NAME
pkcs11-tool - utility for managing and using PKCS #11 security tokens
SYNOPSIS
pkcs11-tool [OPTIONS]
DESCRIPTION
The pkcs11-tool utility is used to manage the data objects on smart cards and similar PKCS
#11 security tokens. Users can list and read PINs, keys and certificates stored on the
token. User PIN authentication is performed for those operations that require it.
OPTIONS
--attr-from filename
Extract information from filename (DER-encoded certificate file) and create the
corresponding attributes when writing an object to the token. Example: the certificate
subject name is used to create the CKA_SUBJECT attribute.
--change-pin, -c
Change the user PIN on the token
--unlock-pin
Unlock User PIN (without --login unlock in logged in session; otherwise --login-type
has to be 'context-specific').
--hash, -h
Hash some data.
--hash-algorithm mechanism
Specify hash algorithm used with RSA-PKCS-PSS signature or RSA-OAEP decryption.
Allowed values are "SHA-1", "SHA256", "SHA384", "SHA512", and some tokens may also
allow "SHA224". Default is "SHA-1".
Note that the input to RSA-PKCS-PSS has to be of the size equal to the specified hash
algorithm. E.g., for SHA256 the signature input must be exactly 32 bytes long (for
mechanisms SHA256-RSA-PKCS-PSS there is no such restriction). For RSA-OAEP, the
plaintext input size mLen must be at most keyLen - 2 - 2*hashLen. For example, for RSA
3072-bit key and SHA384, the longest plaintext to encrypt with RSA-OAEP is (with all
sizes in bytes): 384 - 2 - 2*48 = 286, aka 286 bytes.
--id id, -d id
Specify the id of the object to operate on.
--init-pin
Initializes the user PIN. This option differs from --change-pin in that it sets the
user PIN for the first time. Once set, the user PIN can be changed using --change-pin.
--init-token
Initialize a token: set the token label as well as a Security Officer PIN (the label
must be specified using --label).
--input-file filename, -i filename
Specify the path to a file for input.
--keypairgen, -k
Generate a new key pair (public and private pair.)
--keygen
Generate a new key.
--key-type specification
Specify the type and length of the key to create, for example rsa:1024 or
EC:prime256v1.
--usage-sign
Specify 'sign' key usage flag (sets SIGN in privkey, sets VERIFY in pubkey).
--usage-decrypt
Specify 'decrypt' key usage flag (RSA only, set DECRYPT privkey, ENCRYPT in pubkey).
--usage-derive
Specify 'derive' key usage flag (EC only).
--label name, -a name
Specify the name of the object to operate on (or the token label when --init-token is
used).
--list-mechanisms, -M
Display a list of mechanisms supported by the token.
--list-objects, -O
Display a list of objects.
--list-slots, -L
Display a list of available slots on the token.
--list-token-slots, -T
List slots with tokens.
--login, -l
Authenticate to the token before performing other operations. This option is not
needed if a PIN is provided on the command line.
--login-type
Specify login type ('so', 'user', 'context-specific'; default:'user').
--mechanism mechanism, -m mechanism
Use the specified mechanism for token operations. See -M for a list of mechanisms
supported by your token. The mechanism can also be specified in hexadecimal, e.g.,
0x80001234.
--mgf function
Use the specified Message Generation Function (MGF) function for RSA-PKCS-PSS
signatures or RSA-OAEP decryptions. Supported arguments are MGF1-SHA1 to MGF1-SHA512
if supported by the driver. The default is based on the hash selection.
--module mod
Specify a PKCS#11 module (or library) to load.
--moz-cert filename, -z filename
Test a Mozilla-like keypair generation and certificate request. Specify the filename
to the certificate file.
--output-file filename, -o filename
Specify the path to a file for output.
--pin pin, -p pin
Use the given pin for token operations. If set to env:VARIABLE, the value of the
environment variable VARIABLE is used. WARNING: Be careful using this option as other
users may be able to read the command line from the system or if it is embedded in a
script. If set to env:VARIABLE, the value of the environment variable VARIABLE is
used.
