assertions
.Sh SYNOPSIS
.Nm keynote-sign
.Op Fl v
.Ar AlgorithmName
.Ar AssertionFile
.Ar PrivateKeyFile
.Sh DESCRIPTION
For details on
.Nm KeyNote ,
see the web page
.Bd -literal -offset indent
http://www.cis.upenn.edu/~keynote
.Ed
.Pp
.Nm keynote-sign
reads the assertion contained in
.Fa AssertionFile
and generates a signature specified by
.Fa AlgorithmName
using the private key stored in
.Fa PrivateKeyFile .
The private key is expected to be of the form output by
.Xr keynote-keygen 1 .
The private key algorithm and the
.Fa AlgorithmName
specified as an argument are expected to match. There is no requirement
for the internal or ASCII encodings to match.
Valid
.Fa AlgorithmName
identifiers are:
.Bl -tag -width indent
.It ``sig-dsa-sha1-hex:''
.It ``sig-dsa-sha1-base64:''
.It ``sig-rsa-sha1-hex:''
.It ``sig-rsa-sha1-base64:''
.It ``sig-rsa-md5-hex:''
.It ``sig-rsa-md5-base64:''
.El
.Pp
Notice that the trailing colon is required.
The resulting signature is printed in standard output. This can then
be added (via cut-and-paste or some script) at the end of the
assertion, in the
.Fa Signature
field.
.Pp
The public key corresponding to the private key in
.Fa PrivateKeyFile
is expected to already be included in the
.Fa Authorizer
field of the assertion, either directly or indirectly (i.e., through
use of a
.Fa Local-Init
attribute). Furthermore, the assertion must have a
.Fa Signature
field (even if it is empty), as the signature is computed on
everything between the
.Fa KeyNote-Version
and
.Fa Signature
keywords (inclusive), and the
.Fa AlgorithmName
string.
.Pp
If the
.Op Fl v
flag is provided,
.Nm keynote-sign
will also verify the newly-created signature using the
.Fa Authorizer
field key.
