I can't tell which debian 8.4 package provides the C headers for OpenSSL, the "Usual suspects" such as openssl-devel and the like do not exist, dpkg-query doesn't seem to find anything likely. Would some kind person give me a clue where to find the OpenSSL C header files in the Debian packaging universe?

Many thanks....Nick G

Not sure what you exactly mean, but I use this
dpkg -L libssl-dev:amd64

$ apt-cache show libssl-dev
Package: libssl-dev

Thanks very much, that was the correct name: libssl-dev, not openssl-dev or similar...Nick

In general, use apt-cache search to find packages when you don't know
the exact names.

$ apt-cache search --names-only ssl dev
libace-inet-ssl-dev - ACE SSL-enabled Inet protocol library - development files
libace-ssl-dev - ACE secure socket layer library - development files
libcurl4-openssl-dev - development files and documentation for libcurl (OpenSSL flavour)
libglobus-gsi-openssl-error-dev - Globus Toolkit - Globus OpenSSL Error Handling Development Files
libglobus-gsi-proxy-ssl-dev - Globus Toolkit - Globus GSI Proxy SSL Library Development Files
libglobus-openssl-module-dev - Globus Toolkit - Globus OpenSSL Module Wrapper Development Files
libgnutls28-dev - GNU TLS library - development files
liblwt-ssl-ocaml-dev - cooperative OpenSSL bindings for OCaml
libnussl-dev - The authenticating firewall [SSL development files]
libssl-ocaml-dev - OCaml bindings for OpenSSL
libocamlnet-ssl-ocaml-dev - OCaml application-level Internet libraries - SSL development libraries
libssl-dev - Secure Sockets Layer toolkit - development files
libpolarssl-dev - lightweight crypto and SSL/TLS library

It takes a bit of effort to scan the list, of course, and a bit of
experience to know which names you can immediately throw away.

Once you narrow down the list to a few possible names, use apt-cache show
to see the descriptions:

$ apt-cache show libssl-dev
