QUESTION
I am trying include different IPSec algorithms in C++ based application program. In that I wanted to use AES-XCBC algorithm described here: http://www.faqs.org/rfcs/rfc3566.html
I looked at OpenSSL's API's but did not find suitable ones for AES-XCBC like one for AES_GCM described in OpenSSL's wiki: https://www.openssl.org/docs/man1.1.0/man3/EVP_EncryptInit_ex.html
But was able to find this test program from OpenSwan library: https://github.com/xelerance/Openswan/blob/6055fc6fa444f3d5b89ad0f7d3ec277eedaa9282/lib/libcrypto/libaes/test_main_mac.c
I modified the program to use 2nd test vector from algorithm description link in RFC 3566 like:

QUESTION
I'm trying to configure OpenSwan, an open source IPsec solution written in C.
I have a script to download a configuration file ipsec.conf on an Amazon Linux EC2 that was created on my Macbook and uploaded to S3.
When I start the ipsec service, it segfaults.
Curiously, if I open the configuration file with VIM, make no changes, and simply write/quit, it works. This lends me to believe somehow the file has some weird characters/formatting.
I know of dos2unix, which I ran on the configuration file but that did not prevent the segfault.
I'm wondering what exactly VIM is doing when I write/quit. I could script that operation on my configuration file after pulling it. Or anything else that would help me understand what's going on.
...ANSWER
Answered 2017-Aug-23 at 22:34First, try to open the file with vim, then exit vim (:q) without having saved the file before. If vim says File modified since last complete write; write or use ! to override., this means that this is not something that vim does when write/quit that changes your file, but that this is something that vim does when it opens the file. And this is the most common case.
Vim parses the input file depending on the locale, and if some characters can not be understood according to the locale, vim may forget them. So, when saving the file, those characters will be removed.
Now, use vim to save your file as ipsec-ok.conf.
And run the following command:
