- Fully functioning SSH Server
- API and Development documentation
- Rapid Development support
- PeerSec Core Technology
System Requirements
- MatrixSSH does not require memory allocation, file system or multithread primitives
- Terminal emulator and shell language (bash, ksh, etc.) not required
- (Required) System or hardware source for random number generation
- (Required for Server) Time APIs
- (Optional) Use system malloc implementation rather than PeerSec Core Allocator
- (Optional) Read passwords, certificates and keys from files rather than memory
Supported Platforms
- MatrixSSH supports all operating systems and has been ported to OSs including VxWorks, eCos, Linux and Mac OS X
- MatrixSSH has been deployed on systems with no OS, filesystem or memory management.
- Ported platforms include ARM7 and i386.
