  1. This is a very flexible cipher. It can be used as an encryption algorythim, as a random number generator, and a way to test randomness of a prng (I know that will make you cringe but please look at it before you come to an opinion). The sample was taken from a prng found here for medical purposes from this site(https://stattrek.com/statistics/random-number-generator.aspx#error)...see Excel sheet named prng histogram at the link or click here. http://hishouseinc.com/encryption.php Next video will be how to use this alg. as a prng.
  2. A video explaining decryption of the positional cipher With multiple passes the cipher text can equal any one of the numbers or letters of the key. Meaning the key length only needs to be as long as all letters or numbers used. Not as long as the plaintext.
  3. I'll explain in a minute: How this avoids frequency attacks. Language attacks. How to decode. Applied Diffie Helman for P.F.S Simple applied variations that make this secure.
  4. Decided to post this and explain my new cipher. Interested in hearing your opinioin. I can not figure out how to launch an attack.
  5. I have been working on this encryption alg. on and off for over six years. I call it the Chameleon cipher. Normally you create an account, the hashed salted password is stored and then the attackers build a database to try to guess your hash. Yes, I know there are many steps to last sentence. Here is an encryption I did on an md5 hash. Here is the way to use this. client enters their password - a hash is created. The hash is encrypted with a cipher text that changes randomly every time the user logs in. All this is done in the back ground even though they enter the same password. Once received the algorithm deciphers the cipher text into the md5 stored and gives permission for access. I know you are cringing at this point about "random" . This is a completely new cipher. Here is an encrypted md5 hash. The hash was not conditioned it was a 32 char hex. At first glance because of the high decimal numbers and the groupings of numbers is obviously less than 32, it is easy to think it is like a fairplay cipher. Sometime yes and sometimes no. The difficulty in decryption comes when you realize that 112 can mean any number or any letter, or combination of letters no matter how many times it is used or where it is located, AND this changes randomly. 112 58 61 220 207 188 25 53 110 176 221 58 234 195 19 17 63 78 232 62 242 136 The above is a common password taken from an md5 hash.
  6. This could easily be made into an impossible to decrypt cipher. Where one key of x and y organize the row into a single letter in the row randomly located and read that make up the plain text (modified book cipher)....this is more dangerous than i thought.
  7. Thank you, Decided to post this as a competition. I know it will never be succesfully attacked. I will be posting the details soon. In the mean time here is a fun encryption puzzle I made years ago using excell. You can find it here. It is free. scroll down to the bottom of the page: http://hishouseinc.com/inventions.php
  8. Hey James, this cipher is suddenly making me very nervous. I've studied ciphers for over 40 years. I see no way to decrypt it without the key. How do you handle the idea that someone someday will post a cipher that is solid, unbreakable, and they have just placed it in the publics hands. I'll post it, I'm not looking for drama just nervous.
  9. Thanks for the reply, i am ready the links to your reply. It is close to a threshold encryption but it does have major differences. Most encryption algorithms are not patented so i will post a video of the mapping. This surpasses my ability to code although it is a very simple process. The algorithm can be used in many ways. To discover sequences in arbitrary files, change the entropy of a random file, used as a one time pad. Once again i am new here and want to abide by all rules. If this can not be discussed here please delete this and let me know where i can move this topic.
  10. Just invented this. At the moment it is a pen and paper cipher. Does this have a practical application. One or more people want a document sealed/encrypted and only opened if all agree for it to be opened. Each encrypt it with their password and pass it on to the next. When all have it encrypted everyone gets a copy. Perhaps this already exists.
