Preface: A colleague consulted me about the implementation of Android DES Encryption, a simple implementation, today to sum up. Several other encryption methods:RSA encryption of Android data encryptionAES encryption of Android data encryptionDes encryption of Android data

Comments: Common encryption algorithms include symmetric encryption algorithms, asymmetric encryption algorithms, and Hash algorithms. Symmetric encryption is an encryption algorithm that uses the same key for encryption and decry

Http://www.cnblogs.com/1-2-3/archive/2007/09/17/colloquialism-digital-certificate-part1.htmlSummaryThis series is easy to read, so you can understand the basic principles of digital signatures and how to apply them (even if you are an enterprise boss who is not computer savvy, you can read this article). Then we step into the technical details, and finally will give a B/s information system using the digital signature demo.Because the digital signature is based on asymmetric

Objective: Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up. Several other encryption methods: RSA encryption of Android data encryptionAES encryption of Android data encryptionDes

This article all source code download:/files/chnking/encryptlongdata.rarI. Use of certificates combined with symmetric encryption algorithm to add and decrypt Long dataThe previous section discussed how to encrypt data using RSA certificates, which mentions: "The RSA implementation of dotnet has a characteristic that it must add some random numbers in the clear text, so the plaintext cannot fill 128 bytes, the actual test, the plaintext is up to 117 b

This article provides a detailed analysis of the pki encryption technology (openssl) in php. For more information, see The code is as follows: // Pki encryption// Openssl extension must be enabled for pki encryption.// Php. in

Introduction to Cryptographic algorithms I. Cryptography INTRODUCTION According to records, in 400 BC, the ancient Greeks invented the replacement code. 1881 the world's first telephone secrecy patent appeared. During the Second World War, the German military enabled the "Enigma" cipher Machine, which played a very important role in the war. With the development of information and digital society, People's awareness of the importance of security and confidentiality has been increasing, so in 19

Digital signatures are common: Before learning about digital signatures, you must first understand the SHA-1 digest and RSA encryption algorithm. Then, learn more about digital signatures.SHA-1 SHA-1 (secure hash algorithm) is Data encryption algorithm.The idea of this algorithm is to receive a piece of plain text, and then convert it into a section (usually smaller) ciphertext in an irreversible way, it ca

Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up. What is RSA encryption? RSA algorithm is the most popular public key cryptography algorithm, using the length can change the key. RSA is the first algorithm that can be used both for data encryption
