Code Signing SSL

The two certificates cannot be used because they do not have the same structure. Although both are digital certificates, they are validated differently. It has different advanced key usages listed in the certificate. Trying to use one for the other will cause various errors.

There is an important difference between code signing and SSL in the expiration date structure. If your website has an expired SSL certificate, you will be given warnings such as risky for your user. If an executable software is signed with a code signing certificate that is now invalid, no errors will be displayed as long as the code signing certificate is valid.

If you are comparing code signing certificates and SSL certificates, the main difference is as follows: SSL Certificates are for websites to enable HTTPS URLs. Code signing certificates are for applying digital signatures to software and code to avoid security warnings when installing software. Another important difference is that SSL / TLS encrypts all communication between clients and servers, but in the case of code signing, the software is not encrypted. Encrypts the signature and timestamp as part of the signature block. Integrity testing is done through hashing. Either way, the main difference between a code signing certificate and an SSL certificate is that SSL encrypts websites but the code signing certificate protects the software.

Until now, a standard UCC SSL certificate allows users to secure multiple domains and multiple hostnames with a single certificate on a single IP. Additional domains are listed as subject alternative names or SANs, while the base domain is registered as the common name. You can add or change SANs, but the generic name cannot be edited. There is an upper limit on the number of domains that can be included in a single certificate. This also depends on the CA (Certificate Authority) you choose.

It is the method of checking the authenticity of any software. Creates unique trace of data known as hash or hash. This allows comparisons. An algorithm-based method for a software that when executed generates a value known as checksum. It is used here to compare the software to check the originality of the software to check. If the values in the checksum do not match, you can tell that the program has been tampered with or modified.

It provides a digital print that is unique for a particular application. So it is used for security purposes. This process is irreversible. So essentially it only produces one-way switches. It always produces fixed size output.

Standard code signing certificates are available for individual entrepreneurs and legal entities. Verification by the certification authority may vary.

For Comodo:
- Your contact information is required (such as name, e-mail, phone, title).
- Verification will be made by phone number. For this, your company's phone number on infobel.com or kompass.com, its legal address and the phone number of the person to be contacted are required.

For Thawte / Symantec:
- Your contact information is required (such as name, e-mail, phone, title).
- Company registration at dnb.com/duns or a phone number is required to verify the phone number.

On the other hand, LeaderTelecom does not issue Code Signing certificates to individuals. Code Signing EV certificate can only be used by legal entities. The requirements for publication are the same, but the verification is more extensive due to the requirements of the EV (government sources are checked).

It is recommended for all publishers that generate and distribute code on the Internet or corporate networks. Users are often aware of the risks associated with downloading files from the internet. For this reason, signed files give much more confidence than unsigned applications. When users see the publisher's signature, they know it is not malicious software. Its browser or operating system does not give itself a risky warning. Here the publisher's signature makes the app reliable against any third party interference.

To sign a code, you must pass it through a special hash algorithm, then provide a digital signature using your private key to sign your hash value. Next, you create a signature block containing the digital signature and Code Signing certificate. Tools like Authenticode let you configure a timestamp for a signature block based on the current date and time. The last step is to link the signature block to your application with a timestamp. After these actions, you can publish a signed program for download on your website.
A timestamp is required to ensure that the certificate does not expire in its validity period. Thus, even if it expires, it will not become unreliable, which keeps the code valid. So if your application has a timestamp, the digital signature is valid even after the certificate expires. A new certificate is required only if you want to additionally sign your application. If you did not use the timestamping feature for signing at the time of application, you will need to re-sign the code and give it to your users.

After ordering, you receive a special email to get the certificate. When obtaining a certificate, use the same device and platform that you ordered. If you are using another computer or another web browser, you cannot upload the certificate. After downloading and installing it, your certificate will be moved to your browser's private certificate store. You can export it as a pfx file. You can then use this .pfx file to sign applications. There is one exception to this process. A certificate is created for Java. A client-side CSR code request is created in Java.

This type of certificate is issued for one and three years. This expires means you cannot create new signatures. All past signatures will run for a specific timestamp. Using timestamps with Microsoft Authenticode means the code will not expire when the certificate expires. The reason is the time stamp. So if timestamps are not used, you must re-sign the code when the certificate expires. Some certificates do not support the generation of timestamps. For example Netscape Object Signing and Sun Java.

As with the RFC 5280 specification, any code signing certificate can be used to sign Java code, AIR code, Authenticode, or VBS. From a technical point of view, there is no difference between code signing certificates. Some certificate authorities can impose certain restrictions on the scope of code signing certificates. As with Thawte and Symantec, there are restrictions where the certificate is broken down by type.

The folder is formed. These are known as obj and bin. For signing, the output files are mostly copied from the obj folder to the bin folder. If you sign files in the bin folder, then the files in the obj folder will be overwritten. If you sign the exe files located in the obj folder, your .msi application package will keep the signatures in the .exe files. Otherwise, the signatures will be lost. Because it is not overwritten.

There is no restriction. You can use the Code Signing certificate as long as you need, provided that the application is distributed by the organization to which the certificate is issued.

This is possible. The certificates have support for signing kernel mode code for both 32-bit and 64-bit versions of Windows® Vista and later, as well as Windows® Server 2008 and later versions.

It has a solution not for individuals but for legal entities. You need to use a code signing certificate in EV verification type. Programs signed with Code Signing EV are automatically trusted, even without the reputation of that publisher or file. To set a publisher reputation, a certificate must be issued only by a certification authority that is a member of the Windows Root Certificate program (such as Symantec).

Yes you can. Apple code signing certificates allow you to sign any Mac OS X software and updates. When you sign your code with an OS X Code Signing SSL, your users will know that the code came from a trusted source and has not been modified since you signed it.

This depends on the type of code signing certificate you have:
Extended Validation (EV) code signing certificates get an automatic SmartScreen reputation boost from Windows, so you won't get SmartScreen alerts after you renew EV code signing certificate. If you have a standard Organization Validation (OV) and Individual Validation (IV) type of validation certificate, you will likely need to go through the process of rebuilding the SmartScreen reputation of the renewed certificate before your application can be widely trusted on Windows systems. So it's a process, if you're not EV type, other types you depend on Microsoft's configuration.

It is possible to do this in a few steps in Windows. Type mmc in your Windows search feature and then click to launch the Microsoft Management Console application. Click Add / Remove Snap-in from the File menu. Click Certificates, then click Add. Select Computer account and then click Next. Select Local computer and then click Finish. Click OK.

EV code signing certificates allow you to sign codes using a private and public key system. When you request an EV (Extended Validation) code signing certificate, a public / private key pair is generated and the certificate authority issues a certificate containing the public key. In the EV verification type, transactions are a bit more serious. It takes some time to verify the information of legal entities.
