Topic: wc_InitRsaKey causes stack smashing
I'm trying to create an RSA keypair using the following code:
int main()
{
RsaKey rsakey;
printf("Memory allocated\n");
RNG rng;
wc_InitRng(&rng);
printf("Ring initialized\n");
wc_InitRsaKey(&rsakey, 0);
printf("RSA key initialized\n");
int ret = wc_MakeRsaKey(&rsakey, 1024, 65537, &rng);
printf("RSA key made\n");
if (ret != 0)
printf("Error creating RSA key\n");
else
printf("Successfully created the RSA key\n");
return 0;
}I have even placed the return 0 after the wc_MakeRsaKey line. When I run this program, I see the following output:
$ ./main
Memory allocated
Ring initialized
RSA key initialized
RSA key made
Successfully created the RSA key
*** stack smashing detected ***: <unknown> terminated
Aborted (core dumped)
I have tried including the wolfssl/wolfcrypt/rsa.h as well as the cyassl/ctaocrypt/rsa.h files, both seem to have the same problem.
I have downloaded the wolfssl3.9.6 file, configured it with
./configure --enable-keygen, I can verify the install with
wolfssl-config --versionThe code is compiled with the following Makefile (excerpt)
CC=gcc
CFLAGS=-c -Wall -I/usr/local/lib
all: main
main: main.o
$(CC) main.o -o main -lwolfssl
main.o: main.c
$(CC) $(CFLAGS) main.cIs there a step that I am missing? Why does this seem to always lead to stack smashing / seg faults?
Thanks for the help!
