11.Sh NAME
12.Nm libpkcs11
13.Nd PKCS#11 Cryptographic Framework library
14.Sh SYNOPSIS
15.Lb libpkcs11
16.In security/cryptoki.h
17.In security/pkcs11.h
18.Sh DESCRIPTION
19The
20.Nm
21library implements the RSA Security Inc. PKCS#11
22Cryptographic Token Interface (Cryptoki), v2.40 specification by using plug-ins
23to provide the slots.
24.Lp
25Each plug-in, which also implements RSA PKCS#11 v2.40, represents one or more
26slots.
27.Lp
28The
29.Nm
30library provides a special slot called the meta slot.
31The meta slot provides a virtual union of capabilities of all other slots.
32When available, the meta slot is always the first slot provided by
33.Nm .
34.Lp
35The meta slot feature can be configured either system-wide or by individual
36users.
37System-wide configuration for meta slot features is done with the
38.Xr cryptoadm 8
39utility.
40User configuration for meta slot features is performed with environment
41variables.
42.Lp
43By default, the following is the system-wide configuration for meta slot.
44Meta slot is enabled.
45Meta slot provides token-based object support with the Software RSA PKCS#11
46softtoken
47.Pq Xr pkcs11_softtoken 7 .
48Meta slot is
49allowed to move sensitive token objects to other slots if that is necessary to
50perform an operation.
51.Lp
52Users can overwrite one or more system-wide configuration options for meta slot
53using these environment variables.
54.Lp
55The
56.Ev ${METASLOT_OBJECTSTORE_SLOT}
57and
58.Ev ${METASLOT_OBJECTSTORE_TOKEN}
59environment variables are used to specify an alternate token object store.
60A user can specify either slot-description in
61.Ev ${METASLOT_OBJECTSTORE_SLOT}
62or token-label in
63.Ev ${METASLOT_OBJECTSTORE_TOKEN} ,
64or both.
65Valid values for slot-description and token-label are available from output of
66the command:
67.Bd -literal -offset indent
68# cryptoadm list -v
69.Ed
70.Lp
71The
72.Ev ${METASLOT_ENABLED}
73environment variable is used to specify whether
74the user wants to turn the metaslot feature on or off.
75Only two values are recognized.
76The value "true" means meta slot will be on.
77The value "false" means meta slot will be off.
78.Lp
79The
80.Ev ${METASLOT_AUTO_KEY_MIGRATE}
81environment variable is used to specify
82whether the user wants sensitive token objects to move to other slots for
83cryptographic operations.
84Only two values are recognized.
85The value "true" means meta slot will migrate sensitive token objects to other
86slots if necessary.
87The value "false" means meta slot will not migrate sensitive token objects to
88other slots even if it is necessary.
89.Lp
90When the meta slot feature is enabled, the slot that provides token-based
91object support is not shown as one of the available slots.
92All of its functionality can be used with the meta slot.
93.Lp
94This library filters the list of mechanisms available from plug-ins based on
95the policy set by
96.Xr cryptoadm 8 .
97.Lp
98This library provides entry points for all PKCS#11 v2.40 functions.
99See the PKCS#11 v2.40 specifications at
100.Lk http://www.oasis-open.org .
101.Lp
102Plug-ins are added to
103.Nm
104by the
105.Sy pkcs11conf
106class action
107script during execution of
108.Xr pkgadd 8 .
109The available mechanisms are administered by the
110.Xr cryptoadm 8
111utility.
112.Lp
113Plug-ins must have all of their library dependencies specified, including
114.Xr libc 3LIB .
115Libraries that have unresolved symbols, including those from
116.Xr libc 3LIB ,
117will be rejected and a message will be sent to
118.Xr syslog 3C
119for such plug-ins.
120.Lp
121Due to U.S. Export regulations, all plug-ins are required to be
122cryptographically signed using the
123.Xr elfsign 1
124utility.
125.Lp
126Any plug-in that is not signed or is not a compatible version of PKCS#11 will
127be dropped by
128.Nm .
129When a plug-in is dropped, the administrator is alerted by the
130.Xr syslog 3C
131utility.
132.Lp
133The
134.In security/pkcs11f.h
135header contains function definitions.
136The
137.In security/pkcs11t.h
138header contains type definitions.
139Applications can include either of these headers in place of
140.In security/pkcs11.h ,
141which contains both function and type definitions.
142.Sh INTERFACES
143The shared object
144.Pa libpkcs11.so.1
145provides the public interfaces defined below.

232.Sh STANDARDS
233The PKCS#11 Standard functions conform to PKCS#11 Cryptographic Token
234Interface Profiles v2.40 Extended Provider.
235.Sh NOTES
236If an application calls
237.Fn C_WaitForSlotEvent
238without the
239.Dv CKF_DONT_BLOCK
240flag set,
241.Nm
242must create threads internally.
243If, however,
244.Dv CKF_LIBRARY_CANT_CREATE_OS_THREADS
245is set,
246.Fn C_WaitForSlotEvent
247returns
248.Dv CKR_FUNCTION_FAILED .
249.Lp
250Because
251.Fn C_Initialize
252might have been called by both an application and a
253library, it is not safe for a library or its plugins to call
254.Fn C_Finalize .
255A library can be finished calling functions from
256.Nm ,
257while an application might not.
