What you are describing is not even how RSA works.  You would be describing
symmetrical encryption, whereas RSA is asymmetrical.  There is no inherent
vulnerability with symmetrical encryption assuming you keep the key
private.  The idea behind RSA is that you can share your public key and
only the private key can decrypt that text, using a different key for
encryption and decryption is asymmetrical. For further reading refer to:
