You receive the following error when creating your BlackBerry® Developer Certificate (.p12 file):
Usage error, ûgenkeypair is not a legal command
This happens when an “En Dash” character (Unicode U+2013) is used instead of the “Hyphen-Minus” (Unicode U+002D) in the command line when creating a BlackBerry Developer Certificate. The “Hyphen-Minus” is normally the character that appears when you press the “minus” key on your keyboard. However, some email clients and browsers can convert this character to “En Dash”.
Type out the command in the command prompt window instead of copying and pasting from a browser or email client.
