E_deshash_ntlmssp()

bool E_deshash_ntlmssp	(	const char *	passwd,

Creates the DES forward-only Hash of the users password in DOS ASCII charset

Parameters

passwd	password in 'unix' charset.
p16	return password hashed with DES, caller allocated 16 byte buffer

Returns

False if password was > 14 characters, and therefore may be incorrect, otherwise True

Note

p16 is filled in regardless
