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
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
# Region encrypts the specified string in MD5 Mode
//************************************** *******************************//// Security. Encrypt () method//// The encrypt method encrypts a clean string into a hashed string////*********************
First, let's introduce the concept of MD5 and SHA1.MD5The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm). 128-bit length. At present, MD5 is an irreversible algorithm.It has high security. It corresponds to any string
C # obtain the MD5 and SHA1 files,
When I first started learning programming, I always wanted to write some small software gadgets.
This is the typical file MD5 verification, and a SHA1 is added by the way.
When downloading something on the Internet,
PHP Cryptographic function-sha1 () function Encryption
First of all, let's introduce what is SHA1?
SHA is the full name: Secure Hash Algorithm (secure hashing algorithm) is mainly applied to digital signature (digital Signature standard DSS) in the
/// /// Calculate the MD5 value of a file /// /// Name and path of the file to calculate the MD5 Value /// MD5 value: A hexadecimal string Public String Md5file ( String Filename){ Return Hashfile
This paper mainly describes the process of computing the Information digest using the SHA1 algorithm.Security System (0)--encryption and decryption algorithm, message digest, message authentication technology, digital signature and public key

1.BASE64 encoding
Package Main//This syntax introduces the ENCODING/BASE64 package and uses the name b64 instead of the default base64. This saves you a bit of space.
