similar to: Bug in KRL signature verification

Hello. I am trying to play through the following test scenario about certificate revocation on Ubuntu 18.04, which has OpenSSH of this version: OpenSSH_7.6p1 Ubuntu-4, OpenSSL 1.0.2n? 7 Dec 2017 1. A CA key is created ssh-keygen -t ed25519 -f ca 2. The CA public key is added to ~/.ssh/authorized_keys on some server: cert-authority ssh-ed25519 AAAA...e ca at yoga 3. A user key is created on a

Hi, In ssh_krl_from_blob(), krl.c:984, /* Record keys used to sign the KRL */ xrealloc(ca_used, nca_used + 1, sizeof(*ca_used)); ca_used[nca_used++] = key; The result of `xrealloc' is never assigned to `ca_used', which remains a null pointer. Will ca_used[...] crash?. Did I miss anything? Thanks. - xi

Hi! While reading through PROTOCOL.krl I came across "5. KRL signature sections". If my understanding is correct - and that's basically what I would like to get knocked down for if appropriate ;) - this is a way for SSHDs to ensure they only accept KRLs signed by a trusted CA. However, I cannot seem to find a way to actually _sign_ a KRL with ssh-keygen? The aforementioned

In sshconnect.c there are two global variables for server_version_string client_version_string. These are used just in a few functions and can easily be passed as parameters. Also, there is a strange construct, where their memory is allocated to the global pointers, then copies of these pointers are assigned to the kex structure. The kex_free finally frees them via cleanup of the kex

Hi Daminan! Hmmm... thought about a little... when i use -vvv with ssh-keygen -Qf i see "debug1:..." So i think, debug is compiled in. ssh-keygen --help gives me ssh-keygen -k -f krl_file [-u] [-s ca_public] [-z version_number] file ... so... option -z is not the serial of the certificate, it is the version-number of the KRL-File... My openssh-Verision from Debian is

I've architected this in a way that looks future proof at least to the openssl provider transition. What will happen in openssl 3.0.0 is that providers become active and will accept keys via URI. The current file mechanisms will still be available but internally it will become a file URI. To support the provider interface, openssl will have to accept keys by URI instead of file and may
