4. Cryptainer LE: On-the-fly Encryption For Sensitive Data

Both private and business users often have data stored on their PCs that is considered to be sensitive. It may be lists with passwords, documents with internal company data, or perhaps access data for online banking.

Such data, as well as entire drives, can be encrypted with Cryptainer on-the-fly. In this connection, on-the-fly means that the data is saved in special pass phrase protected volumes while it is being created and encrypted at the same time.

Each volume can be loaded and unloaded. If a volume is initially closed, then the data is invisible. Only when the volume is loaded again, does the user have access to the data after entering a pass phrase. Up to four volumes can be opened simultaneously.

Cryptainer LE is based on a 128 bit implementation of the Blowfish algorithm. The maximum size of the encrypted volume is 20 MBytes. If you feel that 128 bit encryption is too unsafe or the volume size is insufficient, then for a fee ($30 to $90) you can upgrade to versions that work with a 448 bit key and allow larger volumes (up to 20 GB).

Moreover, the program also offers the possibility to encrypt mail attachments and consequently send them securely.

Cryptainer to go: Variation of Cryptainer for mobile use

The option of installing a mobile version of Cryptainer LE on an external drive makes the program especially interesting, particularly in connection with memory solutions like the EZ-Mini-USB. This is because it gives the user the ability to take all the functions that are offered by the programs installed locally on the computer with him in his shirt pocket and use them on other PCs when traveling.
