Read Catalogue First, Base64 code Second, MD5, SHA1, SHA256, SHA512, HMAC implementation GitHub Code It is said that today 520 is a good day, why I think of 502, 500, 404 these? Fortunately the server is OK!First, Base64

usually, the encryption algorithm used is simple and efficient, the key is short, the encryption and decryption speed is fast, the decoding is extremely difficult. This article describes the use of Md5/sha1,dsa,desede/des,diffie-hellman. The

Work sometimes need to calculate the string md5/sha1 to calculate or verify the password, Linux, unlike OS X can directly use the-s parameter, now summarize the commonly used methods.1. printf "string" |md5sum/sha1sum2. Echo-n "string"

Problem: When I do user login, the background API needs to MD5 the encryption of the number and request time of the merged strings, so on the GitHub to find an encrypted frame, link: https://github. (ox) Com/paulery2014/cocoasecurity, I wrote a

Implement base64 md5 sha1 password encryption in javascript, base64sha1 1. base64 Encryption Introduce the base64.js file to the page. The call method is as follows: base64 encryption 2. md5 Encryption REFERENCE The md5.js file on the

Digest algorithm MD5, SHA1 introduction and application instance code in Python, pythonsha1 For algorithm learning, I think most of the algorithms in programming languages are in the same place. The main aspect is to understand what this algorithm

1.MD5 algorithmNon-reversible128-bit or 64-bit string, byte digit length is 16 and 8, the general expression is to use the 16 binary to represent, 1 byte is converted to 2 16bit, representing the high status, so the generated string is 16 bit or 32

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

Using Python for file hash calculations there are two points to note:1, file Open the way must be binary mode, both open the file when using B mode, or hash calculation is based on the text that will get the wrong file hash (online to see someone

1. [Code]MD5String str = "abc"// with . NET generated MD5 method, the generated content is consistent with Java:String str = "ABC" "MD5");2. [Code]SHA1String str = "abc"// with . NET generates SHA1 in the same way that the generated content is
