  o Minor features (OpenSSL bug workaround):
    - Work around a bug in OpenSSL 1.1.1a, which prevented the TLS 1.3
      key export function from handling long labels.  When this bug
      is detected, Tor will disable TLS 1.3.  We recommend upgrading to
      a version of OpenSSL without this bug when it becomes available.
      Closes ticket 28973.
Detect openssl bug 7712 and work around it. In theory it would be better to detect this bug in advance, but this approach is much simpler, and therefore safer to backport. This closes tor issue 28973. 2019-01-02 20:23:42 +01:00			`o Minor features (OpenSSL bug workaround):`
