The following dialog window appears when you run
Properties command for a
container file. If you select Re-encryption icon in the left
part of the dialog, it displays list of encryption options
for the container file you can change.
Encryption options you can change for container file include:
- Encryption algorithm
- Encryption mode
- Key generator
- Hash algorithm. KG-Ghost Key Generator supports several Secure Hash Algorithms.
If the container file is created with KG-Ghost Key Generator, you can change Hash algorithm
used for the container file.
If you change some encryption option for container file, it will cause a complete re-encrypting
all the data inside the container file. Please keep in mind the following precautions before
you change some encryption option and run the re-encryption process:
Re-encryption process may require a significant time, because BestCrypt will need
to overwrite whole container by re-encrypted data
When you change some option, you will need to enter new password for the container file.
It will be impossible to mount the container using old password.
If you have a backup copy of the key block (header) of the container, it will be impossible
to use the key block for the re-encrypted container. So it is strongly recommended to backup
the key block again when re-encryption process finishes.
- If you have Hidden Part inside the container, it will be lost. Re-encryption process
concerns original (outer) container. When the process runs, BestCrypt knows nothing about
any Hidden Parts inside the container. As a result, it will overwrite all the existing Hidden Parts.
