2. Inkjet cartridges supplied for 'free' with inkjet printers are rarely full

OEM ink cartridges supplied withrepparttar printer are designed only to provide enough ink for a few pages to get you 'started'. Fromrepparttar 105108 manufacturer's perspective this is a great selling technique, as free cartridges can often makerepparttar 105109 difference between a retailer closing a sale or losing it…and once you've gotrepparttar 105110 printerrepparttar 105111 manufacturer is going to make money out of you every time you order more OEM ink! Supplying ink cartridges that are not full shortensrepparttar 105112 timeframe over which consumers start ordering OEM ink cartridges too. This bringsrepparttar 105113 manufacturer into profit on each customer much more quickly than had they supplied full cartridges for free withrepparttar 105114 printer.

3. Consumers have a choice about which inkjet cartridges to buy

It's true! Contrary to popular belief consumers are not obliged to purchase expensive OEM ink cartridges fromrepparttar 105115 manufacturer. They can in fact opt to buy cheaper 'compatible' ink cartridges or remanufactured cartridges, often realizing savings on their ink purchase of between 50% and 75%!! All major inkjet cartridge brands are covered, including Apple, Canon, Hewlett Packard, Lexmark, Brother, Epson, IBM and Xerox. What's more they dorepparttar 105116 job just as well as OEM cartridges but at a much lower cost!

4. Compatible inkjet cartridges DO NOT automatically void a printer's warranty

Regardless of what you might have heard compatible inkjet cartridges WILL NOT automatically void your printer warranty. In fact, it is ILLEGAL for manufacturers inrepparttar 105117 United States

Overview of XML Encryption

Continued from page 1

Ifrepparttar recipient does not knowrepparttar 105106 decryption key in advance, thenrepparttar 105107 sender generates and sends it. The key can be protected in transit by encrypting method or key agreement.

Ifrepparttar 105108 plaintext data to encrypt is an XML element or content, you encode it using UTF-8 and perform any necessary transforms to it, otherwise, if it is an external resource, you simply consider it as an octet sequence. You then encryptrepparttar 105109 data, creating CipherValue, which you place in EncryptedData.

Care must be taken when signing content that may later be encrypted; clearly;repparttar 105110 content must be restored to exactlyrepparttar 105111 original plaintext form forrepparttar 105112 signature to validate properly. To restorerepparttar 105113 plaintext inrepparttar 105114 signed content, userepparttar 105115 decryption transform method for XML signature defined byrepparttar 105116 XML encrypt joint W3C and IETF working group.

This transform also allows specifications of XML fragments that were encrypted and then signed with rest ofrepparttar 105117 document and, therefore, are not decrypted to validaterepparttar 105118 signature. Often, encrypted fragments are removed fromrepparttar 105119 signed information by usingrepparttar 105120 XPATH transform inrepparttar 105121 reference element, sincerepparttar 105122 meaningful information isrepparttar 105123 plaintext.

We can signrepparttar 105124 plaintext version of an encrypted element by includingrepparttar 105125 appropriate reference element pointing to it. Whenrepparttar 105126 signed document is confidential and encrypted after being signed, you should also protect against surreptitious forwarding in whichrepparttar 105127 recipient forwardsrepparttar 105128 signed confidential document to a competitor, encrypted byrepparttar 105129 competitor public key, trying to make it look as ifrepparttar 105130 sender sentrepparttar 105131 confidential information. To prevent surreptitious forwarding,repparttar 105132 signer should appendrepparttar 105133 recipient identities torepparttar 105134 document being signed.
