76*0Sstevel@tonic-gate /*
77*0Sstevel@tonic-gate  * Briefly, a note on the APIs provided by this module.
78*0Sstevel@tonic-gate  *
79*0Sstevel@tonic-gate  * The sunw_PKCS_parse, parse_pkcs12 and sunw_PKCS12_contents APIs
80*0Sstevel@tonic-gate  * replace OpenSSL funcionality provided by PKCS12_parse and its
81*0Sstevel@tonic-gate  * supporting routines.
82*0Sstevel@tonic-gate  *
83*0Sstevel@tonic-gate  * The APIs provided here provide more functionality:
84*0Sstevel@tonic-gate  *
85*0Sstevel@tonic-gate  * - sunw_PKCS12_parse provides:
86*0Sstevel@tonic-gate  *
87*0Sstevel@tonic-gate  *   earlier MAC processing than PKCS12_parse
88*0Sstevel@tonic-gate  *
89*0Sstevel@tonic-gate  *   treats the handling of the difference between CA certs and certs
90*0Sstevel@tonic-gate  *   with matching private keys differently that PKCS12_parse does.  In
91*0Sstevel@tonic-gate  *   PKCS12_parse, any cert which is not the one selected is assumed to be
92*0Sstevel@tonic-gate  *   a CA cert.  In parse_pkcs12, certs which have matching private keys are
93*0Sstevel@tonic-gate  *   not returned as part of the CA certs.
94*0Sstevel@tonic-gate  *
95*0Sstevel@tonic-gate  *   the matching of private keys and certs is done at this level, rather than
96*0Sstevel@tonic-gate  *   at the lower levels which were used in the openssl implementation.  This
97*0Sstevel@tonic-gate  *   is part of the changes introduced so that the parsing functions can
98*0Sstevel@tonic-gate  *   return just a cert, just a private key, the stack of CA certs or any
99*0Sstevel@tonic-gate  *   combination.
100*0Sstevel@tonic-gate  *
101*0Sstevel@tonic-gate  *   added DO_FIRST_PAIR, DO_LAST_PAIR and DO_UNMATCHING matchty support.
102*0Sstevel@tonic-gate  *
103*0Sstevel@tonic-gate  *   do a much better job of cleaning up.  Specifically, free the added
104*0Sstevel@tonic-gate  *   attributes on the private key which was done by calling
105*0Sstevel@tonic-gate  *   sunw_evp_pkey_free().
106*0Sstevel@tonic-gate  *
107*0Sstevel@tonic-gate  *   in sunw_PKCS12_contents, handle allocation of the stacks of certificates
108*0Sstevel@tonic-gate  *   and private keys so that a) the original stacks are not changed unless
109*0Sstevel@tonic-gate  *   the parsing was successful; b) it will either extend stacks passed in,
110*0Sstevel@tonic-gate  *   or allocate new ones if none were supplied.
111*0Sstevel@tonic-gate  *
112*0Sstevel@tonic-gate  * - for parse_outer vs. parse_pk12() (from the openssl source base):
113*0Sstevel@tonic-gate  *
114*0Sstevel@tonic-gate  *   this calls lower levels with stacks of private keys and certs, rather
115*0Sstevel@tonic-gate  *   that a cert, a private key and a stack for CA certs.
116*0Sstevel@tonic-gate  *
117*0Sstevel@tonic-gate  * - In the case of parse_all_bags vs. parse_bags, there is no real difference,
118*0Sstevel@tonic-gate  *   other than use of stacks of private keys and certificates (as opposed
119*0Sstevel@tonic-gate  *   to one cert, one private key and a stack of CA certificates).
120*0Sstevel@tonic-gate  *
121*0Sstevel@tonic-gate  * - Finally, for parse_one_bag vs. parse_bag:
122*0Sstevel@tonic-gate  *
123*0Sstevel@tonic-gate  *   got rid of the bugs the openssl matching of keys and certificates.
124*0Sstevel@tonic-gate  *
125*0Sstevel@tonic-gate  *   got rid of the requirement that there is one private key and a matching
126*0Sstevel@tonic-gate  *   cert somewhere in the input.  This was done by moving the matching
127*0Sstevel@tonic-gate  *   code to a higher level.
128*0Sstevel@tonic-gate  *
129*0Sstevel@tonic-gate  *   put any localKeyID and/or friendlyName attributes found in the structures
130*0Sstevel@tonic-gate  *   returned, so that they can be used at higher levels for searching, etc.
131*0Sstevel@tonic-gate  *
132*0Sstevel@tonic-gate  *   added some error returns (like an error when there is an unsupported
133*0Sstevel@tonic-gate  *   bag type, an unsupported certificate type or an unsupported key type)
134*0Sstevel@tonic-gate  *
135*0Sstevel@tonic-gate  *   Added cleanup before returning.
