I want to implement public key authentication with CA and smart card. OpenSSH have their own certificate format, which is not x509.
I have a server (SSHD) and a client. I already made public key authentication happen with CA… Continue reading SSH – Implementing OpenSSH Certificates with smartcards
I am trying to load a passphrase-protected private SSH key from a file using the cryptography Python module. However, I’m not exactly sure how to proceed. The following yields a Crypto.Util.Padding.PaddingError: Padding is incorrect. error… Continue reading Loading a passphrase-protected private SSH key from a file with the cryptography Python module
A set of 36-year-old vulnerabilities has been uncovered in the Secure Copy Protocol (SCP) implementation of many client applications that can be exploited by malicious servers to overwrite arbitrary files in the SCP client target directory unauthorized… Continue reading 36-Year-Old SCP Clients’ Implementation Flaws Discovered
