Is it possible to create an 'always encrypted' standalone file?

I am looking for a solution where:

1. I can encrypt a file and it will stay encrypted on any computer even after the user enters the password.
2. The people I send it to will have the password to decrypt, but wouldn't need to have the same encryption software to open/decrypt the file. It would behave like an exe file where the receiver of the file wouldn't need the software that created it installed on their system.

For example:
The software encryptonclick will encrypt the file, but when the user enters the password, the file becomes decrypted allowing access by anybody.

The software axcrypt will encrypt the file and when you double-click the file and enter the password, the files opens. When you close the file, it is still encrypted, requiring the password each time the user wants to open the file. This is close to what I'm looking for EXCEPT... the problem is, the person who receives the file needs to have axcrypt installed in order to open/decrypt the file.

Is there an encryption solution which creates a self-contained encrypted, password protected file (software independent like an exe file) which remains encrypted after opening/decrypting?

Thanks for your help!
