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.

−−initialize−pin Initializes/Resets a PKCS #11 token user PIN.

−−initialize−so−pin Initializes/Resets a PKCS #11 token security
officer PIN.

This initializes the security officer’s PIN. When used
non−interactively use the GNUTLS_NEW_SO_PIN environment variables to
initialize SO’s PIN.

−−set−pin=str Specify the PIN to use on token operations.

Alternatively the GNUTLS_PIN environment variable may be used.

−−set−so−pin=str 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.

All objects available in the token will be listed. That includes
objects which are potentially unaccessible using this tool.

−−list−all−certs List all available certificates in a token.

That option will also provide more information on the certificates, for
example, expand the attached extensions in a trust token (like
p11−kit−trust).

−−list−certs List all certificates that have an associated private key.

That option will only display certificates which have a private key
associated with them (share the same ID).

−−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−privkey=str Generate private-public key pair of given type.

Generates a private−public key pair in the specified token. Acceptable
types are RSA, ECDSA, Ed25519, and DSA. Should be combined with
−−sec−param or −−bits.

−−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.

NOTE: THIS OPTION IS DEPRECATED
−−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.

NOTE: THIS OPTION IS DEPRECATED
−−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.

NOTE: THIS OPTION IS DEPRECATED
−−bits=num 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=str Specify the curve used for EC key generation.

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

−−sec−param=security parameter Specify the security level.

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

Writing objects

−−set−id=str 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=str Set the CKA_LABEL for the specified by the URL object.
This option must not appear in combination with any of the following
options: write, set-id.

Modifies or sets the CKA_LABEL in the specified by the URL object

−−write Writes the loaded objects to a PKCS #11 token.

It can be used to write private, public keys, certificates or secret
keys to a token. Must be combined with one of −−load−privkey,
−−load−pubkey, −−load−certificate option.

When writing a certificate object, its CKA_ID is set to the same CKA_ID
of the corresponding public key, if it exists on the token; otherwise
it will be derived from the X.509 Subject Key Identifier of the
certificate. If this behavior is undesired, write the public key to the
token beforehand.

−−delete Deletes the objects matching the given PKCS #11 URL.

−−label=str Sets a label for the write operation.

−−id=str Sets an ID for the write operation.

Sets the CKA_ID to be set by the write operation. The ID should be
specified in hexadecimal format without a ’0x’ prefix.

−−mark−wrap, −−no−mark−wrap Marks the generated key to be a wrapping
key. The no−mark−wrap form will disable the option.

Marks the generated key with the CKA_WRAP flag.

−−mark−trusted, −−no−mark−trusted Marks the object to be written as
trusted. This option must not appear in combination with any of the
following options: mark-distrusted. The no−mark−trusted form will
disable the option.

−−mark−distrusted When retrieving objects, it requires the objects to
be distrusted. 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.

no−mark−ca form will disable the option.

Marks the object to be generated/written with the
CKA_CERTIFICATE_CATEGORY as CA.

−−mark−private, −−no−mark−private Marks the object to be written as
private. The no−mark−private form will disable the option.

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
