온라인 MD5 해시 생성기

I am woring with a numpy's 1d array with thousands of uint64 numbers in python 2.7. What is the fastest way to calculate the md5 of every number individually?

Each number has to be converted to string before calling the md5 function. I read in many places that iterating over numpy's arrays and doing stuff in pure python is dead slow. Is there any way to circumvent that?

I want to compute hash value of file.

I have Array-list holding lines of files. Now I want to compute the Hash value of it.

How can I do it using C# md5?

I am using the REST PUT BLOB API for Microsoft AZUREIt is indicated at https://docs.microsoft.com/en-us/rest/api/storageservices/put-blob :"When omitted in version 2012-02-12 and later, the Blob Service Generates an MD5 hash."

I use "x-ms-version" = "2019-02-02"The uploaded file is automatically encoded with an MD5 hash !It is also different from the uploaded file.How to avoid this?I think this is a parameter to specify ...Thanks

Computing md5 needs a stream of bytes to pass through. I'm assuming it is possible to intercept csv.writer as a stream of bytes while a million rows are written. In below py code, a million rows are written, how do I compute md5 without reading the file into memory just for md5?

def query2csv(connection, fileUri, sqlQuery, args):    import csv    tocsvfile = open(fileUri, 'w+')    writer = csv.writer(tocsvfile, delimiter=',', quotechar='"') # , quoting=csv.QUOTE_MINIMAL    #As a huge blob goes into writer, pass through, md5 how?    # I do not want to read the huge file through memory just to compute md5    with connection.cursor() as cur:        cur.execute(sqlQuery, args)        column_names = list(map(lambda x: x[0], cur.description))        writer.writerow(column_names)        writer.writerows(__batch_rows(cur))

I have three macs. I have a rails app, that I can run on two of them. On the third, I can create a new rails app and it works fine and some of my other rails apps from the other machines work fine, however the one that I need to have work on the one machine always gives me a message about not being able to find an image:

/Users/woo/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/bootsnap-1.4.5/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require': dlopen(/Users/woo/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/mysql2-0.5.3/lib/mysql2/mysql2.bundle, 9): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib (LoadError)  Referenced from: /usr/local/opt/mysql/lib/libmysqlclient.21.dylib  Reason: image not found - /Users/woo/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/mysql2-0.5.3/lib/mysql2/mysql2.bundle

I have followed suggestions about installing the mysql2 bundle using:

gem install mysql2 -v '0.5.3' -- --with-cflags=\"-I/usr/local/opt/openssl/include\" --with-ldflags=\"-L/usr/local/opt/openssl/lib\"

then bundle install, and it says all is fine. Yet 'rails s' produces that unable to find image message.

I use rbenv to manage versions and on all machines ruby is 2.6.3 and rails is 5.2.4.

What other aspects of the configuration of the app do I need to check to make sure they are the same? I have a script called 'laptop' that I obtained using:

cd ~curl --remote-name https://raw.githubusercontent.com/monfresh/laptop/master/maccurl --remote-name https://raw.githubusercontent.com/monfresh/laptop/master/Brewfile/usr/bin/env bash mac 2>&1 | tee ~/laptop.log

I run this on each machine when I am setting up to install or run a rails app. On the problem machine I do get messages like:

ERROR:root:code for hash md5 was not found.Traceback (most recent call last):  File "/usr/local/Cellar/python@2/2.7.16/Frameworks/Python.framework/Versions/2.7/lib/python2.7/hashlib.py", line 147, in <module>

during the laptop run, but at the end it says all modules were installed correctly. I have a feeling that's not really true and may be part of the problem. If so, what is causing this? I'm running OS X 10.14.6 on the machine in question.

I also notice that libssl.1.0.0.dylib is NOT present at the specified location. How do I install this and moreover, how to I make sure that all of these pieces are properly coordinated?
