a signature verifying command interpreter
Shell Perl Makefile
Branch: master


 * merge changes from Y!:
   * change '-c' to '-f', since login shells might get invoked with '-c',
     which opens up the possibility of allowing a user to provide their
     own certificate via 'ssh host -- /dev/tty'
   * correct error reporting, since verifyArgs() is executed in a subshell
   * quote args to verifyArgs

sigsh is a non-interactive, signature requiring and verifying command
interpreter. More accurately, it is a signature verification wrapper
around a given shell. It reads input in PKCS#7 format from standard in,
verifies the signature and, if the signature matches, pipes the decoded
input into the command interpreter.
