SYNOPSIS
cc [ flag... ] file... -lpkcs11 [ library... ]
#include <security/cryptoki.h>
#include <security/pkcs11.h>
DESCRIPTION
The libpkcs11 library implements the RSA Security Inc. PKCS#11 Crypto‐
graphic Token Interface (Cryptoki), v2.20 specification by using plug-
ins to provide the slots.
Each plug-in, which also implements RSA PKCS#11 v2.20, represents one
or more slots.
The libpkcs11 library provides a special slot called the meta slot. The
meta slot provides a virtual union of capabilities of all other slots.
When available, the meta slot is always the first slot provided by
libpkcs11. The order of the rest of the slots is not guaranteed and may
vary with every load of this library.
The meta slot feature can be configured either system-wide or by indi‐
vidual users. System-wide configuration for meta slot features is done
with the cryptoadm(1M) utility. User configuration for meta slot fea‐
tures is performed with environment variables.
By default, the following is the system-wide configuration for meta
slot. Meta slot is enabled. Meta slot provides token-based object sup‐
port with the Software RSA PKCS#11 softtoken (pkcs11_softtoken(5)).
Meta slot is allowed to move sensitive token objects to other slots if
that is necessary to perform an operation.
Users can overwrite one or more system-wide configuration options for
meta slot using these environment variables.
The ${METASLOT_OBJECTSTORE_SLOT} and ${METASLOT_OBJECTSTORE_TOKEN}
environment variables are used to specify an alternate token object
store. A user can specify either slot-description in ${METASLOT_OBJECT‐
STORE_SLOT} or token-label in ${METASLOT_OBJECTSTORE_TOKEN}, or both.
Valid values for slot-description and token-label are available from
output of the command:
cryptoadm list -v
The ${METASLOT_ENABLED} environment variable is used to specify whether
the user wants to turn the metaslot feature on or off. Only two values
are recognized. The value "true" means meta slot will be on. The value
"false" means meta slot will be off.
The ${METASLOT_AUTO_KEY_MIGRATE} environment variable is used to spec‐
ify whether the user wants sensitive token objects to move to other
slots for cryptographic operations. Only two values are recognized. The
value "true" means meta slot will migrate sensitive token objects to
other slots if necessary. The value "false" means meta slot will not
migrate sensitive token objects to other slots even if it is necessary.
When the meta slot feature is enabled, the slot that provides token-
based object support is not shown as one of the available slots. All of
its functionality can be used with the meta slot.
This library filters the list of mechanisms available from plug-ins
based on the policy set by cryptoadm(1M).
This library provides entry points for all PKCS#11 v2.20 functions. See
the RSA PKCS#11 v2.20 specification at http://www.rsasecurity.com.
Plug-ins are added to libpkcs11 by the pkcs11conf class action script
during execution of pkgadd(1M). The available mechanisms are adminis‐
tered by the cryptoadm(1M) utility.
Plug-ins must have all of their library dependancies specified, includ‐
ing libc(3LIB). Libraries that have unresolved symbols, including those
from libc, will be rejected and a message will be sent to syslog(3C)
for such plug-ins.
Due to U.S. Export regulations, all plug-ins are required to be crypto‐
graphically signed using the elfsign utility.
Any plug-in that is not signed or is not a compatible version of
PKCS#11 will be dropped by libpkcs11. When a plug-in is dropped, the
administrator is alerted by the syslog(3C) utility.
The <security/pkcs11f.h> header contains function definitions. The
<security/pkcs11t.h> header contains type definitions. Applications can
include either of these headers in place of <security/pkcs11.h>, which
contains both function and type definitions.

The SUNW Extension functions are MT-Safe. The PKCS#11 Standard func‐
tions are MT-Safe with exceptions. See Section 6.5.2 of RSA PKCS#11
v2.20.
The PKCS#11 Standard functions conform to PKCS#11 v2.20.

NOTES
If an application calls C_WaitForSlotEvent() without the CKF_DONT_BLOCK
flag set, libpkcs11 must create threads internally. If, however,
CKF_LIBRARY_CANT_CREATE_OS_THREADS is set, C_WaitForSlotEvent() returns
CKR_FUNCTION_FAILED.
The PKCS#11 library does not work with Netscape 4.x but does work with
more recent versions of Netscape and Mozilla.
Because C_Initalize() might have been called by both an application and
a library, it is not safe for a library or its plugins to call C_Final‐
ize(). A library can be finished calling functions from libpkcs11,
while an application might not.
