In my understanding of learning "Security", I'm looking to learn more about how RSA works. Here's my basic understanding of RSA:

• Having the public key allows you to encrypt things. Encrypting the same message "Hello" on two different computers using the same public key will produce the same resulting encrypted message

But if a person has access to the public key, couldn't someone just do a dictionary attack, encrypt all 5 letter words with the key until you find a matching encrypted message and then you know that it was "Hello" that was stored?

Basically...wouldn't be easier to brute force RSA encryption of passwords? Thanks!
