TRUECRYPT
TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted drive. On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password or correct encryption key. Until decrypted, a TrueCrypt volume appears to be nothing more than a series of random numbers. The entire file system is encrypted (i.e., file names, folder names, contents of every file, and free space).
This software is highly recommended for securing data on laptops.
TrueCrypt performs the following tasks:
- Creates a virtual encrypted disk within a file and mounts it as a real disk.
- Encrypts an entire partition or storage device such as USB flash drive or hard drive.
- Encrypts a partition or drive where Windows is installed (pre-boot authentication).
- Encryption is automatic, real-time (on-the-fly) and transparent.
- Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).
- Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.
AxCrypt is used to share and work with stored documents, and e-mail attachments, in a secure manner.
If your documents reside on a document sharing service, intranet or file server AxCrypt is especially well suited and will usually seamlessly integrate, and make sharing and storing sensitive data as easy as not protecting it.
AxCrypt is great for protecting your documents such as private letters, correspondence, job information, medical information, financial details stored on a local hard disk or network server.
Just right-click any document file and encrypt it with AxCrypt. Viewing and opening for update is just as convenient as before encryption due to AxCrypt's automatic decryption/open/re-encryption function.
If you use a Key-File on a diskette or USB thumb drive, your files will be encrypted to the highest level of protection as long the Key-File is kept secret.
To encrypt a file, right-click it in Windows Explorer, select 'AxCrypt > Encrypt' and enter a pass phrase plus the path to an optional strong key file.
To edit or view an encrypted file - just double-click it.
