generate.

- The system returns to the Handle Key Pairs window.

- Click Save.

Note: Some phones do not accept themes that have been signed with theme creators' own certificates. This setting can be changed in the phone in the following way: select Tools -> App mgr -> Settings -> Software installation and choose the correct setting.
Note: It's not mandatory to create new key pairs every time a theme is packaged. Existing key pairs can be re-used for subsequent packaging.
