[Gambas-user] How to decrypt a text? Any suggestions?

[Brant Wells]

Hans-Martin:

You could always come up with a quick formula based on the ASCII value 
of the Text that you are storing.   The upside is that you can always 
change it, etc.  However, the downside, is that it can be slow if your 
program has to call it many times.   An example...

Say that A=10, B=11, and C=12
 Step 1.  Reverse the string, from ABC to CBA (the ascii order would be 
121110
Step 2. Reverse the ASCII values so you'd wind up with 211101
   Note aboud step 2.  make sure you format ascii values that are less 
than 10 to have two digits: ID: 9  
   should be represented as 09


Step 3. Store the value from step 2 (in this case, 211101) into the 
password field... or convert the Values from step 2 back into their 
ascii Characters using the chr$() function.


The decryption routine should be just as easy to figure out. ;-)

See Ya!
