.SH NAME
signfile \- signs a data file
.SH SYNOPSIS

signfile [<options>] <key handle> <input file> <output file>

.SH DESCRIPTION
This command will perform an RSA digital signature operation on an
input file.
Since the file is hashed, a file of any size may be signed.
.SH ARGUMENTS
.TP 5
key handle
is an 8-hex-digit number that specifies the TPM handle assigned to the
key that is to be used for signing.
It is
usually obtained from the \fBloadkey\fP utility
when the key was loaded into the TPM.  A signing-type key must be used.
.TP 5
input file
is the name of the file containing the data to be signed.
.TP 5
output file
This specifies the name of the output file, which contains the signed data.
.SH OPTIONS
The following command line options are supported...
.TP 5                
-k <keypass>
specifies the key usage password,
which is any character string, up to 256 bytes long.
It specifies the password needed to use the key that signs the file.
The actual "Authorization Data"
passed to the TPM is the 20 byte SHA1 hash of the user-specified password.
