sha256 length

At present, it can be realized: MD5 algorithm, SHA256 algorithm, first MD5 SHA256, SHA256 after MD5, two MD5, two times SHA256, 8-bit MD5 algorithm after the first 8-bit SHA256, 8-bit SHA256 algorithm after the former 8-bit MD5 algorithm, Password

* * about the use of AES encryption and SHA256 encryption used in IOS development **The author in the previous period of time on this issue with the background of the docking of people, and finally finally determine the problem is our encryption,

1. To calculate the SHA256 or MD5 value of the file in the browser, the basic idea is to use the HTML5 FileReader interface to read the file into memory (Readasarraybuffer), and then get the binary contents of the file. Then get the shaa256 or MD5

In the previous article we analyzed the principle of Sha, and took SHA1 as an example to implement the relevant algorithm, in this one we will further analyze SHA2 and realize it.1 , SHA Brief IntroductionAs we have already explained in the previous

1. Brief descriptionOpenSSL offers a wealth of cryptographic tools, some commonly used hashing algorithmsFor example, Md5,sha can be used directly with the provided md5.h, sha.h interface;For the convenience of developers, OpenSSL also provides an

1. Summary of information and digital signatureInformation Summary: Processing the data to obtain a fixed length of the results, its characteristics input:1, the output length is fixed. That is, the output length is independent of the input length.2,
