Function Documentation

_dbus_sha_compute()

dbus_bool_t _dbus_sha_compute	(	const DBusString *	data,
		DBusString *	ascii_output
	)

Computes the ASCII hex-encoded shasum of the given data and appends it to the output string.

Parameters

data	input data to be hashed
ascii_output	string to append ASCII shasum to

Returns

FALSE if not enough memory

_dbus_sha_final()

dbus_bool_t _dbus_sha_final	(	DBusSHAContext *	context,
		DBusString *	results
	)

SHA finalization.

Ends an SHA message-digest operation, writing the the message digest and zeroing the context. The results are returned as a raw 20-byte digest, not as the ascii-hex-digits string form of the digest.

Parameters

context	the SHA context
results	string to append the 20-byte SHA digest to

Returns

FALSE if not enough memory to append the digest

_dbus_sha_init()

void _dbus_sha_init

(

DBusSHAContext *

context

)

Initializes the SHA context.

Parameters

context

an uninitialized context, typically on the stack.

_dbus_sha_update()

void _dbus_sha_update	(	DBusSHAContext *	context,
		const DBusString *	data
	)

Feeds more data into an existing shasum computation.

Parameters

context	the SHA context
data	the additional data to hash
