## Name

pkcs11-keygen — generate keys on a PKCS#11 device

## Synopsis

`pkcs11-keygen` {-a `algorithm`} [`-b `keysize``] [`-e`] [`-i `id``] [`-m `module``] [`-P`] [`-p `PIN``] [`-q`] [`-S`] [`-s `slot``] {label}

## DESCRIPTION

pkcs11-keygen causes a PKCS#11 device to generate a new key pair with the given `label` (which must be unique) and with `keysize` bits of prime.

## ARGUMENTS

-a `algorithm`

  Specify the key algorithm class: Supported classes are RSA, DSA, DH, and ECC. In addition to these strings, the `algorithm` can be specified as a DNSSEC signing algorithm that will be used with this key; for example, NSEC3RSASHA1 maps to RSA, and ECDSAP256SHA256 maps to ECC. The default class is "RSA".

-b `keysize`

  Create the key pair with `keysize` bits of prime. For ECC keys, the only valid values are 256 and 384, and the default is 256.

-e

  For RSA keys only, use a large exponent.

-i `id`

  Create key objects with id. The id is either an unsigned short 2 byte or an unsigned long 4 byte number.

-m `module`

  Specify the PKCS#11 provider module. This must be the full path to a shared library object implementing the PKCS#11 API for the device.

-P

  Set the new private key to be non-sensitive and extractable. The allows the private key data to be read from the PKCS#11 device. The default is for private keys to be sensitive and non-extractable.

-p `PIN`

  Specify the PIN for the device. If no PIN is provided on the command line, pkcs11-keygen will prompt for it.

-q

  Quiet mode: suppress unnecessary output.

-S

  For Diffie-Hellman (DH) keys only, use a special prime of 768, 1024 or 1536 bit size and base (aka generator) 2. If not specified, bit size will default to 1024.

-s `slot`

  Open the session with the given PKCS#11 slot. The default is slot 0.
