create sha1

Preface: Use Baidu map when need secret key, request secret key need SHA1 value, so today summarizes how to get this value.Under normal circumstances:First, get the development version of SHA1:Here I directly use the command console provided by

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 (

/// /// 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

MD5 's full name is Message-digest algorithm 5 (Information-Digest algorithm), in the early 90 by MIT Laboratory for Computer Science and RSA Data Security Inc Ronald L. Riv EST developed, through the development of MD2, MD3 and MD4. Its role is to

In the use of Baidu map in order to obtain key, you need to enter the release version SHA1 code and debug version SHA1 code. First, according to the official command to obtain the debug version of SHA1 code: Development mode using Debug.keystore,

Ask, If I transcode this way, is it more secure. For example: sha1 (md5 (password) I want to know: 1 is necessary. 2. if so, will it have a great impact on performance or what else I can't think, what problems may occur in the future, etc. I hope
