PEM_read_RSAPublicKey

[Z. S.Ghand]

Hi ,

I have written this simple function to read server certificate, but it always return -1.

int  RSAEncryptPublickey(unsigned char *from , unsigned char *to)
{
     assert( from && to );
     unsigned char * rsa = new unsigned char ;
     FILE * fp = fopen(PublickeyFile , "rb" ) ;
    
     if ( !fp ) return -2 ;
     rsa = (unsigned char *) PEM_read_RSAPublicKey( fp,(RSA **) rsa , 0 ,NULL);
     fclose( fp ) ;
     if ( !rsa )    
          return -1; 
          
 
     return RSA_public_encrypt ( (int ) strlen ( (char *) from ) , from , to , rsa ,RSA_PKCS1_PADDING );
}

 

would you please help me what should i do ?

 

thank
