| | Encryption Keys: Basic Concepts |
 | | Secret keys are almost impossible to memorize (imagine that in order to encrypt some data you need to learn by heart the sequence of 255 numbers), and it takes several minutes to input them from the keyboard. | | | The required length of key for algorithms used in this program varies from 16 bytes (IDEA algorithm) to 255 bytes (RC-6 algorithm). | | | The necessity of storing encryption keys on a floppy disk or other removable medium is often considered as an inconvenience. |

| | >A Taxonomy for Key Escrow Encryption Systems |
| | With this proposal, a user's keys are generated jointly by the user and key escrow agents so the user cannot circumvent key escrow. | | | This component, which is operated by key escrow agents, manages the storage and release or use of data recovery keys. | | | This characterizes the liability of the escrow agents in case keys are compromised or become unavailable. |

| | Encryption (open literature only) |
| | 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. | | | Encryption is used to protect the confidentiality of information when it must reside or be transmitted through otherwise unsafe environments. | | | This however, is not so simple because of the differences in capabilities of public and private key encryption, key management, authentication issues, and the susceptibility of various algorithms to attack, all of which condition how a particular algorithm an be used. |

| | NetAction's Guide to Encryption (whole guide, no reviews) |
| | Encryption software programs use algorithms, or complex mathematical processes, to scramble and unscramble (or "encrypt" and "decrypt") the data. | | | For example, if the recipient's public key is available on a PGP server, your PGP software program can retrieve and store the key on your computer for use at any time. | | | An encryption algorithm scrambles data by combining the bits in the key with the data bits; in decryption, the algorithm unscrambles data by separating the data bits from the key bits. |

| | Encryption Technology |
| | Encryption is a procedure that involves a mathematical transformation of information into scrambled gobbledygook, called "cipher text." The computational process (an algorithm) uses a key--actually just a big number associated with a password or pass phrase--to compute or convert plain text into cipher text with numbers or strings of characters. | | | Key management is even more difficult when you would like to use your private keys from more than one computer. | | | For one thing, there are many different and incompatible encryption techniques available, and not all the software we need to use implements a common approach. |

| | With Key Manager you can see how many files are encrypted with any particular key, where these files reside, with which algorithm they are encrypted, etc. You can use Key Manager for convenient browsing encrypted files located anywhere on your computer. | | | The main reason for this is that frequent changing keys requires from users to manage the keys and keep track the information about which files have been encrypted with which key. | | | For more details see: Overview of Key Manager. |

| | The better-known encryption algorithms are fairly resistant to such attacks, and it should not be a problem if recognised standards are followed. | | | XML itself is the most popular technology for structuring data, and therefore XML-based encryption is the natural way to handle complex requirements for security in data interchange applications. | | | The requirement document must specify and describe the WG's choice with respect to the granularity of encryption, the data model and representation resulting from that choice, and the necessity and choice of canonicalization algorithms. |

| | The strength of any encryption scheme is based largely on the complexity of its algorithm -- the mathematical formula used to scramble the data -- and the length of the "key" required to encode and unscramble the information. | | | The network is organized hierarchically, according to each computer's processing power and function, with each segment of the network named with a decidedly equine theme. | | | Criminals can use the software to scramble evidence of their activities so thoroughly that even the most powerful supercomputers in the world would never be able to break into their codes. |

| | NodeWorks - Encyclopedia: Data Encryption Standard |
| | For DES, questions were raised about the adequacy of its key size early on, even before it was adopted as a standard, and it was the small key size, rather than theoretical cryptanalysis, which dictated a need for a replacement algorithm. | | | The key ostensibly consists of 64 bits; however, only 56 of these are actually used by the algorithm. | | | The complementation property means that the work factor for a brute force attack could be reduced by a factor of 2 (or a single bit) under a chosen-plaintext assumption. |

| | The creators of the new system say it could eventually generate cryptographic keys as strong as those used to keep files on desktop computers secure. | | | In a paper entitled Toward speech-generated cryptographic keys on resource constrained devices they write: "Rather than deriving the cryptographic key from merely the pass phrase that was spoken, we strive to generate a substantially stronger cryptographic key with entropy drawn both from the pass phrase spoken and how the user speaks it." | | | Turning a voiceprint into an encryption key requires significant computational effort. |
