sha1

问题 I am getting following results: C:\Program Files\Java\jdk1.7.0\bin>keytool -list -alias androiddebugkey -keystor e "C:\Documents and Settings\Administrator.android\debug.keystore" -storepass a ndroid -keypass android androiddebugkey, May 27, 2011, PrivateKeyEntry, Certificate fingerprint (SHA1): "Some Code" But after entering this in http://code.google.com/android/maps-api-signup.html for getting MAP API it is showing invalid fingerprint. Can you please guide me is the fingerprint I have got

问题 I would like to check for author's e-mail and name, surname to verify who's pushing to my repo. Is there any way that I can come up with a command in git to show commiter's name/e-mail given only SHA1 of the commit? This is what I came up with but it's far from ideal solution (the first solution is for git hook that's why it's using 2 SHA1s with rev-list . The second one simply uses git show ): git rev-list -n 1 --pretty=short ccd3970..6ddf170 | grep Author | cut -d ' ' -f2- | rev | cut -d '

问题 I don't want to calculate a file's checksum, just to know if a given string is a valid checksum 回答1: SHA1 verifier: public boolean isValidSHA1(String s) { return s.matches("^[a-fA-F0-9]{40}$"); } MD5 verifier: public boolean isValidMD5(String s) { return s.matches("^[a-fA-F0-9]{32}$"); } 回答2: Any 160-bit sequence is a possible SHA1 hash. Any 128-bit sequence is a possible MD5 hash. If you're looking at the hex string representations of them, then a sha1 will look like 40 hexadecimal digits,

问题 We are building a Restful service using Grails framework and are providing security for it using Spring Security plugin. I wanted to check with you all on best approach to take when you want to authenticate using Custom Authorization header. More on this approach can be read here Custom HTTP Authorization Header In my case, client id and secret is stored in Ldap and header comes with SHA1 encryption. What would be the best approach to implement this using Spring Security? I have asked same

问题 The title of the question says it all. I have been researching SHA-1 and most places I see it being 40 Hex Characters long which to me is 640bit. Could it not be represented just as well with only 10 hex characters 160bit = 20byte. And one hex character can represent 2 byte right? Why is it twice as long as it needs to be? What am I missing in my understanding. And couldn't an SHA-1 be even just 5 or less characters if using Base32 or Base36 ? 回答1: One hex character can only represent 16

问题 i am trying to setup my android app to use firebase dynamic links and am experiencing a problem in setting it up in the firebase console. i had previously added my app to my firebase project to use the realtime database and it works with no isssues. i included the app's debug SHA-1 (which i obtained from the app-debug.apk). now in the firebase dynamic links console screen, i can select my app from the drop-down list but it shows a warning in red "Please add SHA-1 for this Android app". i even

问题 I borrowed the HMAC-SHA1 Java code from http://tools.ietf.org/html/rfc6238 and adapted slightly to hardcode it to use one known key/message pair with known output. I then tried to write the same code in Python to verify the results, however I'm getting different values in Python and Java. The Java values are known to be good. Java code: import java.lang.reflect.UndeclaredThrowableException; import java.security.GeneralSecurityException; import java.text.DateFormat; import java.text

问题 We're trying to settle an internal debate on our dev team: We're looking for a 64-bit PHP hash function. We found a PHP implementation of MurmurHash3, but MurmurHash3 is either 32-bit or 128-bit, not 64-bit. Co-worker #1 believes that to produce a 64-bit hash from MurmurHash3, we can simply slice the first (or last, or any) 64 bits of the 128-bit hash and that it will be as collision-proof as a native 64-bit hash function. Co-worker #2 believes that we must find a native 64-bit hash function
