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 codeThe BASE64 encoding requires the conversion of 3 8-bit bytes （3*8=24） to 4 6-bit bytes （4*6=24） , followed by 6 two in front of 0 bits, forming a 8-bit byte form, so that the valid bit for each byte is 6 bits

Apple Computer obtains the released SHA1 and developed SHA1 and androidsha1 versions of Android Studio. Recently, I started to switch to Android, preparing to bring my apps on Apple to Android. One of the problems I encountered was the best weather (iOS and mini apps already exist, that's worse than Android.) For the Baidu positioning function referenced, you need to enter the release version

The SHA1 values under development mode (Debug) and Release mode (release) are different, and when releasing the APK, you need to reconfigure key according to the KeyStore of the release apk, and get the method of SHA1 in the release mode refer to method two . here's how to get the SHA1 value. get SHA1 through Eclipse:W

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 that can be encrypted into a unique fixed-length code.SHA1The full name of SHA1 is secure Hash algorithm (Secure Hash algorithm).

The example in this article describes how the go language SHA1 hash of strings. Share to everyone for your reference. Specifically as follows: Copy Code code as follows: Package Main Import ( "FMT" "Crypto/md5" "CRYPTO/SHA1" "IO" ) MD5 hash of a string Func A (data string) string { T: = MD5. New (); Io. WriteString (T,data); Return FMT. Sprintf ("%x", T.sum (nil)); }

Add encryption Knowledge First: MD5 and

. The full name of SHA1 is secure Hash algorithm (Secure Hash Algorithm) The hash value of the MD5 algorithm is 128 bits in size. The hash value of the SHA1 algorithm is 160 bits in size. Both of these algorithms are irreversible. Although August 17, 2004 at the International Cryptography Conference in Santa Barbara, Calif. (Crypto ' 2004), Professor Wangxiaoyun of the University of Shandong,

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, the author will provide the MD5 value. Its function is that we can perform an MD5 verification on the downloaded files after downloading the software to ensure
