What is a .CRYPT1 file?
A .CRYPT1 file is a type of encrypted file used by WhatsApp Messenger, specifically on Android devices. This file contains important WhatsApp data such as sticker packs, chat settings, or contacts' status rankings, all of which are encrypted using 256-bit AES encryption for security. The file extensions you might see include stickers.db.crypt1 for sticker packs, chatsettingsbackup.db.crypt1 for chat settings, and statusranking.db.crypt1 for contacts' status rankings.
These .CRYPT1 files are part of WhatsApp's backup system, which helps in preserving user data. They are similar to other WhatsApp encrypted file formats like .CRYPT7, .CRYPT8, and .CRYPT12, which are used to back up message histories.
To open or access the contents of a .CRYPT1 file, you would typically need to decrypt it. The decryption key is stored in a key file located at /data/data/com.whats.app/files/key on the Android device. However, as of now, there are no publicly available tools that can decrypt .CRYPT1 files directly due to their strong encryption.
If you need to locate these files on your device, they are usually saved on the SD card in the /sdcard/WhatsApp/Backups directory. It's important to note that only the Android version of WhatsApp creates .CRYPT1 files; other versions like iOS and desktop do not use this file format.
In summary, .CRYPT1 files are encrypted backups created by WhatsApp on Android devices to secure various types of user data. While they ensure data security, accessing their contents outside of WhatsApp requires decryption, for which no tools are currently available.
