Before you can encrypt data on PDA, you must first define a container file that will be used to store the encrypted information in. This file is then "mounted" (or "connected") from SecuBox program. After "mounting" it appears in the Windows Mobile system as a new storage card and "looks and feels" like just another storage card to the user.

You can do anything with this virtual card you would do with a usual SD card - only that when you write data onto it, it is automatically encrypted. Whenever you read information from this storage card, it is automatically decrypted. The entire process is transparent to you.

You can create several virtual encrypted volumes using SecuBox, each of them will be seen as a separate PDA storage card. Up to encrypted 10 storage cards can be mounted at the same time. 

When you create an encrypted volume, SecuBox prompts you to select the name and properties of the container file, as well as the password that would protect this file from access. Then it generates a random 256-bit key, encrypts it and appends this encryption key to the file. This encryption key is used to encrypt and decrypt your information while reading from and writing to the SecuBox encrypted card.

It is the password you type in when creating the encrypted volume that protects access to the encrypted SecuBox volume. The encryption key itself is built from this password using SHA 512-bit algorithm (industry standard algorithm for strong key generation).

SecuBox provides Password Strength Meter which assists you in selecting your password. Password Strength Meter checks the password for complexity and against dictionaries. To decrease the chances of someone ever guessing your password,  select a hard-to-guess, or strong password. A strong encryption password must be as long as possible (never shorter than 8 characters), include mixed-case letters, include digits and punctuation marks, not be based on any personal information, not be based on any dictionary word, in any language. The Password Strength Meter will evaluate the quality of your password and will help you ensure your confidential information is properly protected.

Whenever you mount the storage on your Windows Mobile device, SecuBox encryption software asks you for your password. Once you enter the password, the secure storage is mounted and you are able to access the protected information on your PDA. Without your password, the encrypted data on your Windows Pocket PC looks like a jumble of meaningless characters and your data is completely inaccessible to any malicious user or anyone who wants to get access to your private data.

With SecuBox, your confidential information is transparently encrypted with the strongest algorithm acknowledged today - AES 256-bit. We intentionally do not offer you the multitude of algorithms to choose from for the following two reasons:

• all of them are weaker and less efficient and robust than AES 256-bit encryption algorithm;
• we do not want to put any additional burden on you with useless algorithm selection procedures - just INSTALL and GET SECURE.
