RE: segmentation fault printing x509 attributes

[Ignacio Amoeiro Bosch]

Hi,

Thanks for the response, I checked that and the headers match with the
library that im linking.

This is the contents of my make file:

CC = gcc
CP = /bin/cp
RM = rm -f
AUTHN_INCLUDE_DIR =include

OBJS = authn_api.o
DSO  = authn_api.so

GCC_FLAGS= -I$(AUTHN_INCLUDE_DIR) -I/root/openssl/include -c -fPIC -Wall

$(DSO): $(OBJS)
$(CC) -g -shared $(OBJS) /lib/libssl.so.1.0.0
/lib/libcrypto.so.1.0.0 -o $(DSO) -m32
$(OBJS): authn_api.c
$(CC) -g  $(GCC_FLAGS) -o $(OBJS) authn_api.c -m32


Another thing, How can I check that the readed X509 structure its
correct?

Regards

My guess would be that the OpenSSL headers you are compiling with don't
precisely match the library that you are linking to. Functions like
X509_get_version are macros that extract elements of the X509 structure.

segmentation fault printing x509 attributes

[Ignacio Amoeiro Bosch]

 
Hi,

 

I'm developing a custom module for Oracle Access Manager. It needs to read some 
attributes from a certificate. 


The following code Works in a standalone c program, but crash (with a seg 
fault) using it as a module. The crash occurs at line : X509_get_version(x), or 
any method that uses x

X509 *x = NULL;

BIO *mem =NULL;

FILE *fp;

 

fp = fopen("/tmp/testfilen_fn.txt","a+");

mem = BIO_new_mem_buf((void *)certificate,-1);

What is wrong?

 

 

Thanks
