Today the topic of our review is “plugins”. What are these things, where they are used and why they are needed - the task that we must consider today.
For most users, this question remains behind the scenes. Until an urgent need arises, no one will specifically study the question of “how to install a plugin”, where to get it and how to use it for its intended purpose. Let's talk about everything in order.
1. What is a "plugin"? In short, this is an addition to the main program that can expand its functionality. For example, the Noise Ninja plugin for Photoshop is used to remove "noise" in digital photographs. If we draw an analogy with household appliances, these are which allow you to use the main device (vacuum cleaner) more fully and for a wider range of tasks. Cleaning an apartment, washing soft surfaces, disinfecting or removing heavy dirt in an apartment, kitchen, car or garage.
Many applications (programs) use the possibility of additional installation of plug-ins. This opportunity is provided by the software product developer for their own solutions or for third-party developers. Without going into technical details and details, we can say that with the help of plugins, you can expand the basic functionality of any program for your own needs.
Plugins can be paid or free. Install them or not - the user decides. With minimal knowledge (which plugins, where to get them and how to install them), you can achieve the desired result with minimal time and resources.
2. How to install the plugin? The answer to this question is best seen with an example. Let's take a look at how to install a Wordpress plugin.
Quick reference: Wordpress is a popular platform for implementing various web projects (website, blog, personal page). There are a huge number of plugins for this platform. They are built into the engine and serve either to speed up work, or to change the appearance, or to expand the functionality of the theme.
Before installing a plugin, you need to clearly understand why it is needed, how it will work and how necessary its installation is. A feature of plugins is a slight slowdown of the resource. In other words, the more plugins you install on your site, the longer it will take to load and the slower it will work.
The plugin can be installed directly from the admin panel, which has a search and installation function, or downloaded as an archive to your PC and then uploaded to the site directly from your hard drive. The installation procedure is extremely simple: find the plugin, click "install", after which it will appear in the list of installed plugins. In order to start using it, the installed add-on must be activated. That's the whole secret.
If you are not using the add-on, it is best to remove it. Some experts believe that plug-ins should be used only when they are completely indispensable. Which is better in your case - you can decide for yourself. The easiest way to check this is experimentally.
Another question that a large number of users want to hear the answer to: what is the purpose of and how to install the Windows Media Player plug-in. This plug-in is used in Internet browsers to display digital content (audio and video files) hosted on web pages on the Internet. For earlier versions of Windows, it was integrated into the system, for later versions it needs to be downloaded and installed as a separate file.
In order to check the presence of this plugin, for example, in Mozilla Firefox, you need to find the ADDITIONS item on the TOOLS tab (as an option, the key combination Ctrl / Shift / A). There you can see a list of installed add-ons. If Windows Media Player is not installed and you still need it, download it, save it to your PC, then run and install it. After installation, restart the "Fire Fox" and observe the installed add-on.
In conclusion, I would like to summarize briefly: today we looked at what a plugin is, how to install the plugin and how to prepare it for work. If you have any questions, Google will help you.

Error Information
1) CryptoPro window appearsCSP Insert Key Media
The appearance of this window means that you have not inserted the media with the private key for the certificate you selected.
You need to insert a key carrier. Make sure the OS "sees" it and try again.
If the previous steps did not help, you need to reinstall the certificate in the current user's Personal store with a binding to the private key. .
2) Failed to generate signature due to error: Unable to build certificate chain for trusted root authority. (0x800B010A)
This error occurs when the status of the certificate cannot be verified (no private key binding, no access to revocation lists or OCSP service), or root certificates are not installed.
Bind the certificate to the private key:
Check if the chain of trust is being built: open the certificate file (you can open it through Start-All Programs-CryptoPro-Certificates-Current User-Personal-Certificates), go to the Certification Path tab. If there are red crosses on this tab, or nothing at all except the current certificate (except if the certificate is self-signed)
Screenshots with examples of certificates that do not have a chain of trust.
To build a chain of trust, you need to download and install root and intermediate certificates. You can download them from the website of the CA that issued the certificate.
If you use a qualified certificate, then try to install these 2 certificates in the trusted root (these are the certificates of the Head CA of the Ministry of Telecom and Mass Communications and from them, if the Internet is available, a chain of trust should be built for any qualified certificate), if it does not help, then contact the CA that issued you the certificate .
To install the downloaded certificate to Trusted Root Certification Authorities, right-click on it - Select - Install Certificate - Current User - Place all certificates in the following store - Browse - Trusted Root Certification Authorities - Ok - Next - Finish - when the security warning appears about installing the certificate - click Yes-Ok. if you are installing an intermediate CA certificate, then select the repository - intermediate CAs.
Important: If you create CAdES-T or CAdES-XLongType 1, an error may occur if the TSP service operator certificate is not trusted, in which case you must install the root certificate of the CA that issued it in Trusted Root Certification Authorities.
3) If the signature is created but the certificate chain verification error is on, it means that there is no access to the lists of revoked certificates.
Lists of revoked certificates can be downloaded from the website of the CA that issued the certificate, after receiving the list it must be installed, the procedure is identical to the procedure for installing an intermediate CA certificate.
4) Error: 0x8007064A
The reason for the error is that the licenses for CryptoPro CSP and/or CryptoPro TSP Client 2.0 and/or CryptoPro OCSP Client 2.0 have expired.
To create a CAdES-BES signature, there must be a valid license for CryptoPro CSP
To create an XLT1, there must be valid licenses for the following software products: CryptoPro CSP, CryptoPro TSP Client 2.0, CryptoPro OCSP Client 2.0
You can view the status of licenses through: Start - All Programs - CRYPTO-PRO - Manage CryptoPro PKI licenses.
Solution: Purchase a license for the desired software product and activate it:
Start - All Programs - CRYPTO-PRO - CryptoPro PKI license management - select the desired software product - open the context menu (right-click) - select the All tasks item select the Enter serial number... - enter the license serial number - press the OK button
5) Keyset does not exist (0x80090016)
Error reason: The browser does not have enough rights to perform the operation - add our site to trusted
6) Access denied (0x80090010)
Error Cause: The private key has expired. Check the validity period Go to Start->All Programs(all applications)->CryptoPro->CryptoPro CSP. Go to the Service tab. Select the Test item, select a container with a private key, and in the test results you will be able to see its validity period. It is recommended to get a new key.
7) Mistake: Invalid algorithm specified. (0x80090008)
This error occurs if you are using a certificate whose algorithm is not supported by your crypto provider.
Example: You have CryptoPro CSP 3.9 installed and the certificate issued according to GOST 2012.
Or if a hash algorithm is used that does not match the certificate.
Also check the relevance of the CryptoPro CSP version.
