Q. Your RSA key is too small! or This CSR uses an unsupported key size.

A. For all certificates that we issue (including EV SSL), the RSA key size MUST BE at least 2048-bit as of 20-DEC-2010.
Note: To retain maximum compatibility across all browsers do not use an RSA key size of over 2048 at this time!
