PKCS#11 tools
pkcs11-tools is a toolkit containing a bunch of small utilities to perform key management tasks on cryptographic tokens implementing a PKCS#11 interface.
It features a number of commands similar to the unix CLI utilities, such as ls, mv, rm, od, and more. It also has specific commands to generate keys, generate CSRs, import certificates and other files, in a fashion compatible with most implementations, including both IBM and Oracle JVMs. It is also able to interface with NSS libraries from mozilla.org.
Some features:
- support for DES, 3DES, AES, HMAC, RSA, DSA, DH, Elliptic curves (NIST curves, Edwards curves)
- generation of PKCS#10 (CSR) and self-signed certificates
- import of certificates, public keys, data files
- support for wrapping and unwrapping keys, for both symmetric and asymmetric keys
- support for templates during key creation, public key import, key wrapping and key unwrapping
- support for session key generation and direct wrapping under one or several keys, in a single command
- support for key rewrapping (i.e. key unwrapping and key wrapping)
News
October 2021
Version 2.5, that brings support for CKA_ALLOWED_MECHANISMS, on many key management commands: p11keygen, p11wrap, p11unwrap, p11rewrap, p11od, p11ls.
Note that the wrapped key grammar has changed; the grammar version number has been incremented to 2.2.
July 2021
Version 2.4, to support templates in many commands: p11keygen, p11importpubk, p11wrap, p11unwrap, p11od, p11ls. Keys created with a template can be wrapped, the template attributes will be carried.
Note that the wrapped key grammar has changed, and the grammar version number has been incremented to 2.1.
April 2021
Version 2.3, that adds extra options to p11kcv, so that tokens not supporting NULL-length HMAC computation can be also supported.
March 2021
Version 2.2 is slightly changing the layout of p11slotinfo. Edwards Curve support enhanced. The toolkit is also adapted to be packaged as a FreeBSD port.
January 2021
Version 2.1 brings support for Edwards Curve.
December 2020
The toolkit has reached v2.0. It features several major changes:
- it supports (and requires) OpenSSL v1.1.1+
- signing commands (
p11mkcert,p11reqandmasqreq) implement OpenSSL algorithm methods. This will enable supporting more algorithms in the future. - major overhaul of the wrapping/unwrapping system: it is now possible to perform double wrapping (aka enveloppe wrapping) with a single command, in a secure fashion
p11keygencan now generate a session key and wrap it under one or several wrapping keys- a new command,
p11rewrap, allows to unwrap a key and immediately rewrap in under one or several wrapping keys, in a secure fashion.
Introduction
To build the source code, simply execute (with appropriate privileges)
$ ./configure
$ make installTo list the methods available on a PKCS#11 token, use p11slotinfo, that will return the list of available mechanisms, together with allowed APIs.

-----END CERTIFICATE REQUEST-----Later, p11importcert can be used to import the certificate back to the keystore. Public keys can be imported using p11importpubk, and data files with p11importdata.
If you need to wrap or unwrap a key, you can use the command p11wrap:
$ p11wrap -w aes-wrapping -i rootca -a cbcpad >wrapped-key.wrap
key wrapping succeededThe key can be unwrapped later, reusing the wrapped-key.wrap file created earlier:
$ p11unwrap -f wrapped-key.wrap
key unwrapping succeededInstallation
The project can compile on many platforms, including Linux, AIX, Solaris. Using cross-compilers, it is also possible to compile for the Windows platform. Compilation under MacOS requires brew. Please refer to docs/INSTALL.md for installation instructions.
