.TH UNTEA 1 "" "24 December 2000" "TEA Total"
.SH NAME
untea \- Decrypt files which were created with the \fBtea\fP program
.SH SYNOPSIS
\fBuntea\fP [ \fI\-a\fP ] [ \fI\-p pass\fP ] \fIkey\-file\fP
[ \fIinput\-file\fP ] [ \fIoutput\-file\fP ]
.SH DESCRIPTION
The \fBtea\fP program decrypts the specified input file, which must have been
created by the \fBtea\fP program, using the specified private key (which must be
the same as that which was used to encrypt the file), and places the result in
the specified output file. Either or both of \fIinput\-file\fP and
\fIoutput\-file\fP can be "\-" to specify standard in or out. If an
input file name is specified (and it is not "\-") but no output file name is
specifed, the output file name is constructed by removing the \fB\.tea\fP
extension from the end of the input file name. If neither \fIinput\-file\fP or
\fIoutput\-file\fP are specified, they are taken to be stdin and stdout.
.SS OPTIONS
.TP
\fI\-a\fP
Informs \fBuntea\fP that the input data is Base64 encoded (also known as "Ascii
armour"). Untea will search through the input and decode the contents of every
\fBTEA Total\fP Base64 envelope it finds, except when a filename (or "-" for
stdout) is specified on the command line, or no file names are contained in the
data blocks (this will be the case if they were encoded from stdin). In this
case it will only decode the first envelope it finds. The BUILD_BASE64 option
must have been enabled at compile time for this option to be available.
.TP
\fI\-h\fP
Displays the help message.
.TP
\fI\-p\fP
Specifies the password for the input key file when using a password protected
key, instead of being prompted to enter it interactively. Note that this option
should not be used on multi-user systems, as the option can be read from the
system process list. The BUILD_PPKEYS option must have been enabled at compile
time for this option to be available.
