.SH NAME
pkcs15-tool \- utility for manipulating PKCS #15 data structures on smart cards and similar security tokens
.SH SYNOPSIS
\*(nm
.RI [OPTIONS]
.SH DESCRIPTION
The \*(nm utility is used to manipulate the PKCS #15
data structures on smart cards and similar security tokens.  
Users can list and read PINs, keys and
certificates stored on the token.  User PIN authentication is
performed for those operations that require it.
.SH OPTIONS
.TP
.BR \-\-learn\-card ", " \-L
Cache PKCS #15 token data to the local filesystem.  Subsequent 
operations are performed on the cached data where possible.  If
the cache becomes out\-of\-sync with the token state (eg. new
key is generated and stored on the token), the cache should
be updated or operations may show stale results.
.TP
.BR "\-\-read\-certificate " \fIcert\fP ", \-r " \fIcert\fP
Reads the certificate with the given id.
.TP
.BR \-\-list\-certificates ", " \-c
Lists all certificates stored on the token.
.TP
.BR \-\-list\-pins
Lists all PINs stored on the token.  General information about
each PIN is listed (eg. PIN name).  Actual PIN values are not shown.
.TP
.BR \-\-change\-pin
Changes a PIN stored on the token.  User authentication is required
for this operation.
.TP
.BR \-\-list\-keys ", " \-k
Lists all private keys stored on the token.  General information about
each private key is listed (eg. key name, id and algorithm).  Actual private
key values are not displayed.
.TP
.BR \-\-list\-public\-keys
Lists all public keys stored on the token, including key name, id,
algorithm and length information.
.TP
.BR "\-\-read\-public\-key " \fIid\fP
Reads the public key with id \fIid\fP, allowing the user to
extract and store or use the public key.
.TP
.BR "\-\-output " \fIfilename\fP ", \-o " \fIfilename\fP
Specifies where key output should be written.  If \fIfilename\fP already
exists, it will be overwritten.  If this option is not given, keys will
be printed to standard output.
.TP
.BR \-\-no\-cache
Disables token data caching.
.TP
.BR "\-\-pin\-id " \fIpin\fP ", \-a " \fIpin\fP
Specifies the auth id of the PIN to use for the operation.  This
is useful with the \-\-change\-pin operation.
.TP
.BR "\-\-reader " \fInum\fP
Forces \*(nm to use reader number \fInum\fP for operations.  The default
is to use reader number 0, the first reader in the system.
.TP
.BR \-\-verbose ", " \-v
Causes \*(nm to be more verbose. Specify this flag several times
to enable debug output in the opensc library.
