.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
PKCS12_parse - parse a PKCS#12 structure
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/pkcs12.h> \& int PKCS12_parse(PKCS12 *p12, const char *pass, EVP_PKEY **pkey, X509 **cert, STACK_OF(X509) **ca); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBPKCS12_parse() parses a \s-1PKCS12\s0 structure.

\fBp12 is the \s-1PKCS12\s0 structure to parse. pass is the passphrase to use. If successful the private key will be written to *pkey, the corresponding certificate to *cert and any additional certificates to *ca.

"NOTES"
Header "NOTES" Each of the parameters pkey, cert, and ca can be \s-1NULL\s0 in which case the private key, the corresponding certificate, or the additional certificates, respectively, will be discarded. If any of pkey and cert is non-NULL the variable it points to is initialized. If ca is non-NULL and *ca is \s-1NULL\s0 a new \s-1STACK\s0 will be allocated. If ca is non-NULL and *ca is a valid \s-1STACK\s0 then additional certificates are appended in the given order to *ca.

The friendlyName and localKeyID attributes (if present) on each certificate will be stored in the alias and keyid attributes of the \fBX509 structure.

The parameter pass is interpreted as a string in the \s-1UTF-8\s0 encoding. If it is not valid \s-1UTF-8,\s0 then it is assumed to be \s-1ISO8859-1\s0 instead.

In particular, this means that passwords in the locale character set (or code page on Windows) must potentially be converted to \s-1UTF-8\s0 before use. This may include passwords from local text files, or input from the terminal or command line. Refer to the documentation of \fBUI_OpenSSL\|(3), for example.

"RETURN VALUES"
Header "RETURN VALUES" \fBPKCS12_parse() returns 1 for success and zero if an error occurred.

The error can be obtained from ERR_get_error\|(3)

"BUGS"
Header "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 friendlyName and localKeyID attributes are currently stored in certificates. Other attributes are discarded.

Attributes currently cannot be stored in the private key \s-1EVP_PKEY\s0 structure.