This option will also set the --login option.
--puk puk
Supply User PUK on the command line.
--new-pin pin
Supply new User PIN on the command line.
--sensitive
Set the CKA_SENSITIVE attribute (object cannot be revealed in plaintext).
--extractable
Set the CKA_EXTRACTABLE attribute (object can be extracted)
--set-id id, -e id
Set the CKA_ID of the object.
--show-info, -I
Display general token information.
--sign, -s
Sign some data.
--decrypt,
Decrypt some data.
--derive,
Derive a secret key using another key and some data.
--derive-pass-der,
Derive ECDHpass DER encoded pubkey for compatibility with some PKCS#11 implementations
--salt-len bytes
Specify how many bytes of salt should be used in RSA-PSS signatures. Accepts two
special values: "-1" means salt length equals to digest length, "-2" means use maximum
permissible length. Default is digest length (-1).
--slot id
Specify the id of the slot to use.
--slot-description description
Specify the description of the slot to use.
--slot-index index
Specify the index of the slot to use.
--object-index index
Specify the index of the object to use.
--token-label label
Specify the label of token. Will be used the first slot, that has the inserted token
with this label.
--so-pin pin
Use the given pin as the Security Officer PIN for some token operations (token
initialization, user PIN initialization, etc). If set to env:VARIABLE, the value of
the environment variable VARIABLE is used. The same warning as --pin also applies
here.
--test, -t
Perform some tests on the token. This option is most useful when used with either
--login or --pin.
--test-hotplug
Test hotplug capabilities (C_GetSlotList + C_WaitForSlotEvent).
--private
Set the CKA_PRIVATE attribute (object is only viewable after a login).
--always-auth
Set the CKA_ALWAYS_AUTHENTICATE attribute to a private key object. If set, the user
has to supply the PIN for each use (sign or decrypt) with the key.
--allowed-mechanisms mechanisms
Sets the CKA_ALLOWED_MECHANISMS attribute to a key objects when importing an object or
generating a keys. The argument accepts comma-separated list of algorithmsm, that can
be used with the given key.
--test-ec
Test EC (best used with the --login or --pin option).
--test-fork
Test forking and calling C_Initialize() in the child.
--type type, -y type
Specify the type of object to operate on. Valid value are cert, privkey, pubkey,
secrkey and data.
--verbose, -v
Cause pkcs11-tool to be more verbose.
NB! This does not affect OpenSC debugging level! To set OpenSC PKCS#11 module into
debug mode, set the OPENSC_DEBUG environment variable to a non-zero number.
--verify,
Verify signature of some data.
--read-object, -r
Get object's CKA_VALUE attribute (use with --type).
--delete-object, -b
Delete an object.
--application-label label
Specify the application label of the data object (use with --type data).
--application-id id
Specify the application ID of the data object (use with --type data).
--issuer data
Specify the issuer in hexadecimal format (use with --type cert).
--subject data
Specify the subject in hexadecimal format (use with --type cert/privkey/pubkey).
--signature-file filename
The path to the signature file for signature verification
--signature-format format
Format for ECDSA signature: 'rs' (default), 'sequence', 'openssl'.
--write-object filename, -w filename

certificate or key file.
--generate-random num
Get num bytes of random data.
EXAMPLES
To list all certificates on the smart card:
pkcs11-tool --list-objects --type cert
To read the certificate with ID KEY_ID in DER format from smart card:
pkcs11-tool --read-object --id KEY_ID --type cert --output-file cert.der
To convert the certificate in DER format to PEM format, use OpenSSL tools:
openssl x509 -inform DER -in cert.der -outform PEM > cert.pem
To sign some data stored in file data using the private key with ID ID and using the
RSA-PKCS mechanism:
pkcs11-tool --sign --id ID --mechanism RSA-PKCS --input-file data --output-file data.sig
