Extract text from ChoicePoint encrypted files (CP9)

To convert other file formats to the "Encrypted Email Attachment" file type, you need software like CP Email Reporting Security or a similar tool.
A .cp9 file is an encrypted email attachment created by the discontinued CP Email Reporting Security software, developed by ChoicePoint. These files were historically used by HR professionals, insurance agents, and legal teams to securely transmit highly sensitive documents like background checks, risk assessments, and compliance reports over email.
The major disadvantage of the .CP9 format is its severe vendor lock-in. It is a proprietary, closed format that relies on discontinued legacy software to decrypt the payload. Because ChoicePoint was acquired by LexisNexis in 2008, the required decryption tools are no longer actively supported or easily available. This makes the files virtually impossible to open on modern systems, and the strict encryption prevents standard web browsers from reading the contents.
Ideally, users want to convert these encrypted archives into accessible formats like PDF, DOCX, or TXT. However, standard online converters will fail to process them because they cannot bypass the underlying encryption layer without the original password and software. While we cannot magically break military-grade encryption, our advanced analysis engine will inspect the file's binary structure, extract any available unencrypted metadata, and display underlying raw text strings to help you identify the file's origin.
Convert.Guru analyzes your CP9 file, detects the exact format, and lets you read the text inside.

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 CP9 converter.
