At which point, all your effort in encrypting the transmitted data is lost!
Everything that the server displays in the browser is sent in plain text -
including the decrypted block!!
Unless the block is decrypted locally, it will be pointless encrypting it in
the first place! If you never encrypted it in the first place, the data would
still be sent once in clear text, just like in your system.
The second problem is that the PASSPHRASE is sent in clear text too, so now
the key is compromised too, or are you doing this over https:// ?

Umm, No. Sorry.
