		<description><![CDATA[This week I needed to install OpenSSL 0.9.8g on one of my servers. When I went to configure and build the libraries with the Sun C compiler, I noticed that 64-bit libraries were produced by default. It turns out that this is the default behavior if you try to build OpenSSL on a 64-bit platform. [...]]]></description>

		<description><![CDATA[While checking my e-mail recently, I noticed that my inbox contained several new messages that were roughly 3MB in size. The quantity of messages was choking my poor text-based e-mail client, so I needed to figure out what has happening. After spending a few minutes reviewing my maillog, I noticed that my mail retrieval program [...]]]></description>

		<description><![CDATA[I use a variety of hardware in my day-to-day activities, and was curious to see how they compared to each other. While I could run a micro benchmarking tool to get detailed information on memory, cpu, network and disk throughput, I thought it would be easier to use openssl&#8217;s &#8216;speed&#8217; option to get a rough [...]]]></description>

		<description><![CDATA[Randomness is a key element in cryptography (seeds and shared secrets), TCP (ISNs), and can be useful when simulating client access patterns in test scripts. If an OS supports the /dev/random pseudo-device, the dd, od, and awk utiltiies can be used to generate random values: $ dd if=/dev/random count=1 2>/dev/null &#124; od -t u1 &#124; [...]]]></description>

		<description><![CDATA[I constantly find myself generating checksums, and for some reason each Operating System likes to implement their open message digest command ( if they provide one at all ). If your system is missing a digest command, you can use the openssl utility to generate one-time hashes. OpenSSL supports the SHA1, MD5 and RIPEMD160 algorithms, [...]]]></description>

		<description><![CDATA[I have an article titled debugging SSL in the December issue of SysAdmin magazine. The article covers techniques to debug SSL communications, and includes several useful examples. One of the examples shows how openssl can be used to check the operational status of a POP3s server. This is accomplished by feeding POP3 commands to openssl [...]]]></description>

		<description><![CDATA[I often find myself needing to protect sensitive data, and usually turn to OpenSSL for help. OpenSSL support a plethora of symmetric key encryption algorithms (AES, DES3, Blowfish, RC4), and comes with a variety of Operating Systems. To encrypt a file named private, we can pass one of the available symmetric key algorithms to OpenSSL: [...]]]></description>
