.SH "DESCRIPTION"
Program that allows operations on PKCS #11 smart cards
and security modules. 
.sp
To use PKCS #11 tokens with GnuTLS the p11-kit configuration files need to be setup.
That is create a .module file in /etc/pkcs11/modules with the contents 'module: /path/to/pkcs11.so'.
Alternatively the configuration file /etc/gnutls/pkcs11.conf has to exist and contain a number
of lines of the form 'load=/usr/lib/opensc-pkcs11.so'.
.sp
You can provide the PIN to be used for the PKCS #11 operations with the environment variables
GNUTLS_PIN and GNUTLS_SO_PIN.
.sp

.SH EXAMPLES
To view all tokens in your system use:
.br
.in +4
.nf
$ p11tool \-\-list\-tokens
.in -4
.fi
.sp
To view all objects in a token use:
.br
.in +4
.nf
$ p11tool \-\-login \-\-list\-all "pkcs11:TOKEN\-URL"
.in -4
.fi
.sp
To store a private key and a certificate in a token run:
.br
.in +4
.nf
$ p11tool \-\-login \-\-write "pkcs11:URL" \-\-load\-privkey key.pem \
          \-\-label "Mykey"
$ p11tool \-\-login \-\-write "pkcs11:URL" \-\-load\-certificate cert.pem \
          \-\-label "Mykey"
.in -4
.fi
Note that some tokens require the same label to be used for the certificate
and its corresponding private key.
.sp
To generate an RSA private key inside the token use:
.br
.in +4
.nf
$ p11tool \-\-login \-\-generate\-privkey rsa \-\-bits 1024 \-\-label "MyNewKey" \
          \-\-outfile MyNewKey.pub "pkcs11:TOKEN\-URL"
.in -4
.fi
The bits parameter in the above example is explicitly set because some
tokens only support limited choices in the bit length. The output file is the
corresponding public key. This key can be used to general a certificate
request with certtool.
.br
.in +4
.nf
