Cheking public or private key

[Patrice Guérin <guerinp@xxxxxxxxx>]

Dear All,

Is there a way to check if a EVP_PKEY is a public or private key ?

In the case of use of EVP_Sign or EVP_DigestSign functions, an 
application leads to crash with SIGSEGV
if an incorrect key is given when finalizing process.

Thanks in advance for your answers.

Kind regards,
Patrice.
