### Dependencies
Portable OpenSSH is built using autoconf and make. It requires a working C compiler, standard library and headers, and [zlib](https://www.zlib.net/). ``libcrypto`` from either [LibreSSL](https://www.libressl.org/) or [OpenSSL](https://www.openssl.org) may also be used, but OpenSSH may be built without it supporting a subset of crypto algorithms.

[zlib](https://www.zlib.net/) is optional; without it transport compression is not supported.
FIDO security token support needs [libfido2](https://github.com/Yubico/libfido2) and its dependencies. Also, certain platforms and build-time options may require additional dependencies; see README.platform for details.
