The development of the internet world today increases the information system using online sites in an integrated manner. Business people use and develop the website as the main platform to reach customers worldwide. Even now, people assess prospective customer trust mainly by looking at the website. Several irresponsible parties widely use and develop this website platform to carry out data theft. This has made well-known browsers such as Chrome and Firefox issue website security standards, namely the use of SSL certificates. Or the transition of the website URL from HTTP and HTTPS.  An SSL certificate is a digital certificate that is installed on a website server and functions to secure the exchange of information and important data between the browser and the server. The SSL certificate will perform encryption by providing private data traffic to avoid hacking. Choosing an SSL certificate to be installed on a server and website must consider many aspects and be balanced with the needs of the website. In addition to considering the needs of the website, make sure you have considered the budget that will be spent. SSL Malaysia will provide tips for choosing the best SSL certificate for a website according to the needs of your website.   Determining the Number of Domains and Subdomains to be Secured The first tip you should pay attention to is the number of domains and subdomains you will secure. This will greatly affect the type of SSL certificate you will use and the budget you will spend. SSL Malaysia provides 3 types of SSL certificates based on the number of domains and subdomains you will secure, namely single domain, wildcard and multi domain. You can use a single domain if you only want to protect one domain or one subdomain of your website. For example, the domain sslMalaysia.com or the subdomain email.sslMalaysia.com You can use the wildcard certificate type if you want to protect one of your main domains along with all subdomains. An example of the main domain is sslMalaysia.com, using the wildcard certificate type you can also protect all subdomains of sslMalaysia.com such as email.sslMalaysia.com, blog.sslMalaysia.com and so on. Companies that have many subdomains but do not have a large budget to protect all of their subdomain sites widely use this type of certificate as a favorite. You can use Multi Domain if you have many domains or subdomains that you want to secure. Some certificates secure 3-5 domain slots and allow you to add slots by purchasing SAN.   Determining the Type of SSL Certificate Validation to Use The second tip to consider before purchasing an SSL certificate is the type of certificate validation that will be used. This type of validation will greatly affect the level of encryption of your data and information. SSL Malaysia provides 3 types of certificate validation, namely Domain Validation (DV), Organization validation (OV) and Extended Validation (EV). Each type of validation has its advantages. The lowest encryption of the three types of validation is DV and the highest is EV. Experts only recommend DV for use on blogs or personal websites that do not store sensitive email password data. If you use the website for online transaction processes and store sensitive data that requires a high level of encryption, you can choose the EV SSL certificate validation type.   Paying Attention to SSL Certificate Issuance Time The third tip you need to consider is the certificate issuance time. The issuance time of each certificate depends on the type of SSL certificate validation that you will use. The type of validation influences it. User feedback in the SSL certificate validation process also influences the issuance time.   Determining Additional Features If you have a website that conducts online transactions such as e-commerce, stores sensitive data such as banking. They have a larger budget for the level of security of your website. You can consider adding security features to your website. Several SSL certificate authority providers such as digicert and Symantec provide special additional features that perform daily malware scanning on your website. This will greatly help you to stay safe from attacks by irresponsible third parties.   SSL Certificate Price One of the most important considerations when you purchase an certificate is the price. Various factors influence the price of an SSL certificate.. Namely the type of SSL certificate based on the number of domains you want to secure. Also the type of validation and the amount of warranty offered. Those are 5 tips for choosing an SSL certificate wisely according to SSL Malaysia. Make sure you buy an certificate according to your budget and website needs. SSL Malaysia as a cheap SSL warehouse provides various types and brands of SSL certificates.

OpenSSL is a crucial tool for securing communications over networks. Learn how to check the OpenSSL version installed on your system using easy-to-follow steps. Step-by-Step Guide to Checking OpenSSL Version Follow these steps to determine the OpenSSL version on your operating system: Step 1: Open Terminal or Command Prompt First, open the terminal on your system. This applies to all operating systems, including Linux, macOS, and Windows. Step 2: Execute the OpenSSL Version Command To check the installed OpenSSL version, run the following command: openssl version The command will return output similar to this: OpenSSL 1.1.1k 25 Mar 2021 Here, 1.1.1k is the version number, and 25 Mar 2021 is the release date. The output shows the OpenSSL version designation and the date of its initial release: We can break down the version format to get valuable insight. Additionally, using flags helps structure the data. The sections below explain how to understand the version information in detail and how to use flags to format the data. Understanding the OpenSSL Version Format The version information format provides a lot of information. The position of the numbers represents the release type: Major Releases. You can recognize a major release if the first digit changes. This type of release can break compatibility with previous versions, for example, 2.0.0 vs. 3.0.0. Minor Releases. A minor release changes the second number of the version designation, e.g., 3.0.0 vs. 3.1.0. These releases are likely to contain new features; however, they should not break binary compatibility. You do not need to recompile applications to benefit from them. Patch Releases. A patch release changes the final number in the version, fe.g., 3.0.0 vs. 3.0.1. It only contains bug and security fixes, and the API and ABI remain compatible across patch releases. OpenSSL Version Command: Flags There are several flags that modify the openssl version command output. The -help flag lets you see an overview of all valid options for the openssl version command: openssl version -help The output shows the options that allow you to narrow down your search. The option that provides the most comprehensive set of information is: openssl version -a The -a flag compiles all the information contained under the individual flags into a single output: This option is convenient when troubleshooting or composing a bug report. The OPENSSLDIR line tells you where OpenSSL looks for its configurations and certificates. You can print that specific line by specifying the -d flag: openssl version -d In the example above, the configuration files and certificates are located at /usr/lib/ssl. If you specify the -c flag, the command provides CPU information that indicates which cryptographic operations or optimizations OpenSSL can take advantage of based on your CPU’s capabilities. For example: In the example above: 0xc2da2203478bffff represents a set of 64 bits, each corresponding to a specific CPU feature or capability. 0x842509 represents additional CPU features or optimizations specific to OpenSSL. OpenSSL uses this information to detect certain CPU capabilities that can be used to optimize cryptographic operations. Check OpenSSL Version on Different Operating Systems Depending on your operating system, the method to check the OpenSSL version might slightly vary. Below are commands specific to popular OS environments: 1. Ubuntu/Debian For Ubuntu or Debian-based systems, use: sudo apt list –installed | grep openssl This will list the installed OpenSSL version. 2. CentOS/RHEL On CentOS or RHEL, check with: rpm -q openssl This command queries the installed OpenSSL package. 3. macOS If you’re on macOS, especially with Homebrew, use: brew info openssl This will provide details about the OpenSSL installation. 4. Windows For Windows users, first, find the OpenSSL installation path: where openssl Navigate to the directory and run: openssl version Why Checking Your OpenSSL Version is Important Keeping your OpenSSL version up-to-date ensures compatibility with the latest security protocols and reduces vulnerabilities. Make sure to regularly check and update OpenSSL.
