hash

问题 I'm in the middle of development and I need to test my login/password api. Problem is in the database the password is encrypted. I have the following information. key iteration salt Is this enough to recover the password? By the way I can edit these values as well if that will help. 回答1: I think you misunderstood, how a password API works. You cannot reverse a properly hashed password, but you can validate an entered password against the stored hash. To validate the entered password, you need

问题 I am trying to run a one-way hash for a string column in USQL. Is there a way to do this inline? Most of the C# samples found online require multiple lines of code - which is tricky in USQL without a code-behind or compiled C# assembly. 回答1: Option 1 (Inline formula): The code below can be used to compile a SHA256 or MD5 on any string, and runs without any special dependencies and without needing a code-behind file. CREATE TABLE master.dbo.Test_MyEmail_Hashes AS SELECT cust.CustEmailAddr AS

问题 In my script I'm tracking what tab I am on in a web page using window.location.href = #!hashName1 If I then click on another tab, it will go to #!hashName2 My issue is, if I click the back button, it just goes back to the state #!hashName1. I have to then click back once again to go back another page. Is there any way to just have it go back a page and not back to the previous hash state? Thanks 回答1: u can handle back button event like this window.onhashchange = function() { goBack(); }

问题 I am looking for a more effective way to write this affect subroutine in perl: #!/usr/bin/perl use 5.010; use strict; my @keys = qw/foo bar baz/; my %hash = ( foo => {babel => 'fish'} ); affect (\%hash, 42); sub affect { my $ref = shift; $ref = $ref->{$keys[$_]} //= {} for (0.. $#keys - 1); $ref->{$keys[$#keys]} = shift; } use Data::Dumper; print Dumper \%hash; And the expected result: $VAR1 = { 'foo' => { 'bar' => { 'baz' => 42 }, 'babel' => 'fish' } }; I was thinking about things like this,

问题 I would like to create a perl style multilevel dict in python however I'm struggling to get this going. This is what I have tried: import sys import csv import pprint from collections import defaultdict hash = defaultdict(dict) FILE = csv.reader(open('dosageMP.txt', 'rU'), delimiter='\t') FILE.next() count = 0 for row in FILE: if count < 10: print row hash[row[0]][row[10]][row[5]] = 1 count = count+1 pp = pprint.PrettyPrinter(indent=4) pp.pprint(hash) This code seems to work well for two

问题 I need to take raw client text in a web form and send it back to a Tomcat servlet as JSON. For legacy reasons, this input may be formatted as a Ruby hash. I also cannot force my clients to convert their existing Ruby formatted inputs over to JSON. I could write a custom parser, but I wanted to see if a JavaScript based solution existed that would allow me to determine if a blob of text is a Ruby hash and, if so, convert it into JSON. 回答1: JSON is a Ruby standard library. You've to just

问题 I was wondering - is there any disadvantages in using the hash of something as a salt of itself? E.g. hashAlgorithm(data + hashAlgorithm(data)) This prevents the usage of lookup tables, and does not require the storage of a salt in the database. If the attacker does not have access to the source code, he would not be able to obtain the algorithm, which would make brute-forcing significantly harder. Thoughts? (I have a gut feeling that this is bad - but I wanted to check if it really is, and

问题 I have a hash like this: data = {"Blood Group"=>"A", "Next Review Date"=>"22/06/2016", "Tourniquet Time"=>"23", "BMI"=>"21"} I have a sorting order in an array: sorting_order = [1, 0, 2, 3] I want to rearrange the hash according to the sorting order array so that the hash becomes: data = {"Next Review Date"=>"22/06/2016", "Blood Group"=>"A", "Tourniquet Time"=>"23", "BMI"=>"21"} I tried: sorted_hash = sorting_order.map{|x| data[x]} It returns: NoMethodError: undefined method `[]' for #

问题 How should I convert a series of nested hashes (nested to arbitrary depth) to a series of nested OpenStructs? I'm loading in a big YAML file and I'm not enjoying accessing['everything']['like']['this'] . I have found a few partial solutions using Google, but I thought this would make a nice question here. Here is one of the solutions I found from http://andreapavoni.com/blog/2013/4/create-recursive-openstruct-from-a-ruby-hash: # deep_struct.rb require 'ostruct' class DeepStruct < OpenStruct
