At this point Buildroot doesn't allow to use mbedTLS crypto backend even though libssh supports it. In case of fully statically linked ELF executables the size difference between OpenSSL and mbedTLS is significant: it matters for embedded targets with very limited storage. This patch adds support for compiling libssh with mbedTLS as a crypto backend. It also allows the selection of the crypto backend libssh will use through a choice in the package config, similar to libssh2. Currently, the selection of the backend is based on a priority order, which is not always desirable, as in some cases multiple backends can exists at the same time for various reasons.

libssh is a multiplatform C library implementing the SSHv2
|
|
and SSHv1 protocol on client and server side. With libssh,
|
|
you can remotely execute programs, transfer files, use a
|
