FALSE if it outputs just bytes. (e.g. TRUE for cbc and ecb, and
FALSE for cfb and stream).
Parameters
-
mode -
One of the
MCRYPT_MODE_modenameconstants, or one of the following strings: "ecb", "cbc", "cfb", "ofb", "nofb" or "stream". -
lib_dir -
The optional
lib_dirparameter can contain the location where the algorithm module is on the system.
