Answer: Data encryption is the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign governments. It is also now used increasingly by the financial industry to protect money transfers, by merchants to protect credit-card information in electronic commerce, and by corporations to secure sensitive communications of proprietary information. Encryption systems are often grouped into families. Common families include symmetric systems (e.g. AES) and asymmetric systems (e.g. RSA), or may be grouped according to the central algorithm used (e.g. elliptic curve cryptography). As each of these is of a different level of cryptographic complexity, it is usual to have different key sizes for the same level of security, depending upon the algorithm used. For example, the security available with a 1024-bit key using asymmetric RSA is considered approximately equal in security to an 80-bit key in a symmetric algorithm (Source: RSA Security). The actual degree of security achieved over time varies, as more computational power and more powerful mathematical analytic methods become available. For this reason cryptologists tend to look at indicators that an algorithm or key length shows signs of potential vulnerability, to move to longer key sizes or more difficult algorithms. For example as of May 2007, a 1039 bit integer was factored, with the special number field sieve using 400 computers over 11 months. The factored number was of a special form; the special number field sieve cannot be used on RSA keys. The computation is roughly equivalent to breaking a 700 bit RSA key. However, this might be an advanced warning that 1024 bit RSA used in secure online commerce should be deprecated, since they may become breakable in the near future. Cryptography professor Arjen Lenstra observed that "Last time, it took nine years for us to generalize from a special to a non-special, hard-to-factor number" and when asked whether 1024-bit RSA keys are dead, said: "The answer to that question is an unqualified yes 64 bit encryption indicates that the size of the key used to encrypt the messageis 64 bits. The 64-bit encryption standard was used in some early internet and wireless communication encryption algorithms such as DES and WEP. Unfortunately, 64-bit encryption has proven too easy to decipher or crack in practice. Now, 128-bit encryption (in 3DES or TDES) have replaced the 64-bit encryption keys (DES).
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.

'64-bit ready' means the computer has the capabilities, maybe with or without modifications, to utilize a 64-bit processor, 64-bit operating system, 64-bit code, and more than 4GB of RAM.
Windows XP 32 bit will not run on a PC with a 64 bit processor. The two systems are incompatible and trying to install Windows XP 32 bit onto a computer with a 64 bit processor will result in errors.

64 bit OSes use special set of instructions as well as 64 bit memory space which is in principle is not supported by 32 bit processors.
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.

You need to choose stronger encryption and longer encryption key.
128 BIT-ENCRYPTION
128-bit
It depends on the encryption strength. For 64 bit connections, the key is 10 digits long. For 128 bit connections, the key is 26 digits long. For 256 bit connections, the key is 58 digits long.
It is possible to remove the 128-bit encryption in Facebook. This can be done by changing the file's proprieties in Window's Explorer.
Basic encryption (up to 256 bit encryption) software costs around $400 per year. Encryption softwares are not 100% foolproof.
You need a 64-bit computer with a working 64-bit operating system. When you install java it will install the 64-bit, it will recognize you have a 64-bit computer and install it
You can not "upgrade", you will have to reinstall. If your hardware meet 64-bit's requirement you can install 64-bit.
