A payment ID may be encrypted using the tx secret key and the receiver's public view key. The receiver can decrypt it with the tx public key and the receiver's secret view key. Using integrated addresses now cause the payment IDs to be encrypted. Payment IDs used manually are not encrypted by default, but can be encrypted using the new 'encrypt_payment_id' field in the transfer and transfer_split RPC calls. It is not possible to use an encrypted payment ID by specifying a manual simplewallet transfer/transfer_new command, though this is just a limitation due to input parsing.
