23 | .SH DESCRIPTION |
| 24 | The functions here are used within the RPC's secure authentication | |
| c13182ef MK |
25 | mechanism (AUTH_DES). |
| 26 | There should be no need for user programs to | |
| fea681da MK |
27 | use this functions. |
| 28 | ||
| 29 | The function | |
| c13182ef MK |
30 | .BR key_decryptsession () |
| 31 | uses the (remote) server netname and takes the DES key | |
| 32 | for decrypting. | |
| 33 | It uses the public key of the server and the | |
| fea681da MK |
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 | |
| 0425de01 | 41 | the secret key associated with the effective UID of the calling process. |

42 | |
| 43 | The function | |
| c13182ef | 44 | .BR key_gendes () |
| fea681da MK |
45 | is used to ask the keyserver for a secure conversation key. |
| 46 | ||
| 47 | The function | |
| c13182ef MK |
48 | .BR key_setsecret () |
| 49 | is used to set the key for the effective UID of the calling process. | |
| fea681da MK |
50 | |
| 51 | The function | |
| 52 | .BR key_secretkey_is_set () | |
| 53 | can be used to determine whether a key has been | |
| c13182ef | 54 | set for the effective UID of the calling process. |
| 2b2581ee MK |
55 | .SH "RETURN VALUE" |
| 56 | These functions return 1 on success and 0 on failure. | |
| 19c98696 | 57 | .SH NOTES |
| c13182ef | 58 | Note that we talk about two types of encryption here. |
| 19c98696 | 59 | One is asymmetric using a public and secret key. |
| c13182ef | 60 | The other is symmetric, the |
| fea681da | 61 | 64-bit DES. |
