  24 .SH DESCRIPTION
  25 The functions here are used within the RPC's secure authentication
  26 mechanism (AUTH_DES).
  27 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.
  34 It uses the public key of the server and the
  35 secret key associated with the effective UID of the calling process.
  36
  37 The function
  38 .BR key_encryptsession ()
  39 is the inverse of
  40 .BR key_decryptsession ().
  41 It encrypts the DES keys with the public key of the server and
  42 the secret key associated  with the effective UID of the calling process.
  43
  44 The function
  45 .BR key_gendes ()
  46 is used to ask the keyserver for a secure conversation key.
  47
  48 The function
  49 .BR key_setsecret ()
  50 is used to set the key for the effective UID of the calling process.
  51
  52 The function
  53 .BR key_secretkey_is_set ()
  54 can be used to determine whether a key has been
  55 set for the effective UID of the calling process.
  56 .SH "RETURN VALUE"
  57 These functions return 1 on success and 0 on failure.
  58 .SH NOTES
  59 Note that we talk about two types of encryption here.
  60 One is asymmetric using a public and secret key.
  61 The other is symmetric, the
  62 64-bit DES.
  63 .PP
  64 These routines were part of the Linux/Doors-project, abandoned by now.
