Implement server-side support for sk-ecdsa U2F-backed keys (#142)
* Implement server-side support for sk-ecdsa U2F-backed keys
* Fix out-of-bounds read on normal ecdsa-sha2-[identifier] keys
* Fix one more potential out-of-bounds read
* Check if nistp256 curve is used in sk-ecdsa-sha2- key
It's the only allowed curve per PROTOCOL.u2f specification
* Implement server-side support for sk-ed25519 FIDO2-backed keys
* Keys with type sk-* make no sense as host keys, so they should be
disabled
* fix typo
* Make sk-ecdsa call buf_ecdsa_verify
This reduces code duplication, the SK code just handles the
different message format.
* Reduce sk specific code
The application id can be stored in signkey, then we don't need
to call sk-specific functions from svr-authpubkey
* Remove debugging output, which causes compilation errors with DEBUG_TRACE disabled
* Proper cleanup of sk_app

.TH dropbearconvert 1 .SH NAME dropbearconvert \- convert between Dropbear and OpenSSH private key formats .SH SYNOPSIS .B dropbearconvert .I input_type .I output_type .I input_file .I output_file .SH DESCRIPTION .B Dropbear and .B OpenSSH SSH implementations have different private key formats. .B dropbearconvert can convert between the two. .P Dropbear uses the same SSH public key format as OpenSSH, it can be extracted from a private key by using .B dropbearkey \-y .P Encrypted private keys are not supported, use ssh-keygen(1) to decrypt them first. .SH ARGUMENTS .TP .I input_type Either .I dropbear or .I openssh .TP .I output_type Either .I dropbear or .I openssh .TP .I input_file An existing Dropbear or OpenSSH private key file .TP .I output_file The path to write the converted private key file. For client authentication ~/.ssh/id_dropbear is loaded by default .SH EXAMPLE # dropbearconvert openssh dropbear ~/.ssh/id_rsa ~/.ssh/id_dropbear .SH AUTHOR Matt Johnston ([email protected]). .SH SEE ALSO dropbearkey(1), ssh-keygen(1) .P https://matt.ucc.asn.au/dropbear/dropbear.html
