    Demo Name: Main Author: Ted Rybicki Purpose: Sync up systems and workstations clock through firewalls with socks support. NOTE: You will need to set Name field in IdSocksInfo1 to your socks server for socks support to work correctly. History: Date: 27/10/2002 01:49:13 Checked with Indy version: 9.0 ---------------------------------------------------------------------------- Notes: Demonstrates a DateTime client getting current date and time from remote DateTimeServer A list of time servers is available at: http://www.eecis.udel.edu/~mills/ntp/servers.html

  • RSA算法是第一個(gè)能同時(shí)用于加密和數(shù)字簽名的算法

    RSA算法是第一個(gè)能同時(shí)用于加密和數(shù)字簽名的算法,也易于理解和操作。 RSA是被研究得最廣泛的公鑰算法,從提出到現(xiàn)在已近二十年,經(jīng)歷了各種攻擊的考驗(yàn),逐漸為人們接受,普遍認(rèn)為是目前最優(yōu)秀的公鑰方案之一。RSA的安全性依賴于大數(shù)的因子分解,但并沒(méi)有從理論上證明破譯RSA的難度與大數(shù)分解難度等價(jià)。即RSA的重大缺陷是無(wú)法從理論上把握它的保密性能如何,而且密碼學(xué)界多數(shù)人士?jī)A向于因子分解不是NPC問(wèn)題。RSA的缺點(diǎn)主要有:A)產(chǎn)生密鑰很麻煩,受到素?cái)?shù)產(chǎn)生技術(shù)的限制,因而難以做到一次一密。B)分組長(zhǎng)度太大,為保證安全性,n 至少也要 600 bits以上,使運(yùn)算代價(jià)很高,尤其是速度較慢,較對(duì)稱密碼算法慢幾個(gè)數(shù)量級(jí);且隨著大數(shù)分解技術(shù)的發(fā)展,這個(gè)長(zhǎng)度還在增加,不利于數(shù)據(jù)格式的標(biāo)準(zhǔn)化。目前,SET(Secure Electronic Transaction)協(xié)議中要求CA采用2048比特長(zhǎng)的密鑰,其他實(shí)體使用1024比特的密鑰。   這種算法1978年就出現(xiàn)了,它是第一個(gè)既能用于數(shù)據(jù)加密也能用于數(shù)字簽名的算法。它易于理解和操作,也很流行。算法的名字以發(fā)明者的名字命名:Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理論上的證明。

    JavaServer Faces (JSF) is the “offcial” component-based view technology in the Java EE web tier. JSF includes a set of predefned UI components, an event-driven programming model, and the ability to add third-party components. JSF is designed to be extensible, easy to use, and toolable. This refcard describes the JSF development process, standard JSF tags, the JSF expression language, and the faces-confg.xml confguration fle.

    Eclipse is the leading Integrated Development Environment (IDE) for Java, with a rich ecosystem of plug-ins and an open source framework that supports other languages and projects. You’ll fnd this reference card useful for getting started with Eclipse and exploring the breadth of its features. We rundown the Eclipse distributions and confguration options, then guide you through Views, Editors, and Perspec- tives in Workbench 101. We list the top shortcuts and toolbar actions for everyday development. And, we provide a guide to the best places for fnding plug-ins and getting involved with the Eclipse community.

    Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.

  • Run following Matlab commands to make sure the installation worked correctly. Unlike query function

    Run following Matlab commands to make sure the installation worked correctly. Unlike query function, filterdb does not load all waveforms to memory but returns filtered database object. This is useful when the resulting set of the query is too big to fit in memory. Consequent calls to read function can be made to read content of this filtered database object.

    This m file hide an image jpeg,png in another jpeg,png image. The height and width of the secret image is in LSB of 1st 32 pixels of 1st row of the cover image.This helps in the recovery of secret image. The secret image must be smaller than cover image.A message box will appear with a number ,that number is the maximum product of width and height of secret image that can be successfully embedded in the cover image. The final png image will appear in workspace with random name.This image contains the secret image.One such png image is in the zip file with name 4447.png it contains an image of res 100x122.
