Installing a New Certificate with Certificate Wizard for Use in SSL/TLS

Creating a Self-Signed Certificate using OpenSSL for use with Microsoft Internet Information Services (IIS) 5

Create a certificate

To create a certificate, you first need to create a Certificate signing Request (CSR). Then you send the CSR to a certification authority which issues the certificate.

Use OpenSSL to generate a CSR
OpenSSL is installed with most GNU/Linux distributions. To download the source code or a Windows binary file, go to http://www.openssl.org/ and follow the installation instructions for your operating system. You can use OpenSSL to convert certificates and certificate signing requests from one format to another. For more information, see the OpenSSL man page or online documentation.

1.Open a command line interface terminal.
2.Type:
openssl genrsa -out privkey.pem 1024 to generate a private key file called privkey.pem in your current working directory.
3.Type:
openssl req -new -key privkey.pem -out request.csr

This command generates a CSR in the PEM format in your current working directory.
4.When you are prompted for the x509 Common Name attribute information, type your fully-qualified domain name (FQDN). Use other information as appropriate.
5.Follow the instructions from your certificate authority to send the CSR.
To create a temporary, self-signed certificate until the CA returns your signed certificate, type at the command line:
openssl x509 -req -days 30 -in request.csr -key privkey.pem -out sscert.cert

This command creates a certificate inside your current directory that expires in 30 days.

Peasant or binary multiplication

In base 2, long multiplication reduces to a nearly trivial operation. For each '1' bit in the multiplier, shift the multiplicand an appropriate amount and then sum the shifted values. Depending on computer processor architecture and choice of multiplier, it may be faster to code this algorithm using hardware bit shifts and adds rather than depend on multiplication instructions, when the multiplier is fixed and the number of adds required is small.

This algorithm is also known as Peasant multiplication, because it has been widely used among those who are unschooled and thus have not memorized the multiplication tables required by long multiplication. The algorithm was also in use in ancient Egypt.

On paper, write down in one column the numbers you get when you repeatedly halve the multiplier, ignoring the remainder; in a column beside it repeatedly double the multiplicand. Cross out each row in which the last digit of the first number is even, and add the remaining numbers in the second column to obtain the product.

The main advantages of this method are that it can be taught quickly, no memorization is required, and it can be performed using tokens such as poker chips if paper and pencil are not available. It does however take more steps than long multiplication so it can be unwieldy when large numbers are involved.

[edit] Examples
This example uses peasant multiplication to multiply 11 by 3 to arrive at a result of 33.

11 3
5 6
2 12
1 24
---
33
Describing the steps explicitly:

11 and 3 are written at the top
11 is halved (5.5) and 3 is doubled (6). The fractional portion is discarded (5.5 becomes 5).
5 is halved (2.5) and 6 is doubled (12). The fractional portion is discarded (2.5 becomes 2). The figure in the left column (2) is even, so the figure in the right column (12) is discarded.
2 is halved (1) and 12 is doubled (24).
All not-scratched-out values are summed: 3 + 6 + 24 = 33.
The method works because multiplication is distributive, so:

Dyma graff sy'n dangos yr arbediad nwy a gefais trwy newid fy hen fwyler nwy am un newydd.

O ystyried cyfartaledd y defnydd nwy yn y 3 blynedd cyn newid y bwyler (750 uned y flwyddyn), dyma'r defnydd nwy fel canran o 750 uned:

2005-2006 = 793 uned - 106%
2006-2007 = 688 uned - 92%
2007-2008 = 769 uned - 103%
2008-2009 = 429 uned - 57%
2009-2010 = 350 uned - 47%
2010-2011 = 320 uned - 43%[TARGED GAEAF YMA]

Heb ddefnyddio gwres canolog buaswn yn defnyddio < 100 uned y flwyddyn.
Felly mae tua 250 uned yn cael ei ddefnyddio i gynhesu'r ty yn y gaeaf.

THE PEOPLE in the US government are totally out of control, writes Doug Casey, chairman of Casey Research.

A poker player would say the government is "on tilt"...placing wild, desperate bets in the hope of getting rescued by good luck.

The things they're doing are not only unproductive, they're the exact opposite of what should be done. The country got into this mess by living beyond its means for more than a generation. That's the message from the debt that's burdening so many individuals; debt is proof that you're living above your means. The solution is for people to significantly reduce their standard of living for a while and start building capital. That's what saving is about, producing more than you consume.
