|
||||
*
|
||||
* (C) Copyright 1986, Dana L. Hoggatt
|
||||
* 1216, Beck Lane, Lafayette, IN
|
||||
*
|
||||
* When consulting directly with the author of this routine,
|
||||
* please refer to this routine as the "DLH-POLY-86-B CIPHER".
|
||||
*
|
||||
* This routine was written for Dan Lawrence, for use in V3.8 of
|
||||
* MicroEMACS, a public domain text/program editor.
|
||||
*
|
||||
* I kept the following goals in mind when preparing this function:
|
||||
*
|
||||
* 1. All printable characters were to be encrypted back
|
||||
* into the printable range, control characters and
|
||||
* high-bit characters were to remain unaffected. this
|
||||
* way, encrypted would still be just as cheap to
|
||||
* transmit down a 7-bit data path as they were before.
|
||||
*
|
||||
* 2. The encryption had to be portable. The encrypted
|
||||
* file from one computer should be able to be decrypted
|
||||
* on another computer.
|
||||
*
|
||||
* 3. The encryption had to be inexpensive, both in terms
|
||||
* of speed and space.
|
||||
*
|
||||
* 4. The system needed to be secure against all but the
|
||||
* most determined of attackers.
|
||||
*
|
||||
* For encryption of a block of data, one calls myencrypt passing
|
||||
* a pointer to the data block and its length. The data block is
|
||||
* encrypted in place, that is, the encrypted output overwrites
|
||||
* the input. Decryption is totally isomorphic, and is performed
|
||||
* in the same manner by the same routine.
|
||||
*
|
||||
* Before using this routine for encrypting data, you are expected
|
||||
* to specify an encryption key. This key is an arbitrary string,
|
||||
* to be supplied by the user. To set the key takes two calls to
|
||||
* myencrypt(). First, you call
|
||||
*
|
||||
* myencrypt(NULL, vector)
|
||||
*
|
||||
* This resets all internal control information. Typically (and
|
||||
* specifically in the case on MICRO-emacs) you would use a "vector"
|
||||
* of 0. Other values can be used to customize your editor to be
|
||||
* "incompatable" with the normally distributed version. For
|
||||
* this purpose, the best results will be obtained by avoiding
|
||||
* multiples of 95.
|
||||
*
|
||||
* Then, you "encrypt" your password by calling
|
||||
*
|
||||
* myencrypt(pass, strlen(pass))
|
||||
*
|
||||
* where "pass" is your password string. Myencrypt() will destroy
|
||||
* the original copy of the password (it becomes encrypted),
|
||||
* which is good. You do not want someone on a multiuser system
|
||||
* to peruse your memory space and bump into your password.
|
||||
* Still, it is a better idea to erase the password buffer to
|
||||
* defeat memory perusal by a more technical snooper.
|
||||
*
|
||||
* For the interest of cryptologists, at the heart of this
|
||||
* function is a Beaufort Cipher. The cipher alphabet is the
|
||||
* range of printable characters (' ' to '~'), all "control"
|
||||
* and "high-bit" characters are left unaltered.
|

*
|
||||
* The key is a variant autokey, derived from a wieghted sum
|
||||
* of all the previous clear text and cipher text. A counter
|
||||
* is used as salt to obiterate any simple cyclic behavior
|
||||
* from the clear text, and key feedback is used to assure
|
||||
* that the entire message is based on the original key,
|
||||
* preventing attacks on the last part of the message as if
|
||||
* it were a pure autokey system.
|
||||
*
|
||||
* Overall security of encrypted data depends upon three
|
||||
* factors: the fundamental cryptographic system must be
|
||||
* difficult to compromise; exhaustive searching of the key
|
||||
* space must be computationally expensive; keys and plaintext
|
||||
* must remain out of sight. This system satisfies this set
|
||||
* of conditions to within the degree desired for MicroEMACS.
|
||||
*
|
||||
* Though direct methods of attack (against systems such as
|
||||
* this) do exist, they are not well known and will consume
|
||||
* considerable amounts of computing time. An exhaustive
|
||||
* search requires over a billion investigations, on average.
|
||||
*
|
||||
* The choice, entry, storage, manipulation, alteration,
|
||||
* protection and security of the keys themselves are the
|
||||
* responsiblity of the user.
