The hash used to sign the application must match that of the downloaded software. Otherwise, users should not download the software as this will result in a security warning.
Efficient security process
It is easy to integrate the code signing process oman cell phone number the software development process . There are APIs and web-based integration that make the job easier. It can help to avoid security warnings and protect the integrity of the software. As a result, the customer does not have to experience any installation failures.
The first step is to find out the price of the code signing certificate and pay for it. You need to get it from one of the reputed CAs. The CA will verify the identity of the organization by performing the necessary due diligence based on the documentation provided. Upon completion of the validation, the certificate is delivered.
The developer will create a one-way hash of the code and encrypt it with the private key. This private key is known only to the user.
The hash and certificate are included with the software. The end user must decrypt the hash with the public key that is present in the certificate.
A new hash will now be created for the software. Once the hash is compared and determined to be the same, the software can be confirmed to be secure.
After code signing, information such as company details and timestamp is provided. It will confirm the entity from where the software originated and that no unauthorized personnel have tampered with the code.
The certificate can be used for various types of software including utility software, applications, web applications, operating systems, etc.
You should also note that when you purchase a certificate, you also choose the validity period. The certificate will expire beyond that period. Therefore, you will not be able to use it to sign any new executable files.
You might be surprised to learn that signatures on existing code snippets will also become invalid unless you provide them with a timestamp. This is a piece of data that indicates when the code was signed. If the signature was done within the validity period, everything is fine.
