p11tool — GnuTLS PKCS #11 tool

Synopsis

p11tool [-flags] [-flag [value]] [--option-name[[=| ]value]] [url]

Operands and options may be intermixed. They will be reordered.

Description

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.

Options

Tokens

--list-tokens
List all available tokens.
--list-token-urls
List the URLs available tokens.

This is a more compact version of --list-tokens.
--list-mechanisms
List all available mechanisms in a token.
--initialize
Initializes a PKCS #11 token.
--set-pin=string
Specify the PIN to use on token initialization.

Alternatively the GNUTLS_PIN environment variable may be used.
--set-so-pin=string
Specify the Security Officer's PIN to use on token initialization.

Alternatively the GNUTLS_SO_PIN environment variable may be used.

Object listing

--list-all
List all available objects in a token.
--list-all-certs
List all available certificates in a token.
--list-certs
List all certificates that have an associated private key.
--list-all-privkeys
List all available private keys in a token.

Lists all the private keys in a token that match the specified URL.
--list-privkeys
This is an alias for the --list-all-privkeys option.
--list-keys
This is an alias for the --list-all-privkeys option.
--list-all-trusted
List all available certificates marked as trusted.
--export
Export the object specified by the URL. This option must not appear in combination with any of the following options: export-stapled, export-chain, export-pubkey.
--export-stapled
Export the certificate object specified by the URL. This option must not appear in combination with any of the following options: export, export-chain, export-pubkey.

Exports the certificate specified by the URL while including any attached extensions to it. Since attached extensions are a p11-kit extension, this option is only available on p11-kit registered trust modules.
--export-chain
Export the certificate specified by the URL and its chain of trust. This option must not appear in combination with any of the following options: export-stapled, export, export-pubkey.

Exports the certificate specified by the URL and generates its chain of trust based on the stored certificates in the module.
--export-pubkey
Export the public key for a private key. This option must not appear in combination with any of the following options: export-stapled, export, export-chain.

Exports the public key for the specified private key
--info
List information on an available object in a token.
--trusted
This is an alias for the --mark-trusted option.
--distrusted
This is an alias for the --mark-distrusted option.

Key generation

--generate-rsa
Generate an RSA private-public key pair.

Generates an RSA private-public key pair on the specified token. Should be combined with --sec-param or --bits.
--generate-dsa
Generate a DSA private-public key pair.

Generates a DSA private-public key pair on the specified token. Should be combined with --sec-param or --bits.
--generate-ecc
Generate an ECDSA private-public key pair.

Generates an ECDSA private-public key pair on the specified token. Should be combined with --curve, --sec-param or --bits.
--bits=number
Specify the number of bits for the key generate. This option takes an integer number as its argument.

For applications which have no key-size restrictions the --sec-param option is recommended, as the sec-param levels will adapt to the acceptable security levels with the new versions of gnutls.
--curve=string
Specify the curve used for EC key generation.

Supported values are secp192r1, secp224r1, secp256r1, secp384r1 and secp521r1.

Specify the security level.

This is alternative to the bits option. Available options are [low, legacy, medium, high, ultra].

Writing objects

--set-id=string
Set the CKA_ID (in hex) for the specified by the URL object. This option must not appear in combination with any of the following options: write.

Modifies or sets the CKA_ID in the specified by the URL object. The ID should be specified in hexadecimal format without a '0x' prefix.
--set-label=string

Marks the object to be generated/written with the CKA_TRUST flag.
--mark-distrusted
When retrieving objects, it requires the objects to be distrusted (blacklisted). This option must not appear in combination with any of the following options: mark-trusted.

Ensures that the objects retrieved have the CKA_X_TRUST flag. This is p11-kit trust module extension, thus this flag is only valid with p11-kit registered trust modules.

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-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

Exit Status

One of the following exit values will be returned:

0 (EXIT_SUCCESS)
Successful program execution.
1 (EXIT_FAILURE)
The operation failed or the command syntax was not valid.
70 (EX_SOFTWARE)
libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you.
