## Name

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

## Synopsis

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

## DESCRIPTION

pkcs11-keygen causes a PKCS#11 device to generate a new RSA key pair with the specified `label` and with `keysize` bits of modulus.

## ARGUMENTS

-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.

-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.

-s `slot`

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

-e

  Use a large exponent.

-b `keysize`

  Create the key pair with `keysize` bits of modulus.

-l `label`

  Create key objects with the given label. This name must be unique.

-i `id`

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

-p `PIN`

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

## CAVEAT

Some PKCS#11 providers crash with big public exponent.
