  25 .SH DESCRIPTION
  26 The functions here are used within the RPC's secure authentication
  27 mechanism (AUTH_DES). There should be no need for user programs to
  28 use this functions.
  29
  30 The function
  31 .BR  key_decryptsession ()
  32 uses the (remote) server netname and takes the DES key
  33 for decrypting. It uses the public key of the server and the
  34 secret key associated with the effective UID of the calling process.
  35
  36 The function
  37 .BR key_encryptsession ()
  38 is the inverse of
  39 .BR key_decryptsession ().
  40 It encrypts the DES keys with the public key of the server and
  41 the secret key associated  with the effective UID of the calling process.
  42
  43 The function
  44 .BR key_gendes ()
  45 is used to ask the keyserver for a secure conversation key.
  46
  47 The function
  48 .BR key_setsecret ()
  49 is used to set the key for the effective UID of the calling process.
  50
  51 The function
  52 .BR key_secretkey_is_set ()
  53 can be used to determine whether a key has been
  54 set for the effective UID of the calling process.
  55
  56 .SH NOTE
  57 Please note that we talk about two types of encryption here. One is
  58 asymmetric using a public and secret key. The other is symmetric, the
  59 64-bit DES.
  60 .br
  61 The routines were part of the linux/doors-project, abandoned by now.
  62
  63 .SH "RETURN VALUES"
  64 The functions return 1 on success and 0 on failure.
