Source author Wang HuiChapter 4 Basic Knowledge 1.1. Single-key password systemThe single-key cryptography system is a traditional encryption algorithm, which means that the sender and receiver of the information use the same key for encryption and decryption. Generally, the encryption algorithm is simple and efficient, the key is short, the

Android, backstage have a unified. We can see that OC is using the Kccoptionpkcs7padding alignment method. In Java, it is clear that pkcs5padding is used. Let's take a look at the alignment choices given in OC, which I'll show directly in the form of code:enum { /**/ kccoptionpkcs7padding 0x0001, Kccoptionecbmode 0x0002 /* */};The two options given in OC are Kccoptionecbmode and kccoptionpkcs7padding. Well, the problem now arises. There are many kinds of

Problem Description:Des encryption is used recently and is consistent with the results of Java's cipher class encryption. The cliper of Java has not been studied, but in work cipher generates a string based on the Des/cbc/pkcs5padding encryption method.In comparison, this string is formatted directly with the NSData ge
