1. Java Security Architecture 1.1 Introduction to Java Security architectureJava provides classes and interfaces for the security framework. The JDK security API is the core API for the Java programming language, located in the Java.security package

The Java encryption and decryption technology series SHA Order Background Body Comparison of SHA-1 and MD5 Code implementation Conclusion OrderThe basic one-way encryption algorithm--MD5 is introduced in the

OrderThe basic one-way encryption algorithm--MD5 is introduced in the previous article, and the principle of its realization is also roughly stated. This article continues the one-way encryption mentioned earlier, mainly on Sha, like MD5, Sha is

L MD5 (Message Digest algorithm 5): a one-way hashing algorithm developed by RSA Data security Company. L SHA (Secure Hash algorithm): A 160-bit value can be generated for any length of data operation; SHA-1 In 1993, the Safe hashing algorithm (SHA)

OverviewBasic concepts of information security: BASE64 encoding Format MD5 (Message Digest algorithm 5, Information Digest algorithm) SHA (Secure Hash algorithm, security hashing algorithm) HMAC (Hash message authentication code,

Hash Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,

Secure Hash algorithm SHA (Secure hash Algorithm,sha)The idea of the algorithm is to receive a piece of plaintext, and then convert it into a paragraph (usually smaller) ciphertext in an irreversible way, or simply to take a string of input codes

Java comes with Data encryption class MessageDigest (MD5 or SHA encryption)DescriptionIn the website, in order to protect the website member's user name and the password and so on privacy information, therefore we in the user registers the direct MD5
