Removable drive with data encryption

A Universal Serial Bus (USB) removable device for connection to a USB port of a computer with a non-transitory computer readable medium, the computer readable medium comprising:

• computer readable program code devices causing the computer to display a user interface on a monitor of the computer prompting a user for inputting a password, a selection of a data file on the computer, and a request for secure storage of the data file on the USB removable device;
• computer readable program code devices causing the computer to generate a encrypt/decrypt key from the password;
• computer readable program code devices causing the computer to encrypt the selected data file using the encrypt/decrypt key;
• computer readable program code devices configured to cause the computer to effect storing of the encrypted data file on the USB removable device;
• and
• computer readable program devices causing the computer to verify the input password including comparing the password with a stored key on the USB removable device,
• wherein memory of the computer device is free of a footprint of the encrypting of the selected data file.

A USB removable drive, comprising:

• memory storing encrypted private files and unencrypted public files;
• a random key generator operable by an operating system of a computer system linked to the USB removable drive to generate a key based on a user password;
• and
• a cryptography algorithm operable by the operating system to encrypt a user-selected one or more files for storing in the encrypted private files using the generated key and to decrypt the one or more of the encrypted private files identified in the request to decrypt, wherein the selected files are combined into a single file prior to the encrypting by the cryptography algorithm such that the selected files are encrypted and decrypted as a unitary file.
