you can use the asymmetric variant: Generate a encryption key pair, store the
private key on your save place and the public key on your computer. Then you
can encrypt files without any password and decrypt them using your private key.
Dies this describe your purpose, except the fact you don't want an extra
private key? But think of the meaning of symmetric encryption: This meas, both
keys are the same and there is no difference between the private and public
key. So AFAIK you can't get around using an asymmetric key pair.
