Pkcs11-tool Generate Key Pair

An Online RSA Public and Private Key Generator. I was recently in a meeting where a person needed to generate a private and public key for RSA encryption, but they were using a PC (Windows). Generate a new key pair (public and private pair.) -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).

This will generate a public and private key pair. The keyspec consist of the key type, rsa or dsa (depends on what your card supports), and optinally a slash followed by the keysize in bits. 'rsa/1024' specifies a 1024-bit RSA key pair. Note: dsa is not fully supported. 2.1.5 X9.31 RSA key pair generation. The X9.31 RSA key pair generation mechanism, denoted CKMRSAX931KEYPAIRGEN, is a key pair generation mechanism based on the RSA public-key cryptosystem, as defined in X9.31. It does not have a parameter.

A public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which requires two separate keys, one of which is secret (or private) and one of which is public.1 Together they are known as a key-pair. In SSH, the public key cryptography is used in both directions (client to server and server to client.

NAME

pkcs11-tool - utility for managing and using PKCS #11 security tokens

SYNOPSIS

pkcs11-tool [OPTIONS]

DESCRIPTION

Thepkcs11-toolutility 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-frompath

Extract information frompath(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--loginunlock in logged in session; otherwise--login-typehas to be 'context-specific').

--hash, -h

Hash some data.

--idid, -did

Specify the id of the object to operate on.

--init-pin

Initializes the user PIN. This option differs from--change-pinin 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-filepath, -ipath

Specify the path to a file for input.

--keypairgen, -k

Generate a new key pair (public and private pair.)

--key-type <replacement>specification</replacement>

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).

--labelname, -aname

Specify the name of the object to operate on (or the token label when--init-tokenis 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

Pkcs11-tool
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').

--mechanismmechanism, -mmechanism

Use the specifiedmechanismfor token operations. See-Mfor a list of mechanisms supported by your token.

--modulemod

Specify a PKCS#11 module (or library) to load.

--moz-certpath, -zpath

Test a Mozilla-like keypair generation and certificate request. Specify thepathto the certificate file.

--output-filepath, -opath

Specify the path to a file for output.

--pinpin, -ppin

Use the givenpinfor token operations. If set to env:VARIABLE, the value of the environment variableVARIABLEis 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 variableVARIABLEis used.

This option will also set the--loginoption.

--pukpuk

Supply User PUK on the command line.

--new-pinpin

Supply new User PIN on the command line.

--set-idid, -eid

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.

--slotid

Specify the id of the slot to use.

--slot-descriptiondescription

Specify the description of the slot to use.

--slot-indexindex

Specify the index of the slot to use.

--token-labellabel

Specify the label of token. Will be used the first slot, that has the inserted token with this label.

--so-pinpin

Use the givenpinas the Security Officer PIN for some token operations (token initialization, user PIN initialization, etc). If set to env:VARIABLE, the value of the environment variableVARIABLEis used. The same warning as--pinalso applies here.

--test, -t

Perform some tests on the token. This option is most useful when used with either--loginor--pin.

--test-hotplug

Test hotplug capabilities (C_GetSlotList + C_WaitForSlotEvent).

--private

Set the CKA_PRIVATE attribute (object is only viewable after a login).

--test-ec

Test EC (best used with the--loginor--pinoption).

--test-fork

Test forking and calling C_Initialize() in the child.

--typetype, -ytype

Pkcs11-tool Generate Key Pair Key

Specify the type of object to operate on. Examples arecert,privkeyandpubkey.

--verbose, -v

Causepkcs11-toolto be more verbose.

NB! This does not affect OpenSC debugging level! To set OpenSC PKCS#11 module into debug mode, set theOPENSC_DEBUGenvironment variable to a non-zero number.

--read-object, -r

Get object's CKA_VALUE attribute (use with--type).

--delete-object, -b

Delete an object.

--application-labellabel

Pkcs11-tool Generate Key Pair Keyboard

Specify the application label of the data object (use with--typedata).

--application-idid

Specify the application ID of the data object (use with--typedata).

--issuerdata

Specify the issuer in hexadecimal format (use with--typecert).

--subjectdata

Pkcs11-tool
Specify the subject in hexadecimal format (use with--typecert/privkey/pubkey).

--signature-formatformat

Format for ECDSA signature: 'rs' (default), 'sequence', 'openssl'.

--write-objectid, -wpath

Write a key or certificate object to the token.pathpoints to the DER-encoded certificate or key file.
