We have been hard at work adding server support for SCP to wolfSSH and it will be available in the next release of wolfSSH, version 1.3.0.
If you have an embedded device and want to securely upload a new firmware image to it or download a log file with the convenience of a copy command, wolfSSH has you covered. Our server API keeps it simple to receive or send files when a client connects using ciphers found in our lightweight crypto library, wolfCrypt.
If you are interested in FIPS, wolfSSH compiles against wolfCrypt and can use the wolfCrypt FIPS library. For more information about FIPS, contact fips@wolfssl.com and we can discuss your requirements and FIPS testing.
