# gnutls\_pkcs12\_simple\_parse(3)

API function

## NAME

gnutls\_pkcs12\_simple\_parse - API function

## SYNOPSIS

**#include \<gnutls/pkcs12.h\>**

**int gnutls\_pkcs12\_simple\_parse(gnutls\_pkcs12\_t** *p12***, const char \*** *password***, gnutls\_x509\_privkey\_t \*** *key***, gnutls\_x509\_crt\_t \*\*** *chain***, unsigned int \*** *chain\_len***, gnutls\_x509\_crt\_t \*\*** *extra\_certs***, unsigned int \*** *extra\_certs\_len***, gnutls\_x509\_crl\_t \*** *crl***, unsigned int** *flags***);**

## ARGUMENTS

- gnutls\_pkcs12\_t p12

  A pkcs12 type

- const char \* password

  optional password used to decrypt the structure, bags and keys.

- gnutls\_x509\_privkey\_t \* key

  a structure to store the parsed private key.

- gnutls\_x509\_crt\_t \*\* chain

  the corresponding to key certificate chain (may be **NULL**)

- unsigned int \* chain\_len

  will be updated with the number of additional (may be **NULL**)

- gnutls\_x509\_crt\_t \*\* extra\_certs

  optional pointer to receive an array of additional certificates found in the PKCS12 structure (may be **NULL**).

- unsigned int \* extra\_certs\_len

  will be updated with the number of additional certs (may be **NULL**).

- gnutls\_x509\_crl\_t \* crl

  an optional structure to store the parsed CRL (may be **NULL**).

- unsigned int flags

  should be zero or one of GNUTLS\_PKCS12\_SP\_\*

## DESCRIPTION

This function parses a PKCS12 structure in  *pkcs12* and extracts the private key, the corresponding certificate chain, any additional certificates and a CRL. The structures in  *key* ,  *chain*  *crl* , and  *extra\_certs* must not be initialized.

The  *extra\_certs* and  *extra\_certs\_len* parameters are optional and both may be set to **NULL**. If either is non-**NULL**, then both must be set. The value for  *extra\_certs* is allocated using **gnutls\_malloc()**.

Encrypted PKCS12 bags and PKCS8 private keys are supported, but only with password based security and the same password for all operations.

Note that a PKCS12 structure may contain many keys and/or certificates, and there is no way to identify which key/certificate pair you want. For this reason this function is useful for PKCS12 files that contain  only one key/certificate pair and/or one CRL.

If the provided structure has encrypted fields but no password is provided then this function returns **GNUTLS\_E\_DECRYPTION\_FAILED**.

Note that normally the chain constructed does not include self signed certificates, to comply with TLS' requirements. If, however, the flag  **GNUTLS\_PKCS12\_SP\_INCLUDE\_SELF\_SIGNED** is specified then self signed certificates will be included in the chain.

Prior to using this function the PKCS **12** structure integrity must be verified using **gnutls\_pkcs12\_verify\_mac()**.

## RETURNS

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value.

## SINCE
