.SH "NAME"
openpgp-tool \- utility for accessing visible data OpenPGP smart cards and compatible tokens
.SH "SYNOPSIS"
.HP \w'\fBopenpgp\-tool\fR\ 'u
\fBopenpgp\-tool\fR [\fIOPTIONS\fR]
.SH "DESCRIPTION"
.PP
The
\fBopenpgp\-tool\fR
utility is used for accessing data from the OpenPGP v1\&.1 and v2\&.0 smart cards and compatible tokens like e\&.g\&. GPF CryptoStick v1\&.x, which might not be present in PKCS#15 objects but available in custom files on the card\&. The data can be printed on screen or used by other programs via environment variables\&.
.SH "OPTIONS"
.PP
.PP
\fB\-\-del\-key\fR \fIarg\fR
.RS 4
Delete key indicated by
\fIarg\fR\&.
\fIarg\fR
can be
1,
2,
3, or
all\&.
.RE
.PP
\fB\-\-do\fR \fIarg\fR, \fB\-d\fR \fIarg\fR
.RS 4
Dump private data object (DO) indicated by
\fIarg\fR\&.
\fIarg\fR
can be in the form
\fIx\fR,
10\fIx\fR, or
010\fIx\fR
to access
DO 010\fIx\fR, where
\fIx\fR
is
1,
2,
3, or
4\&.
.RE
.PP
\fB\-\-erase\fR, \fB\-E\fR
.RS 4
Erase (i\&.e\&. reset) the card\&.
.RE
.PP
\fB\-\-exec\fR \fIprog\fR, \fB\-x\fR \fIprog\fR
.RS 4
Execute the given program with data in environment variables\&.
.RE
.PP
\fB\-\-gen\-key\fR \fIarg\fR, \fB\-G\fR \fIarg\fR
.RS 4
Generate key with the ID given as
\fIarg\fR\&.
\fIarg\fR
can be one of
1,
2, or
3\&.
.RE
.PP
\fB\-\-help\fR, \fB\-h\fR
.RS 4
Print help message on screen\&.
.RE
.PP
\fB\-\-key\-length\fR \fIbitlength\fR, \fB\-L\fR \fIbitlength\fR
.RS 4
Specify the length of the key to be generated\&. If not given, it defaults to 2048 bit\&.
.RE
.PP
\fB\-\-pin\fR \fIstring\fR
.RS 4
The PIN text to verify\&. If set to env:\fIVARIABLE\fR, the value of the environment variable
\fIVARIABLE\fR
is used\&.
.RE
.PP
\fB\-\-pretty\fR
.RS 4
Print values in pretty format\&.
.RE
.PP
\fB\-\-raw\fR

.RE
.PP
\fB\-\-reader\fR \fInum\fR, \fB\-r\fR \fInum\fR
.RS 4
Specify the reader to use\&. By default, the first reader with a present card is used\&. If
\fInum\fR
is an ATR, the reader with a matching card will be chosen\&.
.RE
.PP
\fB\-\-user\-info\fR, \fB\-U\fR
.RS 4
Show card holder information\&.
.RE
.PP
\fB\-\-verify\fR \fIpintype\fR
