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

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
