What is a CRYPT1 file?

CRYPT1 files mostly belong to WhatsApp. CRYPT1 files are encrypted backup files used by WhatsApp that store your chat history in an SQLite database format.
This file is protected with encryption so that the contents remain secure. The data inside is unreadable without the proper decryption key, which is stored separately on your device.

Purpose: Securely record your chat and message data.

Structure: An encrypted SQLite database containing conversation details, metadata, and sometimes additional contact information.

Access: Requires the unique key from your device to decrypt and view the contents.

FilExt.com tip: If you want to view the data, you must first decrypt the file using the correct key, then open it with a SQLite viewer or a specialized tool. Always back up the original file before any decryption attempts.

How to open CRYPT1 files

You need a suitable software like WhatsApp to open a CRYPT1 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 CRYPT1 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CRYPT1 file directly in the browser:. Just drag the file onto this browser window and drop it.

CRYPT1 file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the CRYPT1 files:

The CRYPT1 file extension is used very often and is mainly used by one program with a specific format. The two most common formats are as follows:

• 95% of all CRYPT1 files start with the bytes 00 01 02, which are crucial for this file format. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The average file size is 960 bytes with most files being between 700 bytes and 49 KB in size. The file type was developed only in the last few years. The file name chatsettingsbackup.db.crypt1 or stickers.db.crypt1 is characteristic of these files. Such files sometimes refer to statusranking, commerce and backup.
• 4% of all CRYPT1 files have the same signature 00 01 01. These files contain neither text nor words, but only data. CRYPT1 files can be up to 500 KB in size, but are often around 870 bytes - 61 KB. An example of a file name is chatsettingsbackup.db.crypt1 or statusranking.db[1].crypt1.

All other CRYPT1 files (1%) have no consistent format. Just click the "Choose your .crypt1 file to analyze" button on this page to find out what your CRYPT1 file is.
