I have a simple question.

Is it more weak to encrypt with the private key against the public key with RSA ?

Like is it easier to "crack", "brake", "solve", "decrypt" when I encrypt with the private key against the public key. Is it really the same process of encryption?

(In both cases we assume that the "breaker" doesn't know any of the keys)

**Edit:**

To be more precise, is there something that differs in the process of encryption with any of these two keys.

Is the only difference between the public and private is that the private can generate public keys but the public key can not generate private? If I want to encrypt with the private or the public key the result is the same, the encryption is passing by the same steps and then results in a difficult breakable encrypted output?
