What is a .BIT file?

A .BIT file is a type of encrypted data file specifically created by a software program called FinalCrypt. This program is used for both encrypting (securing) and decrypting (unlocking) personal files to protect sensitive information. When a file, such as a photo (.JPG) or a video (.WMV), is encrypted using FinalCrypt, it is saved with the .BIT extension to indicate that it has been secured.

To open a .BIT file, you must use the FinalCrypt software. It is crucial to have the original key file that was used to encrypt the .BIT file. Without this key file, it is impossible to access or recover the data contained in the .BIT file. Therefore, it is very important to keep this key file in a secure location and to have backups of it.

One notable feature of .BIT files is that despite being encrypted, the first 70 bytes of the file contain a Message Authentication Code (MAC), which is visible in plain text. This MAC helps in verifying the integrity of the data and can exist in two versions: MAC_V1 or MAC_V2.

In summary, .BIT files are secure files created by FinalCrypt that can only be opened with the same program using a specific key file. Proper handling and storage of the key file are essential for accessing the encrypted data.
