What is a CRYPT1 file?
A CRYPT1 file is an encrypted database created by WhatsApp Messenger, an Android messenger application. It contains a 256-bit AES encrypted backup of downloaded sticker packs (stickers.db.crypt1), chat settings (chatsettingsbackup.db.crypt1), or your contacts' status rankings (statusranking.db.crypt1).
The .crypt1 extension is appended to a .DB file to create a .db.crypt1 file, which is used by WhatsApp to back up a user's stickers, chat settings, or contacts' status rankings. These files are similar to .CRYPT7, .CRYPT8, and .CRYPT12 files, which are encrypted database files that back up your WhatsApp message history.
If you are looking to decrypt a CRYPT1 database to view the settings or stickers it contains, you must first locate your WhatsApp key file, which stores the database's encryption key. The key file is stored in the following location: /data/data/com.whats.app/files/key. Note that, at this time, there is no known program that can decrypt a CRYPT1 database.
CRYPT1 files are located on the SD cards of Android devices with WhatsApp Messenger installed. You can find them in the following directory: /sdcard/WhatsApp/Backups.
NOTE: Only the Android version of WhatsApp Messenger creates CRYPT1 files. The iOS and desktop versions of WhatsApp messenger do not create CRYPT1 files.
Common CRYPT1 Filenames
stickers.db.crypt1 - An encrypted backup of the stickers you've sent and received through WhatsApp.
chatsettingsbackup.db.crypt1 - An encrypted backup of your WhatsApp chat settings.
statusranking.db.crypt1 - An encrypted backup of your WhatsApp contacts' status rankings.
How to open a CRYPT1 file
CRYPT1 files are typically not meant to be opened. If you ever need to migrate or restore your WhatsApp data, you can use your CRYPT1 files to restore your downloaded stickers, chat settings, and contacts' status ranking. To do so, ensure the stickers.db.crypt1, chatsettingsbackup.db.crypt1, and statusranking.db.crypt1 files are present within your Google Drive backup or SD card when you install and log in to WhatsApp.

UltraCrypter Ransomware Encrypted File
3.3 | 67 Votes
UltraCrypter is a type of malware utilized by cybercriminals that takes your files hostage and forces you to pay the perpetrator to unlock your files. It may be introduced to your computer through an executable file disguised as another type of file. This is typically done through malicious ads on compromised websites or email spam with attached files disguised as other files.
When the ransomware runs on your computer, it encrypts and renames standard files that are important to you with a .crypt1 extension. The files are typically documents, images, videos, and backup files, such as .PDF, .JPG, and .DB files. For example, an example.jpg file becomes example.jpg.crypt1. The virus changes the desktop wallpaper then generates a .HTML ransom note informing you of the takeover and what you need to do to recover your files, which is typically a payment via Bitcoin.
NOTE: CRYPT1 files became prevalent in May 2016 and are similar to encrypted .CRYPT files.
How to open a CRYPT1 file
No known program can restore CRYPT1 files to their original state. The best way to recover your files is to retrieve them from a recent backup or perform a System Restore to a point before your computer was infected.
FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
