+
+Overview
+========
+
+This specification extends the address subscription feed with commands, to
+enable name servers to broadcast entry updates from hostname holders.
+Implemented in 0.9.26, originally proposed in proposal 112.
+
+
+Motivation
+==========
+
+Previously, the hosts.txt subscription servers just sent data in a hosts.txt
+format, which is as follows::
+
+    example.i2p=b64destination
+
+There are several problems with this:
+
+- Hostname holders cannot update the Destination associated with their hostnames
+  (in order to e.g. upgrade the signing key to a stronger type).
+- Hostname holders cannot relinquish their hostnames arbitrarily; they must give
+  the corresponding Destination private keys directly to the new holder.
+- There is no way to authenticate that a subdomain is controlled by the
+  corresponding base hostname; this is currently only enforced individually by
+  some name servers.
+
+
+Design
+======
+
+This specification adds a number of command lines to the hosts.txt format. With these
+commands, name servers can extend their services to provide a number of
+additional features. Clients that implement this specification will be able to listen
+for these features through the regular subscription process.
+
+All command lines must be signed by the corresponding Destination. This ensures
+that changes are only made at the request of the hostname holder.
+
+
+Security implications
+=====================
+
+This specification does not affect anonymity.
+
+There is an increase in the risk associated with losing control of a Destination
+key, as someone who obtains it can use these commands to make changes to any
+associated hostnames. But this is no more of a problem than the status quo,
+where someone who obtains a Destination can impersonate a hostname and
+(partially) take over its traffic. The increased risk is also balanced our by
+giving hostname holders the ability to change the Destination associated with a
+hostname, in the event that they believe the Destination has been compromised;
+this is impossible with the current system.
+
+
+Specification
+=============
+
+New line types
+--------------
+
+There are two new types of lines:
+
+1. Add and Change commands::
+
+     example.i2p=b64destination#!key1=val1#key2=val2 ...
+
+2. Remove commands::
+
+     #!key1=val1#key2=val2 ...
+
+Ordering
+````````
+A feed is not necessarily in-order or complete. For example, a change command
+may be on a line before an add command, or without an add command.
+
+Keys may be in any order. Duplicate keys are not allowed. All keys and values are case-sensitive.
+
+
+Common keys
+-----------
+
+Required in all commands:
+
+sig
+  B64 signature, using signing key from the destination
+
+References to a second hostname and/or destination:
+
+oldname
+  A second hostname (new or changed)
+olddest
+  A second b64 destination (new or changed)
+oldsig
+  A second b64 signature, using signing key from nolddest
+
+Other common keys:
+
+action
+  A command
+name
+  The hostname, only present if not preceded by example.i2p=b64dest
+dest
+  The b64 destination, only present if not preceded by example.i2p=b64dest
+date
+  In seconds since epoch
+expires
+  In seconds since epoch
+
+
+Commands
+--------
+
+All commands except the "Add" command must contain an "action=command"
+key/value.
+
+For compatibility with older clients, most commands are preceded by example.i2p=b64dest,
+as noted below. For changes, these are always the new values. Any old values
+are included in the key/value section.
+
+Listed keys are required. All commands may contain additional key/value items
+not defined here.

+
+
+Signatures
+----------
+
+All commands must contain a signature key/value "sig=b64signature" where the
+signature for the other data, using the destination signing key.
+
+For commands including an old and new destination, there must also be an
+oldsig=b64signature, and either oldname, olddest, or both.
+
+In an Add or Change command, the public key for verification is in the
+Destination to be added or changed.
+
+In some add or edit commands, there may be an additional destination referenced,
+for example when adding an alias, or changing a destination or host name. In
+that case, there must be a second signature included and both should be
+verified. The second signature is the "inner" signature and is signed and
+verified first (excluding the "outer" signature). The client should take any
+additional action necessary to verify and accept changes.
+
+oldsig is always the "inner" signature. Sign and verify without the 'oldsig' or
+'sig' keys present. sig is always the "outer" signature. Sign and verify with
+the 'oldsig' key present but not the 'sig' key.
+
+Input for signatures
+````````````````````
+To generate a byte stream to create or verify the signature, serialize as follows:
+
+- Remove the "sig" key
+- If verifying with oldsig, also remove the "oldsig" key
+- For Add or Change commands only,
+  output example.i2p=b64dest
+- If any keys remain, output "#!"
+- Sort the options by UTF-8 key, fail if duplicate keys
+- For each key/value, output key=value, followed by (if not the last key/value)
+  a '#'
+
+Notes
+
+- Do not output a newline
+- Output encoding is UTF-8
+- All destination and signature encoding is in Base 64 using the I2P alphabet
+- Keys and values are case-sensitive
+- Host names must be in lower-case
+
+
+Compatibility
+=============
+
+All new lines in the hosts.txt format are implemented using leading comment
+characters, so all older I2P versions will interpret the new commands as
+comments.
+
+When I2P routers update to the new specification, they will not re-interpret
+old comments, but will start listening to new commands in subsequent fetches of
+their subscription feeds. Thus it is important for name servers to persist
+command entries in some fashion, or enable etag support so that routers can
+fetch all past commands.
