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. |
