RSA File Extension

What is RSA file?

RSA filename suffix is mostly used for RSA Certificate Format files. RSA files are supported by software applications available for devices running Linux, Mac OS, Windows. RSA file format, along with 6033 other file formats, belongs to the Misc Files category. Users are advised to use OpenSSL software for managing RSA files, although 3 other programs can also handle this type of file.

Programs which support RSA file extension

Below you will find an index of software programs that can be used to open RSA files divided into 3 categories according to system platform supported. Files with RSA extension, just like any other file formats, can be found on any operating system. The files in question may be transferred to other devices, be it mobile or stationary, yet not all systems may be capable of properly handling such files.

How to open file with RSA extension?

Being unable to open files with RSA extension can be have various origins. What is important, all common issues related to files with RSA extension can be resolved by the users themselves. The process is quick and doesn’t involve an IT expert. We have prepared a listing of which will help you resolve your problems with RSA files.

Step 1. Get the OpenSSL

Problems with opening and working with RSA files are most probably having to do with no proper software compatible with RSA files being present on your machine. This one is an easy one. Select OpenSSL or one of the recommended programs (for example, Mozilla Firefox) and download it from appropriate source and install on your system. Above you will find a complete listing of programs that support RSA files, classified according to system platforms for which they are available. If you want to download OpenSSL installer in the most secured manner, we suggest you visit website and download from their official repositories.

Step 2. Check the version of OpenSSL and update if needed

If you already have OpenSSL installed on your systems and RSA files are still not opened properly, check if you have the latest version of the software. Software developers may implement support for more modern file formats in updated versions of their products. The reason that OpenSSL cannot handle files with RSA may be that the software is outdated. The latest version of OpenSSL should support all file formats that where compatible with older versions of the software.

Step 3. Assign OpenSSL to RSA files

If you have the latest version of OpenSSL installed and the problem persists, select it as the default program to be used to manage RSA on your device. The next step should pose no problems. The procedure is straightforward and largely system-independent

Selecting the first-choice application in Windows

• Choose the Open with entry from the file menu accessed by right-mouse clicking on the RSA file
• Next, select the Choose another app option and then using More apps open the list of available applications
• Finally select Look for another app on this PC, point to the folder where OpenSSL is installed, check the Always use this app to open RSA files box and conform your selection by clicking OK button

Selecting the first-choice application in Mac OS

• Right-click the RSA file and select Information
• Proceed to the Open with section. If its closed, click the title to access available options
• Select OpenSSL and click Change for all...
• If you followed the previous steps a message should appear: This change will be applied to all files with RSA extension. Next, click the Continue button to finalize the process.

Step 4. Check the RSA for errors

You closely followed the steps listed in points 1-3, but the problem is still present? You should check whether the file is a proper RSA file. Being unable to access the file can be related to various issues.

1. Check the RSA file for viruses or malware

Should it happed that the RSA is infected with a virus, this may be that cause that prevents you from accessing it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the scanner detected that the RSA file is unsafe, proceed as instructed by the antivirus program to neutralize the threat.

2. Verify that the RSA file’s structure is intact

If the RSA file was sent to you by someone else, ask this person to resend the file to you. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. It could happen the the download process of file with RSA extension was interrupted and the file data is defective. Download the file again from the same source.

3. Check if the user that you are logged as has administrative privileges.

Some files require elevated access rights to open them. Switch to an account that has required privileges and try opening the RSA Certificate Format file again.

4. Verify that your device fulfills the requirements to be able to open OpenSSL

If the system is under havy load, it may not be able to handle the program that you use to open files with RSA extension. In this case close the other applications.

5. Verify that your operating system and drivers are up to date

Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with RSA Certificate Format file. Outdated drivers or software may have caused the inability to use a peripheral device needed to handle RSA files.
