=pod =head1 NAME PKCS12_parse - parse a PKCS#12 structure =head1 SYNOPSIS #include <openssl/pkcs12.h> int PKCS12_parse(PKCS12 *p12, const char *pass, EVP_PKEY **pkey, X509 **cert, STACK_OF(X509) **ca); =head1 DESCRIPTION PKCS12_parse() parses a PKCS12 structure. B<p12> is the B<PKCS12> structure to parse. B<pass> is the passphrase to use. If successful the private key will be written to B<*pkey>, the corresponding certificate to B<*cert> and any additional certificates to B<*ca>. =head1 NOTES Each of the parameters B<pkey>, B<cert>, and B<ca> can be NULL in which case the private key, the corresponding certificate, or the additional certificates, respectively, will be discarded. If any of B<pkey> and B<cert> is non-NULL the variable it points to is initialized. If B<ca> is non-NULL and B<*ca> is NULL a new STACK will be allocated. If B<ca> is non-NULL and B<*ca> is a valid STACK then additional certificates are appended in the given order to B<*ca>. The B<friendlyName> and B<localKeyID> attributes (if present) on each certificate will be stored in the B<alias> and B<keyid> attributes of the B<X509> structure. The parameter B<pass> is interpreted as a string in the UTF-8 encoding. If it is not valid UTF-8, then it is assumed to be ISO8859-1 instead. In particular, this means that passwords in the locale character set (or code page on Windows) must potentially be converted to UTF-8 before use. This may include passwords from local text files, or input from the terminal or command line. Refer to the documentation of L<UI_OpenSSL(3)>, for example. =head1 RETURN VALUES PKCS12_parse() returns 1 for success and zero if an error occurred. The error can be obtained from L<ERR_get_error(3)> =head1 BUGS Only a single private key and corresponding certificate is returned by this function. More complex PKCS#12 files with multiple private keys will only return the first match. Only B<friendlyName> and B<localKeyID> attributes are currently stored in certificates. Other attributes are discarded. Attributes currently cannot be stored in the private key B<EVP_PKEY> structure. =head1 SEE ALSO L<d2i_PKCS12(3)>, L<passphrase-encoding(7)> =head1 COPYRIGHT Copyright 2002-2020 The OpenSSL Project Authors.
