After updating to FreeBSD 12.0, I no longer see p5-openxpki binary package (for both amd64 and i386), although p5-openxpki-i18n-2.2.3 is still provided. According to Bug 233564 this port is actively maintained, and no takedown was mentioned in release notes, so I suppose said issue is just a mistake.
A note from maintainer. Have little understanding about how ports are selected to be represented in the central binary package repository, and who controls this selection. I can only speculate, that most probably binary packages are prepared mainly for default configuration of the freshly installed bare system. But you can not build port security/p5-openxpki on 12.0 with defaults. You have to alter default configuration by placing a line "DEFAULT_VERSIONS+= ssl=openssl" to the file /etc/make.conf. In other words, you have to rebuild all of your ports with openssl-1.0.2 from ports. (Note, that 12.0 has openssl-1.1.1 in a base system.) The reason why this is necessary, is a line "BROKEN_SSL= openssl111" in the port's Makefile. And the reason for the latter is a sad fact, that upstream still does not support openssl-1.1.x. At the moment I am working on this problem together with the upstream. But the story promises to be long, because a number of dependencies for this port also do not support openssl-1.1.x.
Consider this issue resolved (answered) with: "broken with openssl111, the openssl version in 12.0-RELEASE base, which is the root cause of a missing package, as it cannot be built.". Maintainer also provided a workaround (replacing openssl111 with openssl (1.0x) @Sergei Please re-open this issue with a patch for OpenSSL 1.1.x support when it's ready.
(In reply to Sergei Vyshenski from comment #1) > Have little understanding about how ports are selected to be represented in > the central binary package repository, and who controls this selection. The packages are generated by portmgr using poudriere using default configurations. So, anything that does not show up in 'make -V IGNORE' for that ARCH and OSVERSION will be published. Given that there are over 35,000 ports and more than a dozen supported combinations of ARCH and OSVERSION, it is not possible to adjust configurations for individual ports.
PR #241196 offers a version of openxpki, which build fine at both openssl 1.0 and 1.1.
