Generating the Private Key -- Windows

In Windows:

1. Open the Command Prompt (Start > Programs > Accessories > Command Prompt).

C:Program FilesListManagertclwebbincerts

3. Type the following:

openssl genrsa -out rsa.private 1024

4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.

NOTE The number '1024' in the above command indicates the size of the private key. You can choose one of five sizes: 512, 758, 1024, 1536 or 2048 (these numbers represent bits). The larger sizes offer greater security, but this is offset by a penalty in CPU performance. We recommend the best practice size of 1024.
