Opening an RSA File

The RSA file type is primarily associated with OpenSSL.

RSA	File extension: RSA
	File type:	public/private key

What is an RSA file?

RSA files mostly belong to OpenSSL by OpenSSL Project Authors. An RSA file is a certificate, a public key, or a private key generated using the Rivest-Shamir-Adleman (RSA) cryptography algorithm. It contains text which is used to encrypt, decrypt, or sign files and messages for various domains. Cryptography and communication tools like OpenSSL and OpenSSH can create, read, and authenticate RSA keys and certificates. OpenSSH mainly uses an RSA file to save its private and public keys. Most developers and tools assign PEM filename extension to keys generated with RSA algorithm.

How to open RSA files

You need a suitable software like OpenSSL from OpenSSL Project Authors to open an RSA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your RSA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RSA file directly in the browser:. Just drag the file onto this browser window and drop it.

RSA file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the RSA files:

The RSA file extension is very common and is mainly used by one program with a specific format. The file formats most commonly found in RSA files are:

85% of all RSA files store the data in the certificate file format. A digital certificate is a unique, digitally signed document which authoritatively identifies the identity of an individual or organization. Using public key cryptography, its authenticity can be verified to ensure that the software or website you are using is legitimate. If you open these files in a text editor, you will see only illegible characters. RSA files are between 950 bytes and 2 KB in size. The file type is old but is used even today. The file name CERT.RSA or BNDLTOOL.RSA is characteristic of these files. Files like these are about googplay, mozilla, android, androidk, androidd, mojangcs, gamesir and oracle.
1% of all RSA files are using the well-known KEY file format to store the data. A public or private key is used in Public-key cryptography to digitally sign or verify documents, software or websites, or to authentice a user. These files are text files and can therefore be read using a text editor. The file size is in the range of 450 bytes to 1 KB. The keywords BEGIN are typical for these files.

The remaining 14% of all RSA files are files with no common format, the following 4 formats exist: JSON and Cadena. The category is message, apkeasyt, facebook, gamemodp, testkey or ipubgm. Just click the "Choose your .rsa file to analyze" button on this page to find out what your RSA file is.

an rsa public/private key is a special file format by OpenSSL Project Authors and should only be edited and saved with the appropriate software.

How to solve problems with RSA files

Associate the RSA file extension with the correct application.
Update your software that should actually open public/private keys. Because only the current version supports the latest RSA file format. Search, therefore, e.g. on the OpenSSL Project Authors manufacturer website after an available OpenSSL update.
To make sure that your RSA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
