RSA question

I would like to use a scheme that allows me to send out (encrpyted)
software licenses.
From what I understand after reading some articles on RSA, RSA
encryption can be used by anyone that has the public key to encrypt,
and only the person that has the private key can decrypt.
Is there a scheme that allows anybody to decrypt (based on the public
key), and only one person to encrypt (based on the private key)? Or is
this just semantics (e.g. reverse encryption/decryption, since it is
basically the same maths but with different numbers)?
.
