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().

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 an function for each fo 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,

Parameters:

	context	a hx509 context.

	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.).

Returns:

Returns an hx509 error code. HX509_UNSUPPORTED_OPERATION if the certificate store doesn't support the store operation.
