NAME
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 configu-
ration 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-in-
teractively 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 initializa-
tion.
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 certifi-
cates, 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 op-
tions: 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 reg-
istered 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. Ac-
ceptable types are RSA, ECDSA, Ed25519, and DSA. Should be com-
bined 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 to-
ken. 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 fol-
lowing 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 op-
tion 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 ob-
ject
--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 to-
ken; 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.
Marks the object to be generated/written with the CKA_TRUST
flag.
--mark-distrusted
When retrieving objects, it requires the objects to be dis-
trusted (blacklisted). This option must not appear in combina-
tion with any of the following options: mark-trusted.

This is p11-kit trust module extension, thus this flag is only
valid with p11-kit registered trust modules.

no-mark-sign form will disable the option.
Marks the object to be generated/written with the CKA_SIGN flag
set to true.
--mark-ca, --no-mark-ca

CATE_CATEGORY as CA.
--mark-private, --no-mark-private
Marks the object to be written as private. The no-mark-private

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 cer-
tificate 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 cer-
tificate 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.
