5 PKCS12_parse - parse a PKCS#12 structure

16 PKCS12_parse() parses a PKCS12 structure.
18 B<p12> is the B<PKCS12> structure to parse. B<pass> is the passphrase to use.
19 If successful the private key will be written to B<*pkey>, the corresponding
20 certificate to B<*cert> and any additional certificates to B<*ca>.
24 Each of the parameters B<pkey>, B<cert>, and B<ca> can be NULL in which case
25 the private key, the corresponding certificate, or the additional certificates,
26 respectively, will be discarded.
27 If any of B<pkey> and B<cert> is non-NULL the variable it points to is
29 If B<ca> is non-NULL and B<*ca> is NULL a new STACK will be allocated.
30 If B<ca> is non-NULL and B<*ca> is a valid STACK
31 then additional certificates are appended in the given order to B<*ca>.
33 The B<friendlyName> and B<localKeyID> attributes (if present) on each
34 certificate will be stored in the B<alias> and B<keyid> attributes of the
37 The parameter B<pass> is interpreted as a string in the UTF-8 encoding. If it
38 is not valid UTF-8, then it is assumed to be ISO8859-1 instead.
40 In particular, this means that passwords in the locale character set
41 (or code page on Windows) must potentially be converted to UTF-8 before
42 use. This may include passwords from local text files, or input from
43 the terminal or command line. Refer to the documentation of
44 L<UI_OpenSSL(3)>, for example.
48 PKCS12_parse() returns 1 for success and zero if an error occurred.
50 The error can be obtained from L<ERR_get_error(3)>
54 Only a single private key and corresponding certificate is returned by this
55 function. More complex PKCS#12 files with multiple private keys will only
56 return the first match.
58 Only B<friendlyName> and B<localKeyID> attributes are currently stored in
59 certificates. Other attributes are discarded.
61 Attributes currently cannot be stored in the private key B<EVP_PKEY> structure.
