 28 bba111bc 2021-03-28 op .Nm
 29 bba111bc 2021-03-28 op is an interactive browser for the Gemini protocol.
 30 bba111bc 2021-03-28 op It is able to process text/gemini and more in general every text/* file.
 31 bba111bc 2021-03-28 op .Nm
 32 bba111bc 2021-03-28 op also features tabs, bookmarks and out-of-band TOFU verification.

 48 bba111bc 2021-03-28 op .Nm
 49 bba111bc 2021-03-28 op aims to use the "Trust, but Verify (where appropriate)" approach.
 50 bba111bc 2021-03-28 op The idea is to define three level of verification for a certificate:
 51 bba111bc 2021-03-28 op .Bl -tag -width 12m
 52 bba111bc 2021-03-28 op .It untrusted
 53 bba111bc 2021-03-28 op the server fingerprint does NOT match the stored value
 54 bba111bc 2021-03-28 op .It trusted
 55 bba111bc 2021-03-28 op the server fingerprint matches the store one
 56 bba111bc 2021-03-28 op .It verified
 57 bba111bc 2021-03-28 op the fingerprint matches and has been verified out-of-band
 58 bba111bc 2021-03-28 op .El
 59 bba111bc 2021-03-28 op .Pp
 60 bba111bc 2021-03-28 op Most of the time the
 61 bba111bc 2021-03-28 op .Dq trusted
 62 bba111bc 2021-03-28 op level is enough, but where is appropriate users should be able to
 63 bba111bc 2021-03-28 op verify out-of-band the certificate.
 64 bba111bc 2021-03-28 op .Pp
 65 bba111bc 2021-03-28 op At the moment, there is no built-in support for an out-of-band
 66 bba111bc 2021-03-28 op verification though.
 67 bba111bc 2021-03-28 op .Pp
 68 bba111bc 2021-03-28 op Known certificates are store in
 69 bba111bc 2021-03-28 op .Pa ~/.telescope/known_hosts
 70 bba111bc 2021-03-28 op with a format similar to the
 71 bba111bc 2021-03-28 op .Xr ssh 1 Ns '
 72 bba111bc 2021-03-28 op .Pa known_hosts
 73 bba111bc 2021-03-28 op file.
 74 bba111bc 2021-03-28 op Each line is a record and it's made up by three fields, separated by a
 75 bba111bc 2021-03-28 op single space, according to the following format:
 76 bba111bc 2021-03-28 op .Dq HOST HASH TRUSTED
 77 bba111bc 2021-03-28 op where:
 78 bba111bc 2021-03-28 op .Bl -tag -width 12m
 79 bba111bc 2021-03-28 op .It HOST
 80 eb4388ee 2021-04-25 op the hostname, optionally followed by a colon (":") and a port number.
 81 bba111bc 2021-03-28 op .It HASH
 82 bba111bc 2021-03-28 op is the hash of the certificate, as outputted by
 83 6c04e8b6 2021-04-01 op .Xr tls_peer_cert_hash 3 .
 84 bba111bc 2021-03-28 op .It TRUSTED
 85 bba111bc 2021-03-28 op a single digit.
 86 bba111bc 2021-03-28 op 0 means trusted, 1 verified.

 88 bba111bc 2021-03-28 op .Sh DEFAULT KEY BINDINGS
 89 bba111bc 2021-03-28 op The default key bindings are very similar to GNU Emacs, but care has
 90 bba111bc 2021-03-28 op been taken to include also bindings familiar for
 91 bba111bc 2021-03-28 op .Xr vi 1
 92 bba111bc 2021-03-28 op and
 93 bba111bc 2021-03-28 op .Dq CUA
 94 bba111bc 2021-03-28 op users.
 95 bba111bc 2021-03-28 op In the following examples, C-x means Control-x, M-x means Meta-x,
 96 bba111bc 2021-03-28 op where the Meta key may be either a special key on the keyboard or the
 97 bba111bc 2021-03-28 op ALT key; otherwise ESC followed by the key X works as well, and C-M-x
 98 bba111bc 2021-03-28 op means to press the key X together with both Control and Meta.
 99 bba111bc 2021-03-28 op .Pp
100 bba111bc 2021-03-28 op Keys are usually a single character, like
101 bba111bc 2021-03-28 op .Sq p
102 bba111bc 2021-03-28 op or
103 bba111bc 2021-03-28 op .Sq n ,
