+@cindex sign
+@item sign [@var{filename}]
+Sign a file with the local node's private key.
+If no @var{filename} is given, the file is read from standard input.
+The signed file is written to standard output.
+
+@cindex verify
+@item verify @var{name} [@var{filename}]
+
+Check the signature of a file against a node's public key.
+The @var{name} of the node must be given,
+or can be "." to check against the local node's public key,
+or "*" to allow a signature from any node whose public key is known.
+If no @var{filename} is given, the file is read from standard input.
+If the verification is succesful, a copy of the input with the signature removed is written to standard output, and the exit code will be zero.
+If the verification failed, nothing will be written to standard output, and the exit code will be non-zero.
