It seems some OpenSSL have AES-CTR and some do not, even if the version
is new enough. I can reproduce the above. On my debian system
/usr/include/openssl/evp.h has:
#if 0
const EVP_CIPHER *EVP_aes_128_ctr(void);
#endif
The version is recent enough:
#define OPENSSL_VERSION_NUMBER 0x009080bfL
I believe we need to check that EVP_aes_128_ctr actually is present in
the library, so I've applied a patch to do that. Please test again.
I now recall that this was the reason I did not use OpenSSL's built-in
AES-CTR APIs but had to re-implement it. AES-CTR doesn't appear widely
available in OpenSSL in distributions, even if it is in OpenSSL
upstream.
