Is it legal to publish a secure communication channel algorithm that is personally developed and does not violate rights?

Question

Information Security

Hello.
The string of hashes encodes the login and password from my account on the toaster, from which I am writing, I boldly post it, because I am absolutely sure that it will never be hacked. I can turn this string back into an email/password pair with just an algorithm. Where I didn’t just wool, I didn’t find similar services anywhere, md5 doesn’t parse something back into text with the algorithm, no one yet.
This is not a direct analysis, but an indirect one. That is, in order to parse the hash back, you need to perform certain manipulations when assembling it. Then it will be possible to return. So all your tokens are safe, they are not in danger.
Can I publish a method on the network as a service that provides a secure communication channel or can I get it by header? What are the general options for the development of the algorithm? I just want everything to be legal, I prefer to sit at home at the computer to write code)

I want to open a service for storing passwords and other important crap, which will be turned into such lines as above. Assembled and disassembled with keys. If you don't know the key, the information is lost. I think it will be a useful service, is it possible to run this, that's the question. The results of hashing before dehashing can be stored anywhere, for example, at home on a computer, it is not necessary to write to the service database.
The problem is that you can encode a message with two YouTube video identifiers and send a couple of videos to someone in a personal message. It will not arouse any suspicion, but there has been a covert transmission of information at a distance that is incredibly difficult, if not impossible, to obtain. This is the point that worries me the most. I don't want accusations of complicity, but I can't let the algorithm die either.
I don’t want to patent anything and I won’t in any case, if there is at least one option not to do this.
Can I publish this algorithm on Habré tomorrow?

Answer 1

You have symmetric encryption with a key, and the hash function does not imply a reverse process. Second, until you mathematically prove the security of the cipher, you can hang the algorithm in a frame on the wall and hang beautiful noodles for blondes. And third, encryption is indeed licensed by the FSB.

The FSB license for cryptography is a document of the established form that provides a legal entity with a documentary opportunity to develop, produce, distribute encryption (cryptographic) means, information systems and telecommunication systems.

Answer 2

About licensing, look at the relevant regulation on licensing CIPF, everything is quite accessible there: www.consultant.ru/document/cons_doc_LAW_128739/1aa...
