I was excited to hear about a PDF library not based on iText but alas, this is just ... If you're after an open source PDF library in Java, check out Apache PDFBox. Unlike the previous two protocols, the RSA scheme is an example of public-key cryptography: anybody can send a message to anybody else using publicly available information, rather like addresses or phone numbers Each person has a public key known to the whole world and a secret key known only to him- or herself When Alice wants to send message x to Bob, she encodes it using his public key He decrypts it using his secret key, to retrieve x Eve is welcome to see as many encrypted messages for Bob as she likes, but she will not be able to decode them, under certain simple assumptions The RSA scheme is based heavily upon number theory Think of messages from Alice to Bob as numbers modulo N ; messages larger than N can be broken into smaller pieces The encryption function will then be a bijection on {0, 1, , N 1}, and the decryption function will be its inverse What values of N are appropriate, and what bijection should be used Property Pick any two primes p and q and let N = pq For any e relatively prime to (p 1)(q 1): 1 The mapping x xe mod N is a bijection on {0, 1, , N 1} 2 Moreover, the inverse mapping is easily realized: let d be the inverse of e modulo (p 1)(q 1) Then for all x {0, , N 1}, (xe )d x mod N The rst property tells us that the mapping x x e mod N is a reasonable way to encode messages x; no information is lost So, if Bob publishes (N, e) as his public key, everyone else can use it to send him encrypted messages The second property then tells us how decryption can be achieved Bob should retain the value d as his secret key, with which he can decode all messages that come to him by simply raising them to the dth power modulo N Example Let N = 55 = 5 11 Choose encryption exponent e = 3, which satis es the condition gcd(e, (p 1)(q 1)) = gcd(3, 40) = 1 The decryption exponent is then d = 3 1 mod 40 = 27 Now for any message x mod 55, the encryption of x is y = x 3 mod 55, and the decryption of y is x = y 27 mod 55 So, for example, if x = 13, then y = 13 3 = 52 mod 55 and 13 = 5227 mod 55 Let s prove the assertion above and then examine the security of the scheme Proof If the mapping x xe mod N is invertible, it must be a bijection; hence statement 2 implies statement 1 To prove statement 2, we start by observing that e is invertible modulo (p 1)(q 1) because it is relatively prime to this number To see that (x e )d x mod N , we examine the exponent: since ed 1 mod (p 1)(q 1), we can write ed in the form 1 + k(p 1)(q 1) for some k Now we need to show that the difference xed x = x1+k(p 1)(q 1) x is always 0 modulo N The second form of the expression is convenient because it can be simpli ed using Fermat s little theorem It is divisible by p (since x p 1 1 mod p) and likewise 39. java convert word to pdf: How to convert DOCX files to PDF in Java - Gnostice edit pdf using itext in java Add and Edit MetaData PDF Document using iText in Java

The dynamic equations for the geodetic positions and position estimates are given by eqns (1141) and (1150), respectively These equations can be written as p = fp (p, v) p = fp ( , v) p (1164) (1165) Once we have identified the structure of the information, application of it to the chart would be similar to the following illustration Figure 19 RSA Bob chooses his public and secret keys He starts by picking two large (n-bit) random primes p and q where fp is the right-hand side of eqn (1141) By linearization of the Taylor series expansion of eqn (1164) around the solution of eqn (1165), we obtain p (1166) p = fp ( , v) + Fpp p + Fpv v + Fp where Fpp 0 0 0 0 0 0 0 His secret key is d, the inverse of e modulo (p 1)(q 1), computed using the extended Euclid algorithm Alice wishes to send message x to Bob 6: n v (RM +h)2 e v 2 (RN +h) cos( ) how to edit pdf in java Java and PDF - 06 - Editing (PdfStamper) - YouTube
