24 | .SH DESCRIPTION |
| 25 | The functions here are used within the RPC's secure authentication | |
| c13182ef MK |
26 | mechanism (AUTH_DES). |
| 27 | There should be no need for user programs to | |
| fea681da MK |
28 | use this functions. |
| 29 | ||
| 30 | The function | |
| c13182ef MK |
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 | |
| fea681da MK |
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 | |
| c13182ef | 45 | .BR key_gendes () |
| fea681da MK |
46 | is used to ask the keyserver for a secure conversation key. |
| 47 | ||
| 48 | The function | |
| c13182ef MK |
49 | .BR key_setsecret () |
| 50 | is used to set the key for the effective UID of the calling process. | |
| fea681da MK |
51 | |
| 52 | The function | |
| 53 | .BR key_secretkey_is_set () | |
| 54 | can be used to determine whether a key has been | |
| c13182ef | 55 | set for the effective UID of the calling process. |
| fea681da | 56 | .SH NOTE |
| c13182ef MK |
57 | Note that we talk about two types of encryption here. |
| 58 | One is | |
| 59 | asymmetric using a public and secret key. | |
| 60 | The other is symmetric, the | |
| fea681da MK |
61 | 64-bit DES. |
| 62 | .br | |
| 63 | The routines were part of the linux/doors-project, abandoned by now. | |
| fea681da MK |
64 | .SH "RETURN VALUES" |
| 65 | The functions return 1 on success and 0 on failure. | |
