Matlab code of RC5 stream cipher encryption algorithm

Encrypt the text data using RC5 stream cipher encryption algorithm.

That does not sound like a question to me. That sounds like a homework assignment.

It was not very difficult to find source code for RC5, but as I cannot tell what the license is for the source, and as the source appears to include at least one algorithm that has patent restrictions, I am not comfortable posting the link. I am even less comfortable with the possibility that you are doing an assignment and intend to copy the code when your instructor probably intends that you write it yourself.

can anyone send rc5 encryption algorithm since rc5 algorithm is a part of my project.I need it can u send plz

[Walter Roberson]

If I understand correctly, the US patent for RC5 has expired since the time of my earlier post, but I do not have the resources to check for patents in other countries, which often last a bit later than in the USA since most people file in the USA first.

But even if I knew that the patent was clear world-wide, I would be concerned about the possibility that I was partaking in something that would be deemed plagerism.

Then too there is the problem that the source I found is a site that I frankly do not trust, and which requires payment to download the code.

Tell you what: You can do the search using your favorite search engine, and then the responsibility and risks will be all yours. And don't be surprised if the site gives you a trojan horse along with the code.

i searched everywhere sir,i didnt get the clue how to proceed

[Walter Roberson]

I checked again with google searches, and I still find downloadable code easily. You cannot have searched very hard at all.

pls can you send me the link sir

[swa gayu]

i found code in C but couldnt found in matlab sir.can you send me the link for implementing in matlab sir

Hint: the link to the code is not one of the first three responses.

sir i have already gone through this link,code available for only in C not in matlab.I need for matlab sir.can you help me plz

[Walter Roberson]

Using that link, I have no difficulty finding MATLAB source with MATLAB filenames ending in .m and with the manifest explicitly saying that the code is MATLAB code.

The appropriate link is within the first 100 hits that google returns for the search link I posted.

Sir, there are lot file with extension .m and what step do i have take?

thank you
