5.3.8 Invoking p11tool

Program that allows operations on PKCS #11 smart cards and security modules.

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’.

You can provide the PIN to be used for the PKCS #11 operations with the environment variables GNUTLS_PIN and GNUTLS_SO_PIN.

This section was generated by AutoGen, using the agtexi-cmd template and the option descriptions for the p11tool program. This software is released under the GNU General Public License, version 3 or later.

p11tool help/usage (--help)

This is the automatically generated usage text for p11tool.

The text printed is the same whether selected with the help option (--help) or the more-help option (--more-help). more-help will print the usage text by passing it through a pager program. more-help is disabled on platforms without a working fork(2) function. The PAGER environment variable is used to select the program, defaulting to more. Both will exit with a status code of 0.

p11tool Examples

To view all tokens in your system use:

$ p11tool --list-tokens

To view all objects in a token use:

$ p11tool --login --list-all "pkcs11:TOKEN-URL"

To store a private key and a certificate in a token run:

$ p11tool --login --write "pkcs11:URL" --load-privkey key.pem \
          --label "Mykey"
$ p11tool --login --write "pkcs11:URL" --load-certificate cert.pem \
          --label "Mykey"

Note that some tokens require the same label to be used for the certificate and its corresponding private key.

To generate an RSA private key inside the token use:

$ p11tool --login --generate-privkey rsa --bits 1024 --label "MyNewKey" \
          --outfile MyNewKey.pub "pkcs11:TOKEN-URL"

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.

certtool --generate-request --load-privkey "pkcs11:KEY-URL" \
   --load-pubkey MyNewKey.pub --outfile request.pem
