With these it helps When I asked this question, I assumed there is some kind of good habit or something similar. Since there is not one provided, I decided to use my own solution, a little similar to DarkSquirrel42's suggestion.
I created my own encoder and decoder. Actually, I used exactly the same trick I described in my original post.

Digital Signature/Code Signing Question

wish helps you You can indeed get a code signing digital certificate in your name as an individual without having a company, I've done exactly this myself using the heavily discounted Comodo certificates from the Tucows author site.
There's a great walkthrough of all the steps you'll need here. All you need are a domain that's registered in your name with your phone number and address corresponding with your actual details and an email address you can respond from @ that domain. They contacted me to verify I existed and wanted proof of address and phone number (a scanned telephone bill did the trick).

I wish did fix the issue. Code signing certificate must have proper flag set in ExtKeyUsage extension, i.e. this is a special kind of certificate. This company doesn't seem to offer such certificates.

I hope this helps . It depends on the digital signature format you are using.
A basic signature container (i. e. PKCS#1) includes only the signed hash. An advanced format can include the certficate itself too or a reference to the certificate.

it should still fix some issue
To prove no data tampering the user will use the Digital Signature which will be the hash of the certificate with the private key of the user.

wish helps you Because of the algorithms used to generate the keys (RSA is the typical one), the answer is essentially "impossible in any reasonable amount of time" assuming that the key is of a sufficient bit length. As long as the private key is not stolen or given away, you won't be able to decrypt it with just a public key and a message that was hashed with the private key.
As linked to in @Henk Holterman's answer, the RSA algorithm is built on the fact that the computations needed to decrypt the private key - prime factorization being one of them - are hard problems, which cannot be solved in any reasonable amount time (that we currently know of). In other words, the underlying problem (prime factorization) is an NP problem, meaning that it cannot be solved in polynomial time (cracking the private key) but it can be verified in polynomial time (decrypting using the public key).
