Encryption with Kremlin is easy to do and completely transparent.
For example: to encrypt a file, just right-click on the file and
choose Kremlin Encrypt.
After you enter your passphrase, it is hashed
with a 64-bit random salt using SHA1 (implemented as per the FIPS
180-1 standard) hash algorithm. This produces a 160 bit digest,
which is then used as the key to the encryption algorithm. If a
block encryption algorithm is selected,
encryption is performed in enhanced Cipher Block Chaining (CBC)
The encrypted kgb file can be transferred across the platforms!
For example you can encrypt the file on PC and then copy and decrypt
it on MAC.
Kremlin Decrypt allows you to decrypt the
files you have encrypted. To use it, just double-click on the encrypted
.kgb file. You should then enter your passphrase. It will appear
obscured with stars (optionally disabled) to prevent other people
from reading it off your screen.
By default, Kremlin decrypts all files in the .kgb archive. If
you would like to choose which files to decrypt, uncheck the Decrypt
All button and choose which files you would like to decrypt.
