[FIX] Connect using trusted client certificate

 - At present if trusted client certificate having key
   encrypted with sha2-4096 is passed the response
   received is BadCertificateUseNotAllowed
 - According to CTT (Test case 052.js in Security
   Certificate Validation) the expected result is Good
 - Fixed the same by changing the max key length value
