Analysis of four basic encryption algorithms in Java   Simple java encryption algorithms include: 1. BASE64 Base64 is one of the most common encoding methods used to transmit 8-bit code on the network. For details, refer to RFC2045 ~ RFC2049,

This article describes how to solve the inconsistency between AES encryption and other languages in Node. js. For example, if you need to communicate with C # and JAVA, refer Example 1: These days have been plagued by a problem. The AES encryption

Example 1: These days have been plagued by a problem. The AES encryption of Nodejs is inconsistent with that encrypted by Java and C. Of course, you cannot decrypt it. Tangle for a long time: Later, it was not enough. I read the source code, or else

MD5 and RSA are the two most commonly used algorithms in network transmission. After understanding the principles of these two algorithms, you can get a general idea of what encryption is like. However, these two algorithms use different

This article mainly talks about encryption and digital signature in cryptography, and how to use it in java. For partners interested in cryptography, we recommend that you read Bruce Schneier's book: Applied Crypotography. Security has been greatly
