I'm ok with asymmetric encryption as this will AFAIK be the only way to 
get rid of entering the password for every encryption. But as I 
mentioned I don't want to depend on a private key stored somewhere, but 
I'd like to use my password as the private key. I would need a keypair 
where the public key is some I-don't-care-ascii-bulk, but the private 
key is exactly my password.
