File extension .CSR
| Full Name | Developer | Category |

| Certificate Signing Request Format | N/A | Web Files |
The .CRS or Certificate Signing Request file extension is used for containing encryption key pairs that are used to create an digital signature. This type of cryptographic key is generally used to sign and authenticate data over the internet and authenticate that data in order to assure the receiver that the data originated from an intended source and has not been tampered with.
A CSR file contains key-pair values for public keys typically used in encryption algorithms such as RSA (if generated by an OpenSSL utility software) as well as other values such as unique distinguisher field, subject DN (distinguished name) field and public key value field. Furthermore, the contents of a CSR may also include distinguished name fields such as Common Name (CN), organization (O), city (L), state or province (S), country (C) and email (E).

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CSR) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CSR extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CSR file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CSR extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CSR extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CSR file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CSR file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CSR file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CSR file) will be extended to the maximum.
It is also good to check
- if the .CSR file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
