Go from original Android studio to get the most detailed method for developing the SHA1 value and release SHA1 value of the versionObjective:Today I want to integrate the positioning of Baidu map into the project, want to write a small case, to achieve, but in the integration of Baidu map first to apply for the secret key, the application of the secret key to use the SH

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

of this commit. As mentioned earlier, the Git branch is essentially a pointer to a commit object. The merging of two git branches is essentially equivalent to the merging of two forward-free graphs, whereas a forward-free graph can make Git more efficient in judging the branch's parent node. As a result, the Git objec

SHA1 hashes is frequently used to compute short identities for binary or text blobs. For example, the GIT revision control system uses SHA1 extensively to identify versioned files and directories. Here's how to compute SHA1 hashes in Go

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).

Verifying the integrity of downloaded files under Linux (MD5,SHA1,PGP)
Http://blog.useasp.net/archive/2014/03/29/use-md5-sha1-or-pgp-to-check-downloaded-file-integrity-on-linux.aspx
Linux is always difficult to learn, but sometimes, but found that Linux is far more than the operation of Windows is much more-the integrity of the download file is one of them, let me feel very cool
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

Some people often ask, what is the difference between CRC, MD5, and sha1 when calculating a verification value? I hope the descriptions below will give you an understanding.
Similarities:
CRC, MD5, and sha1 are calculated to generate a verification value, which is used to verify data integrity.
Differences:
1.AlgorithmDifferent. CRC adopts polynomial Division, while MD5 and
