Beginning Cryptography with Java

Whereas cryptography can nonetheless be a debatable subject within the programming group, Java has weathered that typhoon and gives a wealthy set of APIs that let you, the developer, to successfully contain cryptography in applications-if you recognize how.

This ebook teaches you ways. Chapters one via 5 conceal the structure of the JCE and JCA, symmetric and uneven key encryption in Java, message authentication codes, and the way to create Java implementations with the API supplied via the Bouncy citadel ASN. 1 programs, all with lots of examples. development on that beginning, the second one 1/2 the ebook takes you into higher-level themes, permitting you to create and enforce safe Java purposes and utilize general protocols resembling CMS, SSL, and S/MIME.

What you'll research from this e-book how one can comprehend and use JCE, JCA, and the JSSE for encryption and authentication The ways that padding mechanisms paintings in ciphers and the way to identify and fasten standard error An realizing of ways authentication mechanisms are carried out in Java and why they're used tools for describing cryptographic items with ASN. 1 how you can create certificates revocation lists and use the web certificates prestige Protocol (OCSP) Real-world internet options utilizing Bouncy fort APIs

Who this ebook is for

This publication is for Java builders who are looking to use cryptography of their purposes or to appreciate how cryptography is getting used in Java purposes. wisdom of the Java language is important, yet you needn't be accustomed to any of the APIs discussed.

Wrox starting publications are crafted to make studying programming languages and applied sciences more uncomplicated than you think that, delivering a dependent, educational structure that may consultant you thru the entire thoughts concerned.

Example text

Adding two k-bit numbers requires k bit operations. We shall see that more complicated tasks can also be broken down into bit operations. The amount of time a computer takes to perform a task is essentially proportional to the number of bit operations. Of course, the constant of proportionality - the fraction of a nanosecond per bit operation depends on the particular computer system. ) When we speak of estimating the "time" it takes to accomplish something, we mean finding an estimate for the number of bit operations required.

Nor is the L('Y)-terminology useful for algorithms that are just slightly slower than polynomial time - such as the 0 ((ln n)c ln ln ln n ) primality test in [Adleman, Pomerance, and Rumely 1 983]. Some people prefer to give a different definition of "subexponential time". They use the term for an algorithm with running time bounded by a function of the form ef (k ) , where k is the input length and f(k) = o(k) (see Remark 6 of § 1 for the meaning of little-a). 2. Exercises for § 3 1 . (a) Using the big-0 notation, estimate in terms of a simple function of number of bit operations required to compute 3 n in binary.

II 1 1 1 1 000 + 00 1 1 1 1 0 1 00 1 0 1 1 0 Suppose that the numbers are both k bits long; i f one o f the two integers has fewer bits than the other, we fill in zeros to the left, as in this example, to make them have the same length. Although this example involves small integers (with k = 7), we should think of k as perhaps being very large, like 500 or 1000. Let us analyze in complete detail what this addition entails. Basically, we must repeat the following steps k times: 1. Look at the top and bottom bit and also at whether there's a carry above the top bit.
