Hi, I am working on some server code that uses openssl libcrypto for AES encryption of files. Perhaps I am doing the wrong thing or the right thing the wrong way, but I am trying to use the OpenSSL secure heap for key storage. I created a small program that follow what I was trying to do, below, but the gist of it is that the CRYPTO_secure_malloc_init call returns 0 on my system, which means it has failed according to the man page at: https://www.openssl.org/docs/man1.1.1/man3/CRYPTO_secure_malloc_init.html I tried to get an error message out to see why, but apparently one is not set. The output of the program is: "failed to init openssl secure heap the error may be (null)" I am using a Fedora linux system that is running as a VM under VMWare Fusion on Mac OS. Any clues as to why it might be failing? Am I doing the wrong thing by trying to use the secure heap for key storage? Any help is appreciated. Thanks, Clay -------------------- #include <openssl/crypto.h> #include <openssl/conf.h> #include <openssl/evp.h> #include <openssl/err.h> #include <openssl/ssl.h> #define OPENSSL_MIN_HEAP_SIZE 65536 int main(){ SSL_load_error_strings(); SSL_library_init (); OpenSSL_add_all_algorithms (); // Initialize the OPENSSL secure heap space for key storage int ret = CRYPTO_secure_malloc_init(OPENSSL_MIN_HEAP_SIZE, OPENSSL_MIN_HEAP_SIZE); if (ret == 0){ printf("failed to init openssl secure heap the error may be %s\n", ERR_reason_error_string(ERR_get_error())); } }
