-// This is modified RC4 decryption used for import of Toolbar autofill data
-// only. The difference from the Crypto Api implementation is twofold:
-// First, it uses a non-standard key size (160 bit), not supported by Microsoft
-// (it supports only 40 and 128 bit for RC4). Second, it codes 128 words with
-// value 0x0020 at the beginning of the code to enhance security.
-//
-// This class used in
-// components/autofill/browser/autofill_ie_toolbar_import_win.cc.
-//
-// This class should not be used anywhere else!!!
