ssheven
-------
A modern SSH client for Mac OS 7/8/9.

Project status: as of 0.8.0 ([see github releases](https://github.com/cy384/ssheven/releases)), a functional SSH client, able to connect via key or password.  Versions prior to 1.0.0 are alpha/beta quality.

system requirements
-------------------
* CPU: Any PPC processor, or at least a 25 MHz 68040/68LC040.  Presently, all 68030 and 68020 CPUs are too slow.
* RAM: 2MB.
* Disk space: 1MB for the fat binary.
* System 7.5 or later, possibly earlier System 7 with the Thread Manager extension.
* Open Transport networking required, latest version possible highly recommended.

roadmap
-------
0.9.0
* general ssheven code cleanup
* select words on double click
* font face and size options

1.0.0 (first "real" release)
* nicer error presentation for more failure cases
* add `known_hosts` reset option
* read Apple HIG and clean up UI/UX
* license info in an about box type thing
* finish and upload papercraft box, floppy sticker artwork, icon/logo svg
* configurable terminal string

known bugs
* initial key exchange is too slow for 68030 machines (improve `mbedtls_mpi_exp_mod` and BN assembly) (needs 5x speed improvement for 68030)
* input latency feels high because redrawing the screen is slow
* receiving a large amount of data breaks the channel (e.g. `cat /dev/zero`)
* excessive redraws/flicker while selecting
* non-US keyboard input has issues
* custom colors are a little wonky

possible upcoming features
* scp file transfer
* more complete color support (currently uses an 8-color hack)
* keyboard-interactive authentication

build
-----
Uses Retro68 and cmake.

Requires mbedtls, libssh2, and libvterm, see my (cy384's) ports of those libraries for details.  Note that you need to build/install each for both platforms (m68k and PPC).

To build a fat binary, edit `build-ssheven.bash` with the path to your Retro68 build, and then run it.
