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: should contain a gnutls_pkcs12_t structure
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 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

3.1.0
