The machine readable response begins with an optional information
|
|
line:
|
|
|
|
info:<version>:<count>
|
|
|
|
<version> = this is the version of this protocol. Currently, this is
|
|
the number 1.
|
|
|
|
<count> = the number of keys returned in this response. Note this is
|
|
the number of keys, and not the number of lines returned.
|
|
It should match the number of "pub:" lines returned.
|
|
|
|
If this optional line is not included, or the version information is
|
|
not supplied, the version number is assumed to be 1.
|
|
|
|
The key listings are made up of several lines per key. The first line
|
|
is for the primary key:
|
|
|
|
pub:<fingerprint>:<algo>:<keylen>:<creationdate>:<expirationdate>:<flags>
|
|
|
|
<fingerprint> = this is either the fingerprint or the keyid of the
|
|
key. Either the 16-digit or 8-digit keyids are
|
|
acceptable, but obviously the fingerprint is best.
|
|
Since it is not possible to calculate the keyid from a
|
|
V3 key fingerprint, for V3 keys this should be either
|
|
the 16-digit or 8-digit keyid only.
|
|
|
|
<algo> = the algorithm number from RFC-2440. (i.e. 1==RSA, 17==DSA,
|
|
etc).
|
|
|
|
<keylen> = the key length (i.e. 1024, 2048, 4096, etc.)
|
|
|
|
<creationdate> = creation date of the key in standard RFC-2440 form
|
|
(i.e. number of seconds since 1/1/1970 UTC time)
|
|
|
|
<expirationdate> = expiration date of the key in standard RFC-2440
|
|
form (i.e. number of seconds since 1/1/1970 UTC time)
|
|
|
|
<flags> = letter codes to indicate details of the key, if any. Flags
|
|
may be in any order.
|
|
|
|
r == revoked
|
|
d == disabled
|
|
e == expired
|
|
|
|
Following the "pub" line are one or more "uid" lines to indicate user
|
|
IDs on the key:
|
|
|
|
uid:<escaped uid string>:<creationdate>:<expirationdate>:<flags>
|
|
|
|
<escaped uid string> == the user ID string, with HTTP %-escaping for
|
|
anything that isn't 7-bit safe as well as for
|
|
the ":" character. Any other characters may
|
|
be escaped, as desired.
|
|
|
|
creationdate, expirationdate, and flags mean the same here as before.
|
|
The information is taken from the self-sig, if any, and applies to the
|
|
user ID in question, and not to the key as a whole.
|
|
|
|
Details:
|
|
|
|
* All characters except for the <escaped uid string> are
|
|
case-insensitive.
|
|
|
|
* Obviously, on a keyserver without integrated crypto, many of the
|
|
items given here are not fully trustworthy until the key is
|
|
downloaded and signatures checked. For example, the information
|
|
that a key is flagged "r" for revoked should be treated as
|
|
untrustworthy information until the key is checked on the client
|
|
side.
|
|
|
|
* Empty fields are allowed. For example, a key with no expiration
|
|
date would have the <expirationdate> field empty. Also, a keyserver
|
|
that does not track a particular piece of information may leave that
|
|
field empty as well. I expect that the creation and expiration
|
|
dates for user IDs will be left empty in current keyservers. Colons
|
|
for empty fields on the end of each line may be left off, if
|
|
desired.
