  39 .
  40 The
  41 .B tripe-keys.master
  42 or
  43 .B tripe-keys.conf
  44 file is a simple line-based configuration file read by
  45 .BR tripe-keys (1).
  46 Lines may be empty (consist only of whitespace), be comments (first
  47 non-whitespace character is
  48 .RB ` # ')
  49 or have the form
  50 .IP
  51 .I name
  52 .RB [ = ]
  53 .I value
  54 .PP
  55 A
  56 .I name
  57 consists of alphanumeric characters and hyphens.  Values may contain
  58 substitutions, of the form
  59 .BI ${ name } \fR,
  60 which are replaced by the value assigned to
  61 .IR name .
  62 Many
  63 .IR name s
  64 have significance to the
  65 .B tripe-keys
  66 program: these are described below.  Many have sensible defaults.
  67 .SS "The tripe-keys.master file"
  68 The client configuration file is built by applying substitutions to the
  69 .B tripe-keys.master
  70 file.  The following tokens are substituted:
  71 .TP
  72 .B @MASTER-SEQUENCE@
  73 The sequence number of the most recently-added signing key.
  74 .TP
  75 .B @HK-MASTER@
  76 The fingerprint of the signing key identified by
  77 .BR @MASTER-SEQUENCE@ .
  78 .SS "Master repository parameters"
  79 .TP
  80 .I base-url
  81 The base URL of the key repository (usually with a trailing
  82 .RB ` / ').
  83 Typically, this will be something like
  84 .RB http://www.distorted.org.uk/vpn/ .
  85 No default.
  86 .TP
  87 .I repos-base
  88 The basename for the repository archive.  Default is

  90 .TP
  91 .I sig-base
  92 The basename template for repository signatures.  Default is
  93 .BR tripe-keys.sig-<SEQ> .
  94 The
  95 .RB ` <SEQ> '
  96 portion, if any, is replaced by the sequence number of the key which
  97 made the signature.
  98 .TP
  99 .I repos-url
 100 The URL for the key repository tarball.  Default is the concatenation of
 101 .I base-url
 102 and
 103 .IR repos-base .
 104 .TP
 105 .I sig-url
 106 The URL template for key repository signatures.  Default is the
 107 concatenation of
 108 .I base-url
 109 and
 110 .IR sig-base .
 111 .TP
 112 .I master-sequence
 113 The sequence number of the master authority's current signing key.  No
 114 default.  Usually set up automatically.
 115 .TP
 116 .I master-keygen-flags
 117 Additional options for generating master keys.  Default is
 118 .RB ` -l '.
 119 .TP
 120 .I master-attrs

 124 pairs separated by spaces.
 125 Default is empty.
 126 .TP
 127 .I hk-master
 128 The fingerprint of the current master signing key.  No default.  Usually
 129 set up automatically.
 130 .TP
 131 .I upload-hook
 132 A shell command to run by
 133 .B tripe-keys upload
 134 after it has successfully written the
 135 .I repos-file
 136 and
 137 .IR sig-file s.
 138 Default is
 139 .B ": run upload hook"
 140 which does nothing.
 141 .SS "Crypto parameters"
 142 .TP
