Thread Solved |
my prof told me to make my thesis system encrypt all that i save on it (on the add/save part of
a file maintenance) ... thats all he said,
ive seen something like this, but cnt remember...
can any1 help me on making a program that when ever i save a data to a database(using VB)
that data will be encrypt?? or some what be jumbled??
my only idea for this is using the ..... hmmm, changing the keydown sumthing of each letter i write when saving it to a database,
ex.
i try to save the word "MYNAME" on a database
then when i open the database
instead "MYNAME" is there
i will see sumthing like "SJWCNZ" (it changes the letter/or somewhat jumbled)
pls help me, i wanna learn how to make this,
thx a million for those who's willing to share

See this my encryption method, this a simple one. you can use this code to save the encryption result to database and read database with encryption reading.
Encrypt.zip
This is a screenshoot from my encryption.

asc = to get ascii.
mid = take a letter from taken value position and sum of value which it taken.
ex: mid("perfect",2,4) result = erfe
ReDim statement to serve as the initial declaration of a dynamic array. The array does not have to be declared anywhere else.
Asc(Mid(Label1.Caption, i + 1, 1)) - 77
get letter from label1 with mid function start from i+1 as many one letter and the result convert to ascii. then ascii be shift as 77.

you see the program have a reading encryption code. it working if label encryption changed. see the code when label encryption result change (label1 in program).
when you want to show data again after save, use the code to reading encryption after load data then show it to user.
Encrypt data in database -> load data -> encryption reading -> show data after encrypt to normal.
Ok. hope this helps.
all for the best friend.
NB : don't forget to mark this solved
