How to extract text from your RSA file

  1. Click the "Select File" button above, and choose your RSA file.
  2. You’ll see a preview, if available.
  3. Click the "Convert file to..." button to extract text information.

Convert RSA to another file type

To convert your RSA file to another format, you need Android SDK or other Developer software.

About RSA files

The .RSA file extension is primarily associated with the Android application signing process. These files, often named CERT.RSA, reside within the META-INF directory of APK and JAR archives. They contain the binary, DER-encoded digital signature and public key certificate used to verify the integrity and authorship of the software. A secondary but significant use case involves generic RSA cryptographic keys used for SSH authentication or SSL/TLS handshakes.

Because .RSA files are binary encoded, they are strictly machine-readable. A common frustration for developers and security analysts is the inability to simply double-click and view the certificate's details (such as the issuer, fingerprint, or expiration date) in a standard text editor. Furthermore, these files are rigid; attempting to modify an .RSA file inside an application package will invalidate the digital signature, causing the app installation to fail or the operating system to reject the file entirely.

For inspection and debugging, the most practical solution is converting the .RSA file to a human-readable text format. Converting to TXT allows you to read the certificate details clearly. For compatibility with web servers or other security tools, converting to PEM (Privacy Enhanced Mail) or CER is the standard workflow.

Convert.Guru analyzes your RSA file, detects the exact format, and lets you read the text inside.

Users also converted SF, MF, ARSC, SO, ID_RSA, JSON, ZIP, PUB, RSP, TXT, 7Z, PEM and XML files.



The RSA Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RSA converter.
