80 * sunw_PKCS12_create() creates a pkcs#12 structure and given component parts.
81 *
82 * Given one or more of user private key, user cert and/or other (CA) certs,
83 * return an encrypted PKCS12 structure containing them.
84 *
85 * Arguments:
86 * pass - Pass phrase for the pkcs12 structure and private key (possibly
87 * empty) or NULL if there is none. It will be used to encrypt
88 * both the private key(s) and as the pass phrase for the whole
89 * pkcs12 wad.
90 * pkeys - Points to stack of private keys.
91 * certs - Points to stack of client (public ke) certs
92 * cacerts - Points to stack of 'certificate authority' certs (or trust
93 * anchors).
94 *
95 * Note that any of these may be NULL.
96 *
97 * Returns:
98 * NULL - An error occurred.
99 * != NULL - Address of PKCS12 structure. The user is responsible for
100 * freeing the memory when done.
