24 This is an internal library for use only by:
25 usr/src/cmd/cmd-crypto
29 The library and the header file are installed into the proto area but
30 are not included in any pacakges.
37 There are a number of common code components and general utility functions
38 needed that are shared by various userland parts of the crypto framework.
40 The originally approved ARC materials (PSARC/2001/488 & PSARC/2001/553)
41 didn't have a library that was included by all user land libraries,
44 The solution to this is to follow what other project teams have done in the
45 past and create a project private util library.
49 Any code that is generic enough to be shared by multiple parts of the
50 user crypto framework is eligible.
52 The current contents are:
54 2.1 Error & Debug Functions
60 These functions log debug or error information to stderr and/or
61 syslog or a file. Debug is off by default but the code is always
64 The cryptodebug_init() routine allows the caller to set a message
65 prefix for error and debug output.
67 The environment variable SUNW_CRYPTO_DEBUG determines wither or not
68 debug output is generated at run time, valid values are "syslog" or "stderr"
70 For example elfsign(1) could do:
72 cryptodebug_init("elfsign");
75 cryptoerror(LOG_STDERR, gettext("invalid number of arguments"));
77 This would cause an error message on stderr thus:
79 "elfsign: invalid number of arguments"
81 The first argument to cryptoerror is either LOG_STDERR or a syslog(3c)
82 priority. All messages include the PID and are logged at LOG_USER.
86 cryptodebug("scmd=request opts=%s", opts);
88 This would go to the location defined by $SUNW_CRYPTO_DEBUG, ie
89 syslog, stderr or not be generated at all.
91 2.2 PKCS#11 Mechanism Type to and from Strings
93 pkcs11_mech2str() and pkcs11_str2mech()
95 These functions use a table built at compile time from the contents of
96 the pkcs11t.h file to map mechanism numbers to the corresponding string
99 pkcs11_mech2str() returns a pointer to a string that should be free(3c)'d
104 digest(1), mac(1), encrypt(1), decrypt(1) for translating
105 command line args to mech numbers. They will need to
106 add the "CKM_" prefix before calling pkc11_str2mech()
108 cryptoadm(1m) for output to user, and for storing in pkcs11.conf
113 2.3 The "pkcs11.conf" configuration file Parsing code.
115 The "pkcs11.conf" configuration file parsing code and data structures are
117 cryptoadm(1m), libpkcs11(3crypto).
119 2.3.1 Data Structures:
121 #define MECH_ID_HEX_LEN 11 /* length of mechanism id in hex form */
123 typedef char libname_t[MAXPATHLEN];
124 typedef char midstr_t[MECH_ID_HEX_LEN];
126 /* The policy list for an entry in the config file */
127 typedef struct umechlist {
129 struct umechlist *next;
132 /* An entry in the pkcs11.conf file */
133 typedef struct uentry {
135 boolean_t flag_enabledlist; /* TRUE if an enabledlist */
136 umechlist_t *policylist; /* disabledlist or enabledlist */
140 /* The entry list for the entire pkcs11.conf file */
141 typedef struct uentrylist {
143 struct uentrylist *next;
149 extern int get_pkcs11conf_info(uentrylist_t **ppliblist);
151 Retrieve the user-level provider info from the pkcs11.conf file.
152 If successful, the result is returned from the ppliblist argument.
153 This function returns SUCCESS if successfully done; otherwise it returns
154 FAILURE. The caller should use free_uentrylist() to free the space
155 allocated for "ppliblist".
157 extern umechlist_t *create_umech(char *mechname);
159 Create one item of type umechlist_t with the mechanism name in hex form.
160 A NULL is returned when the input name is NULL or the heap memory is
161 insufficient. The Caller should use free_umechlist() to free the space
162 allocated for the returning data.
164 extern void free_uentrylist(uentrylist_t *ptr);
166 Free space allocated for an pointer to the struct "uentrylist_t".
168 extern void free_uentry(uentry_t *ptr);
170 Free space allocated for an pointer to the struct "uentry_t".
172 extern void free_umechlist(umechlist_t *ptr);
174 Free space allocated for an pointer to the struct "umechlist_t".
176 2.4 PKCS#11 Mechanism Type to key type
178 pkcs11_mech2keytype()
180 This function is used to get the key type for a mechanism.
184 encrypt(1), decrypt(1), and libpkcs11(3crypto) for getting
185 the key type when creating an object for use with a
188 2.5 PKCS#11 return code to string
192 This function returns a string representation of any given PKCS11 return
197 encrypt(1) and decrypt(1) uses this function for reporting errors.
199 2.5 PKCS#11 URI parsing code
204 This function parses a PKCS#11 URI and fills up a pkcs11_uri_t structure. It
205 also reads the PIN if the PKCS#11 URI specifies a passphrase dialog. The
206 pkcs11_uri_t is described in cryptoutil.h, explanation of the return codes for
207 the pkcs11_parse_uri() function is in the function's comment in pk11_uri.c. The
208 pkcs11_parse_uri() function allocates the URI's fields and the caller is
209 responsible for calling pkcs11_free_uri() after it's done with the URI
214 SunSSH will use the functions for parsing PKCS#11 URIs.
218 Code for cryptographic algorithms does not belong in here. That
219 comes from usr/src/common/<algorithm> since it is shared between user and
222 PKCS#11 header files although they are common to various parts of the
223 user land framework come from usr/src/pkcs11/include
225 4. Interface Taxonomy
227 Everything in this library is Project Private or Internal. The
228 exported symbols will all be marked as SUNWprivate_1.0 in the library
233 The initial design was to only use a static archive library to avoid
234 exposing a new interface (even though it is all private). However while
235 this is fine for initial delivery it creates difficulties later with
236 patching. As such a Dynamic version will be build.
238 Libraries for lint and header files will not be shipped in any Sun packages
239 since this is all Project Private. Similarly the abi_ file will not be
240 shipped even though a spec file will be used in the source gate.
244 At present all of the consumers of the library are in /usr/ so the
245 library is /usr/lib/{sparcv9}/libcryptoutil.so.1. If kcfd ever moves
246 to /lib/crypto/kcf as a result of PSARC/2002/117 allowing it, then
247 libcryptoutil needs to move as well.
