[openssl-users] Read cer file failed

[Jerry OELoo]

Hi All:
I am reading cer file into X509 object,
http://SVRSecure-G3-aia.verisign.com/SVRSecureG3.cer

cert = d2i_X509_fp(fp, NULL);
it will return fail, as below

Error: error:0D07207B:asn1 encoding routines:ASN1_get_object:header too long
Lib: asn1 encoding routines
Func: ASN1_get_object
Reason: header too long

I use openssl to convert cer from DER format to PEM format it works
fine, So I think it is a DER format file, but why d2i_X509_fp() read
it failed.

Thanks!
