int gnutls_pkcs12_simple_parse( gnutls_pkcs12_t p12,
  const char * password,
  gnutls_x509_privkey_t * key,

gnutls_pkcs12_t p12

the PKCS12 blob.

const char * password

optional password used to decrypt PKCS12 blob, 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 blob (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_*


This function parses a PKCS12 blob in p12blob and extracts the private key, the corresponding certificate chain, and any additional certificates and a CRL.

The extra_certs_ret and extra_certs_len parameters are optional and both may be set to NULL. If either is non−NULL, then both must be set.

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

A PKCS12 file may contain many keys and/or certificates, and there is no way to identify which key/certificate pair you want. You should make sure the PKCS12 file only contain one key/certificate pair and/or one CRL.

It is believed that the limitations of this function are acceptable for common usage, and that any more flexibility would introduce complexity that would make it harder to use this functionality at all.

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.


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
