Function Documentation

  int hx509_certs_add (hx509_context context, hx509_certs certs, hx509_cert cert)
Add a certificate to the certificiate store.

The receiving keyset certs will either increase reference counter of the cert or make a deep copy, either way, the caller needs to free the cert itself.

Parameters
    context a hx509 context.
    certs certificate store to add the certificate to.
    cert certificate to add.

Returns
    Returns an hx509 error code.

  int hx509_certs_append (hx509_context context, hx509_certs to, hx509_lock lock, const char * name)
Same a hx509_certs_merge() but use a lock and name to describe the from source.

Parameters
    context a hx509 context.
    to the store to merge into.
    lock a lock that unlocks the certificates store, use NULL to select no password/certifictes/prompt lock (see Locking and unlocking certificates and encrypted data.).
    name name of the source store

Returns
    Returns an hx509 error code.

  int hx509_certs_end_seq (hx509_context context, hx509_certs certs, hx509_cursor cursor)
End the iteration over certificates.

Parameters
    context a hx509 context.
    certs certificate store to iterate over.
    cursor cursor that will keep track of progress, freed.

Returns
    Returns an hx509 error code.

  int hx509_certs_filter (hx509_context context, hx509_certs certs, const hx509_query * q, hx509_certs * result)
Filter certificate matching the query.

Parameters
    context a hx509 context.
    certs certificate store to search.
    q query allocated with hx509 query functions functions.
    result the filtered certificate store, caller must free with hx509_certs_free().

Returns
    Returns an hx509 error code.

Return HX509_CERT_NOT_FOUND if no certificate in certs matched the query.

  int hx509_certs_find (hx509_context context, hx509_certs certs, const hx509_query * q, hx509_cert * r)
Find a certificate matching the query.

Parameters
    context a hx509 context.
    certs certificate store to search.
    q query allocated with hx509 query functions functions.
    r return certificate (or NULL on error), should be freed with hx509_cert_free().

Returns
    Returns an hx509 error code.

Return HX509_CERT_NOT_FOUND if no certificate in certs matched the query.

  void hx509_certs_free (hx509_certs * certs)
Free a certificate store.

Parameters
    certs certificate store to free.

  int hx509_certs_info (hx509_context context, hx509_certs certs, int(*)(void *, const char *) func, void * ctx)
Print some info about the certificate store.

Parameters
    context a hx509 context.
    certs certificate store to print information about.
    func function that will get each line of the information, if NULL is used the data is printed on a FILE descriptor that should be passed in ctx, if ctx also is NULL, stdout is used.
    ctx parameter to func.

Returns
    Returns an hx509 error code.

  int hx509_certs_init (hx509_context context, const char * name, int flags, hx509_lock lock, hx509_certs * certs)
Open or creates a new hx509 certificate store.

Parameters
    context A hx509 context
    name name of the store, format is TYPE:type-specific-string, if NULL is used the MEMORY store is used.
    flags list of flags:

    •   HX509_CERTS_CREATE create a new keystore of the specific TYPE.

    •   HX509_CERTS_UNPROTECT_ALL fails if any private key failed to be extracted.

    lock a lock that unlocks the certificates store, use NULL to select no password/certifictes/prompt lock (see Locking and unlocking certificates and encrypted data.).
    certs return pointer, free with hx509_certs_free().

Returns
    Returns an hx509 error code.

  int hx509_certs_iter_f (hx509_context context, hx509_certs certs, int(*)(hx509_context, void *, hx509_cert) func, void * ctx)
Iterate over all certificates in a keystore and call a function for each of them.

Parameters
    context a hx509 context.
    certs certificate store to iterate over.
    func function to call for each certificate. The function should return non-zero to abort the iteration, that value is passed back to the caller of hx509_certs_iter_f().
    ctx context variable that will passed to the function.

Returns
    Returns an hx509 error code.

  int hx509_certs_merge (hx509_context context, hx509_certs to, hx509_certs from)
Merge a certificate store into another. The from store is keep intact.

Parameters
    context a hx509 context.
    to the store to merge into.
    from the store to copy the object from.

Returns
    Returns an hx509 error code.

  int hx509_certs_next_cert (hx509_context context, hx509_certs certs, hx509_cursor cursor, hx509_cert * cert)
Get next ceritificate from the certificate keystore pointed out by cursor.

Parameters
    context a hx509 context.
    certs certificate store to iterate over.
    cursor cursor that keeps track of progress.
    cert return certificate next in store, NULL if the store contains no more certificates. Free with hx509_cert_free().

Returns
    Returns an hx509 error code.

Start the integration

Parameters
    context a hx509 context.

Write the certificate store to stable storage.

Parameters
    context A hx509 context.
