Private Key Type and PEM Length

[Sudhir Voona]

Hi All,

I am sending my Query again ..

Is there any OpenSSL API which would give me the Key Type and its PEM
Length if I pass the buffer containing the Private Key in DER /PEM
format to it ??

Can anyone tell me how to get the Private Key Type(DSA /RSA ) and its
PEM Length  given the buffer containing the Private Key in PEM / DER
format.

Thanks in Advance,
Sudhir.
