NNOOTTEESS The parameters nniidd__kkeeyy, nniidd__cceerrtt, iitteerr, mmaacc__iitteerr and kkeeyyttyyppee can all be set to zero and sensible defaults will be used. These defaults are: 40 bit RC2 encryption for certificates, triple DES encryption for private keys, a key iteration count of PKCS12_DEFAULT_ITER (currently 2048) and a MAC iteration count of 1. The default MAC iteration count is 1 in order to retain compatibility with old software which did not interpret MAC iteration counts. If such compatibility is not required then mmaacc__iitteerr should be set to PKCS12_DEFAULT_ITER. kkeeyyttyyppee adds a flag to the store private key. This is a non standard extension that is only currently interpreted by MSIE. If set to zero the flag is omitted, if set to KKEEYY__SSIIGG the key can be used for signing only, if set to KKEEYY__EEXX it can be used for signing and encryption. This option was useful for old export grade software which could use signing only keys of arbitrary size but had restrictions on the permissible sizes of keys which could be used for encryption. NNEEWW FFUUNNCCTTIIOONNAALLIITTYY IINN OOPPEENNSSSSLL 00..99..88 Some additional functionality was added to _P_K_C_S_1_2___c_r_e_a_t_e_(_) in OpenSSL 0.9.8. These extensions are detailed below. If a certificate contains an aalliiaass or kkeeyyiidd then this will be used for the corresponding ffrriieennddllyyNNaammee or llooccaallKKeeyyIIDD in the PKCS12 structure. Either ppkkeeyy, cceerrtt or both can be NNUULLLL to indicate that no key or certficate is required. In previous versions both had to be present or a fatal error is returned. nniidd__kkeeyy or nniidd__cceerrtt can be set to -1 indicating that no encryption should be used. mmaacc__iitteerr can be set to -1 and the MAC will then be omitted entirely.
