MacSSH is available for both 68K and PowerPC Macintoshes running at least System 7.5.1. You'll need Stuffit Expander version 5 or higher, freely available from AladdinSys to extract the binary from the downloaded archive.
You should first try the Stuffit file which has the same content as the BinHexed. If your browser starts displaying garbage, then hit the 'Back' button and try the BinHexed one.
