- !AMFCoder 1.30 (20-Jun-92)
- ===========================
- File Encoder
- ============
- AMFCoder is a program that will allow you to encrypt your files in a number
- of different ways,so that only after a similar decryption process may anyone
- make sense of their contents.
-
- Use
- ===
- Once loaded,drag the file to be encrypted onto the AMFCoder icon,opening a
- window.Set the encryption methods that you wish to code this file with
- (below),then click on OK to open a Save window.From the Save window,drag the
- save icon in the usual manner,to a filer window.The file will be encrypted,
- but performing the same process will decrypt the file again,so long as all
- the encryption methods are the same.
-
- Encryption Methods
- ==================
- 1) Bit Reverse
- This will reverse the bits in every byte in the file.Due to its nature,it
- must be used on its own,lest file corruption should occur.An error will be
- generated should you try to use this method with any other method.
-
- 2) Byte EORing
- This will exclusive-OR (EOR) every byte in the file with the byte given.This
- byte should be entered in the box provided,and should be between 0 and 255.
-
- 3) Word EORing
- This will exclusive-OR (EOR) every word in the file with the word given.This
- word should be entered in the box provided,and should be between 0 and
- FFFFFFFF (hexadecimal).
-
- 4) Text EORing
- This will exclusive-OR (EOR) the file with the text given.
-
- 5) Double text
- This will exclusive-OR (EOR) the file with both of the texts given,removing
- the problem that sometimes occurs with the Word EORing when there are many
- spaces,a problem that causes the password to be readable.
-
- AMFCoder needs to grab as much memory as the file you wish to encode is in
- size,so be sure that there is sufficient free memory to allow this to
- occur.
