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.

Options

-a algorithm

This option specifies the key algorithm class: supported classes are RSA, DSA, DH, ECC, and ECX. In addition to these strings, the algorithm can be specified as a DNSSEC signing algorithm to be used with this key; for example, NSEC3RSASHA1 maps to RSA, ECDSAP256SHA256 maps to ECC, and ED25519 to ECX. The default class is RSA.

-b keysize

This option creates the key pair with keysize bits of prime. For ECC keys, the only valid values are 256 and 384, and the default is 256. For ECX keys, the only valid values are 256 and 456, and the default is 256.

-e

For RSA keys only, this option specifies use of a large exponent.

-i id

This option creates key objects with id. The ID is either an unsigned short 2-byte or an unsigned long 4-byte number.

-m module

This option specifies 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

This option sets the new private key to be non-sensitive and extractable, and 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

This option specifies the PIN for the device. If no PIN is provided on the command line, pkcs11-keygen prompts for it.

-q

This option sets quiet mode, which suppresses unnecessary output.

-S

For Diffie-Hellman (DH) keys only, this option specifies use of a special prime of 768-, 1024-, or 1536-bit size and base (AKA generator) 2. If not specified, bit size defaults to 1024.

-s slot

This option opens the session with the given PKCS#11 slot. The default is slot 0.
