      Parameters:
      priv - Stream used to write the destination and private keys
      pub - Stream used to write the destination (may be null)

    • genRandomKey

      public static void genRandomKey(OutputStream priv, OutputStream pub, SigType sigType)
      Generate a random destination key. Caller must close streams. Fails silently.
      Parameters:
      priv - Stream used to write the destination and private keys

    • checkPrivateDestination

      public static boolean checkPrivateDestination(String dest)
      Check whether a base64-encoded {dest,privkey,signingprivkey[,offlinesig]} is valid This only checks that the length is correct. It does not validate for pubkey/privkey match, or check the signatures.
      Parameters:
      dest - The base64-encoded destination and keys to be checked (same format as PrivateKeyFile)
      Returns:
      true if valid

    • getDest

      public static Destination getDest(String s) throws DataFormatException
      Resolve the destination from a key or a hostname
      Parameters:
      s - Hostname or key to be resolved
      Returns:
      the Destination for the specified hostname, non-null
      Throws:
      DataFormatException - on bad Base 64 or name not found

    • parseParams

      public static Properties parseParams(String args) throws SAMException
      Parse SAM parameters, and put them into a Propetries object Modified from EepGet. COMMAND and OPCODE are mapped to upper case; keys, values, and ping data are not. Double quotes around values are stripped. Possible input: 
        COMMAND
  COMMAND OPCODE
  COMMAND OPCODE [key=val]...
  COMMAND OPCODE [key=" val with spaces "]...
  PING
  PONG
  PING any   thing goes
  PONG any   thing   goes

  Escaping is allowed with a backslash, e.g. \"
  No spaces before or after '=' allowed
  Keys may not be quoted
  COMMAND, OPCODE, and keys may not have '=' or whitespace unless escaped
  Duplicate keys not allowed
      A key without a value is not allowed by the spec, but is returned with the value "true". COMMAND is returned as the value of the key ""COMMAND"". OPCODE, or the remainder of the PING/PONG line if any, is returned as the value of the key ""OPCODE"".
      Parameters:
      args - non-null
      Returns:
      non-null, may be empty. Does not throw on missing COMMAND or OPCODE; caller must check.
      Throws:
      SAMException - on some errors but not all
