- Problem solved
- OpenSSH solved the critical problem of insecure remote access to computer systems, which previously relied on protocols like Telnet, rlogin, and FTP that transmitted passwords and data in plaintext. This vulnerability made systems highly susceptible to eavesdropping and credential theft. OpenSSH provided strong encryption and robust authentication mechanisms to secure these communications.
- Platforms
- macOS, Unix-like operating systems (Linux, FreeBSD, OpenBSD, NetBSD, Solaris, AIX, HP-UX, etc.), Microsoft Windows (via Cygwin, Windows Subsystem for Linux, or built-in since Windows 10), Various embedded systems
