Hi, OpenSSH 9.4 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is a bugfix release. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at

OpenSSH 9.6 has just been released. It will be available from the mirrors listed at https://www.openssh.com/ shortly.

Hi, I have made a patch for enabling the use of ECDSA keys in the PKCS#11 support of ssh-agent which will be of interest to other users. I have tested it with P-256 keys. P-384 and P-521 should work out-of-the box. The code is ready for non-FIPS curves (named or explicit), but OpenSSH currently limits ECDSA to those 3 curves. At high level it works like the support for RSA, but because of

Hello everyone, as you could have noticed over the years, there are several bugs for PKCS#11 improvement and integration which are slipping under the radar for several releases, but the most painful ones are constantly updated by community to build, work and make our lives better. I wrote some of the patches, provided feedback to others, or offered other help here on mailing list, but did not

What sort of keys do you have in mind here that can't be represented via PKCS#11? -d

Hello, PKCS#11 is a standard API interface that can be used in order to access cryptographic tokens. You can find the specification at http://www.rsasecurity.com/rsalabs/node.asp?id=2133, most smartcard and other cryptographic device vendors support PKCS#11, opensc also provides PKCS#11 interface. I can easily make the scard.c, scard-opensc.c and ssh-agent.c support PKCS#11. PKCS#11 is

Hello OpenSSH developers, A week ago I've posted a patch that enables openssh to work with PKCS#11 tokens. I didn't receive any comments regarding the patch or reply to my questions. In current software world, providing a security product that does not support standard interface for external cryptographic hardware makes the product obsolete. Please comment my patch, so I can know

Hi all, Thanks for all your hard work! I was particularly excited to see FIDO/U2F support in the latest release. I'd like to make the following bug report in ssh-agent's PKCS#11 support: Steps to reproduce: 1. Configure a smart card (e.g. Yubikey in PIV mode) as an SSH key. 2. Add that key to ssh-agent. 3. Remove that key from ssh-agent. 4. Add that key to ssh-agent. Expected results:

Hi, Is there any way to store HostKey in hardware (and delegate the related processing)? I have been using Roumen Petrov's x509 patch for clients, which works via an OpenSSL engine, but it does not seem to support server HostKey: http://roumenpetrov.info/pipermail/ssh_x509_roumenpetrov.info/2012q4/000019.html For PKCS#11, I have found an email on this list from a year back suggesting this

Right now, if I typo my PIN for a PKCS#11 token, I get the inscrutable message: $ ssh -I /path/to/module user at example.com Enter PIN for 'SSH key': C_Login failed: 160 I'd prefer to receive a more useful message: Login to PKCS#11 token failed: Incorrect PIN I've attached a patch that adds specific handling for three common error cases: Incorrect PIN, PIN too long or too

Hello all, as PKCS#11 URI became standard (RFC 7512), it would be good to be able to specify the keys using this notation in openssh. So far I implemented the minimal subset of this standard allowing to specify the URI for the ssh tool, in ssh_config and to work with ssh-agent. It does not bring any new dependency, provides unit and regress tests (while fixing agent-pkcs11 regress test). The

Upon trying to deploy such a workaround, I found that the call to ssh-agent(1) nowadays is hidden *ridiculously* deep in the GUI startup
