.Sh NAME
.Nm libpkcs11
.Nd PKCS#11 Cryptographic Framework library
.Sh SYNOPSIS
.Lb libpkcs11
.In security/cryptoki.h
.In security/pkcs11.h
.Sh DESCRIPTION
The
.Nm
library implements the RSA Security Inc. PKCS#11
Cryptographic Token Interface (Cryptoki), v2.40 specification by using plug-ins
to provide the slots.
.Lp
Each plug-in, which also implements RSA PKCS#11 v2.40, represents one or more
slots.
.Lp
The
.Nm
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
.Nm .
.Lp
The meta slot feature can be configured either system-wide or by individual
users.
System-wide configuration for meta slot features is done with the
.Xr cryptoadm 1M
utility.
User configuration for meta slot features is performed with environment
variables.
.Lp
By default, the following is the system-wide configuration for meta slot.
Meta slot is enabled.
Meta slot provides token-based object support with the Software RSA PKCS#11
softtoken
.Pq Xr pkcs11_softtoken 5 .
Meta slot is
allowed to move sensitive token objects to other slots if that is necessary to
perform an operation.
.Lp
Users can overwrite one or more system-wide configuration options for meta slot
using these environment variables.
.Lp
The
.Ev ${METASLOT_OBJECTSTORE_SLOT}
and
.Ev ${METASLOT_OBJECTSTORE_TOKEN}
environment variables are used to specify an alternate token object store.
A user can specify either slot-description in
.Ev ${METASLOT_OBJECTSTORE_SLOT}
or token-label in
.Ev ${METASLOT_OBJECTSTORE_TOKEN} , or both.
Valid values for slot-description and token-label are available from output of
the command:
.Bd -literal -offset indent
# cryptoadm list -v
.Ed
.Lp
The
.Ev ${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.
.Lp
The
.Ev ${METASLOT_AUTO_KEY_MIGRATE}
environment variable is used to specify
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.
.Lp
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.
.Lp
This library filters the list of mechanisms available from plug-ins based on
the policy set by
.Xr cryptoadm 1M .
.Lp
This library provides entry points for all PKCS#11 v2.40 functions.
See the PKCS#11 v2.40 specifications at
.Lk http://www.oasis-open.org.
.Lp
Plug-ins are added to
.Nm
by the
.Sy pkcs11conf
class action
script during execution of
.Xr pkgadd 1M .
The available mechanisms are administered by the
.Xr cryptoadm 1M
utility.
.Lp
Plug-ins must have all of their library dependancies specified, including
.Xr libc 3LIB .
Libraries that have unresolved symbols, including those from
.Xr libc 3LIB ,
will be rejected and a message will be sent to
.Xr syslog 3C
for such plug-ins.
.Lp
Due to U.S. Export regulations, all plug-ins are required to be
cryptographically signed using the
.Xr elfsign 1
utility.
.Lp
Any plug-in that is not signed or is not a compatible version of PKCS#11 will
be dropped by
.Nm .
When a plug-in is dropped, the administrator is alerted by the
.Xr syslog 3C
utility.
.Lp
The
.In security/pkcs11f.h
header contains function definitions.
The
.In security/pkcs11t.h
header contains type definitions.
Applications can include either of these headers in place of
.In security/pkcs11.h ,
which contains both function and type definitions.
.Sh INTERFACES
The shared object
.Pa libpkcs11.so.1
provides the public interfaces defined below.
See
.Xr Intro 3
for additional information on shared object interfaces.

.Sh NOTES
If an application calls
.Fn C_WaitForSlotEvent
without the
.Dv CKF_DONT_BLOCK
flag set,
.Nm
must create threads internally.
If, however,
.Dv CKF_LIBRARY_CANT_CREATE_OS_THREADS
is set,
.Fn C_WaitForSlotEvent
returns
.Dv CKR_FUNCTION_FAILED .
.Lp
The PKCS#11 library does not work with Netscape 4.\fIx\fR but does work with
more recent versions of Netscape and Mozilla.
.Lp
Because
.Fn 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
.Fn C_Finalize .
A library can be finished calling functions from
.Nm ,
while an application might not.
