NAME

key_decryptsession, key_encryptsession, key_setsecret, key_gendes, key_secretkey_is_set − interfaces to rpc keyserver daemon

SYNOPSIS

#include <rpc/rpc.h>

int key_decryptsession(char *remotename, des_block *deskey);

int key_encryptsession(char *remotename, des_block *deskey);

int key_gendes(des_block *deskey);

int key_setsecret(char *key);

int key_secretkey_is_set(void);

DESCRIPTION

The functions here are used within the RPC’s secure authentication mechanism (AUTH_DES). There should be no need for user programs to use this functions.

The function key_decryptsession() uses the (remote) server netname and takes the DES key for decrypting. It uses the public key of the server and the secret key associated with the effective UID of the calling process.

The function key_encryptsession() is the inverse of key_decryptsession(). It encrypts the DES keys with the public key of the server and the secret key associated with the effective UID of the calling process.

The function key_gendes() is used to ask the keyserver for a secure conversation key.

The function key_setsecret() is used to set the key for the effective UID of the calling process.

The function key_secretkey_is_set() can be used to determine whether a key has been set for the effective UID of the calling process.

RETURN VALUE

These functions return 1 on success and 0 on failure.

NOTES

Note that we talk about two types of encryption here. One is asymmetric using a public and secret key. The other is symmetric, the 64-bit DES.

These routines were part of the Linux/Doors-project, abandoned by now.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
