Hi Fred,
These functions i2d_X509_bio and d2i_X509_bio are used for X509 cerificates in DER format.
But the requirement was to read X509 cert in PEM format from memory.
Hi Steve,
I got ur point bio = BIO_new_mem_buf(cert, -1);
will be more efficient becuase it avoid BIO_write by just assinging memory pointer to BIO.
Thanks,
RSJ

Hi,
I think you could use the i2d_X509_bio and d2i_X509_bio function that help using BIO and X509 struture.
from openssl/x509.h
#define d2i_X509_bio(bp,x509) (X509 *)ASN1_d2i_bio((char *(*)())X509_new, \
(char *(*)())d2i_X509, (bp),(unsigned char **)(x509))
#define i2d_X509_bio(bp,x509) ASN1_i2d_bio(i2d_X509,bp,(unsigned char *)x509)
hope it could help
Fred

Its easier and more efficient to create the memory BIO with:
bio = BIO_new_mem_buf(cert, -1);
