Using externally hosted OpenSSL libraries from
https://indy.fulgan.com/SSL/. These are officially linked to by the
upstream OpenSSL Wiki and hence considered trustworthy. In addition, we
check against the SHA256 sum of these packages to prevent inclusion of
manipulated libraries. Removing the pre-build libraries from this
repository.
