  Washingtonpost.com: Encryption Special Report
Encryption has become one of the hottest hi-tech issues on Capitol Hill, as Congress debates whether the government should step in and limit the strength of encryption products to maintain law enforcement's historical ability to eavesdrop electronically on anyone it wants.
Modern encryption is achieved with algorithms that use a "key" to encrypt and decrypt messages by turning text or other data into digital gibberish and then by restoring it to its original form.
In 1996, the Clinton relaxed its stand somewhat, declaring that encryption software would no longer be considered a munition, unless it was created specifically for military purposes, and allowing manufacturers to incorporate stronger encryption into their products as long as they committed to systems that allow the government to recover keys.

  Encryption - Wikipedia, the free encyclopedia
In the mid-1970s, strong encryption emerged from the sole preserve of secretive government agencies into the public domain, and is now employed in protecting widely-used systems, such as Internet e-commerce, mobile telephone networks and bank automatic teller machines.
Encryption can be used to ensure secrecy, but other techniques are still needed to make communications secure, particularly to verify the integrity and authenticity of a message; for example, a message authentication code (MAC) or digital signatures.
Encryption or software code obfuscation is also used in software copy protection against reverse engineering, unauthorized application analysis, cracks and software piracy used in different encryption or obfuscating software

 Introduction to Encryption
Encryption is said to occur when data is passed through a series of mathematical operations that generate an alternate form of that data; the sequence of these operations is called an algorithm.
Encryption can be very useful in protecting information that is being transmitted from one computer to another; however it does nothing to protect the integrity of the channels along which those messages travel.
Encryption can help provide a high level of security, but there are other pertinent factors that can help users decide if it is the best solution for their needs.

 Encryption   (Site not responding. Last check: 2007-10-22)
Encryption is an effective way of minimising the risks of using technology.
Encryption involves encoding data that is being transmitted via a computer network or disk so that only the sender and the recipient can read the data.
Another element of encryption is authentication - the process of verifying that a file or message has not been altered in route from the sender to the recipient.

 Encryption (open literature only)
Encryption is used to protect the confidentiality of information when it must reside or be transmitted through otherwise unsafe environments.
Encryption is also used for "digital signatures" to authenticate the origin of messages or data.
In addition to the characteristics of a particular encryption algorithm that are required to support a given use, the algorithm itself is generally integrated into a larger system that handles other aspects of the area to which encryption is being applied to ensure correct use and to minimize the visibility of the use of encryption.

 XML Encryption Syntax and Processing
In encryption, the decryptor has only the cipher data and the specified transforms are enumerated for the decryptor, in the order necessary to obtain the octets.
Simple stream encryption algorithms generate, based on the key, a stream of bytes which are XORed with the plain text data bytes to produce the cipher text on encryption and with the cipher text bytes to produce plain text on decryption.
In encryption chaining modes this data is the first to be encrypted and is consequently called the IV (initalization value or vector).

 Encryption
Encryption is the process of changing text so that it is no longer easy to read.
Almost all modern encryption methods rely on a key - a particular number or string of characters which are used to encrypt, decrypt, or both.
Not using encryption, however, means that any data in transit is as easy to read as the contents of a postcard, sent in regular mail.

 Data Encryption Techniques
One very important feature of a good encryption scheme is the ability to specify a 'key' or 'password' of some kind, and have the encryption method alter itself such that each 'key' or 'password' produces a different encrypted output, which requires a unique 'key' or 'password' to decrypt.
The encryption key, the 'public key', is significantly different from the decryption key, the 'private key', such that attempting to derive the private key from the public key involves many many hours of computing time, making it impractical at best.
Encryption schemes can be broken, but making them as hard as possible to break is the job of a good cipher designer.

 Shirky: The RIAA Succeeds Where the Cypherpunks Failed
The first broad attempt by the Government to deflect general adoption of encryption came 10 years ago, in the form of the Clipper Chip.
Note that the broadening adoption of encryption is not because users have become libertarians, but because they have become criminals; to a first approximation, every PC owner under the age of 35 is now a felon.
Because encryption is becoming something that must run in the background, there is now an incentive to make its adoption as easy and transparent to the user as possible.
