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

Hash table, which is based on the high-speed access point of view design, but also a typical " space-time " approach. As the name implies, the data structure can be understood as a linear table, but the elements are not tightly arranged, but there

The hash table, which is based on the fast access angle design, is also a typical " space-time " approach. As the name implies, the data structure can be understood as a linear table, but the elements are not tightly arranged, but there may be
