Objective: For the SHA Safe hashing algorithm, before how to use, just stay in the heard of the stage, today in the picture Caching framework Glide source code found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption

Objective:For the SHA Secure Hash algorithm, not used before, just stay in the heard of the stage, today in the picture cache frame Glide source found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption algorithm, this just

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

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

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

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,

To put it bluntly, here we mainly describe some encryption and decryption algorithms implemented by Java, and finally introduce digital certificates. For example, the basic one-way encryption algorithm: Base64 strictly speaking, it belongs to the

From: http://snowolf.iteye.com/blog/379860 Encryption and decryption were once an important component of my graduation project. After many years of work, it was too simple to recall the encryption and decryption algorithm at that time.To put it

Exploring the principle and programming implementation of the SHA-1 algorithm in Redis source codeGuide The SHA-1 algorithm is short for the first generation of "Security Hash algorithm", and is essentially a Hash algorithm. SHA standards are mainly

In the information system, in addition to the security technology, the other important aspect is authentication technology, authentication technology is mainly used to prevent opponents to the system active attack, such as camouflage, intersymbol,
