海外TECH	DEV Community	Under the Hood: How BCrypt Functions	https://dev.to/wwwestin/under-the-hood-how-bcrypt-functions-p9p	Under the Hood How BCrypt FunctionsSomething that I often experience as a student software engineer is taking a feature of a web application that I ve used hundreds if not thousands of times before and then learning how it is implemented how it functions It s actually become one of my favorite aspects about learning the profession thus far One such concept that I ve encountered learned recently is how passwords are securely stored and accessed Of course to even get to the point of understanding the above one must first learn how a user enters that password data into a form and how that data is transferred to a database After that one can safely assume that every time you log in you re just posting the input from the password form to a database and a function checks to see if that plaintext password matches the username then you re good to go right Well if we deploy a website where the sole intention is to compromise our user s information then absolutely But that s not what we re about One of the primary tools used in securing passwords or anything regarded as sensitive information is hashing As alluded to above storing plaintext passwords puts users at risk People myself previously very much included have a strong tendency to use same or similar passwords for multiple websites and it s easy to see why It s hard to put a number on the average number of applications that a single person has to remember login credentials for but even if the number was simply five that s a lot of effort to generate a secure unique password for each platform Thus a data breach has the potential to expose a single user to multiple other breaches among other risks Hashing combats this by taking a newly minted password and generating a fixed length output This seemingly unintelligible text that the hash function generates makes password determination difficult but not impossible Given that a hash always produces a fixed length output one could take many of the available breached databases on the internet and create a reference of all these known passwords hashes and cross reference the database in question From there it s just a matching game This is where salting comes in A salt is just “simply a random string added to the beginning of a password before it is hashed This adds another layer of complexity to obtain a databases sensitive information If we could also make the hashing function very computationally expensive such that the function requires a lot of time space to re run a password string then you have a great recipe to make compromising a database at least way more effort than it s worth One broadly used cryptographic function to hash salt passwords as well as taking a very long time to do it is BCrypt As one would surmise there are many widely available cryptographic functions two examples being the SHA or SHA family Although these perform similar tasks to BCrypt they are computationally fast making brute force attacks easier In addition to the benefit of being computationally slow BCrypt also has the advantage of scalability As modern CPUs become predictably faster at computing hashes BCrypt will run slower and slower given “faster hardware So we ve gone over why BCrypt is used but how exactly does it work The function can be broken down into two phases Phase A function named “EksBlowfishSetup is called taking in the desired cost salted prepended string and the password This is where the bulk of BCrypt s time is spent generating a set of subkeys from the primary key i e the password Phase From here the bit text “OrpheanBeholderScryDoubt is encrypted times using EksBlowfish in Electronic Code Book ECB mode with the state from the previous phase This produces the cost and bit salt value concatenated with the result of the encryption loop The resulting hash will have some consistent features It ll be prefixed by either a y or b i e the algorithm identifier It ll delineate the cost in this case Then the remaining characters contain the salt password hashSimplified One algorithm EksBlowfish performs a lengthy computation based on input and the results of those computations are encrypted alongside a fixed string OrpheanBeholderScryDoubt to create a fixed length hash Once a hash is generated we need to be able to store it to be compared for authentication purposes The source code of the BCrypt Ruby Gem actually offers great insight into how this is performed in Rails First and foremost keep in mind that knowing what the password s salt is is the Password object s responsibility The given password is run through the same function as the stored with the same salt Then the results are compared to the stored hashViola The password can be verified in one line of code Resources url	2022-04-21 01:16:52
海外TECH	DEV Community	(Another) Simple Python File Renaming Script	https://dev.to/josephmads/another-simple-python-file-renaming-script-5dd1	Another Simple Python File Renaming Script IntroThis is a walk through of a file renaming script that allows the user to specify the type of file to be renamed and to choose the naming convention The Scriptimport pathlib set the directory containing the files to be renamedpath pathlib Path home joe Pictures examplePics set the new name of the files file name photos file list counter for file in sorted path glob JPG file type to rename file list append file for file in file list new file file name str counter str file suffix lower file rename path new file counter How It WorksThis directory has two file types jpg and txt For this example I only want to change the names of the jpg files First the script imports the pathlib module from the standard library Functions from this module allow the script to navigate directories iterate by file type and rename files The Path class tells the script where the files are that need to be renamed It gets assigned to the path variable import pathlibpath pathlib Path home joe Pictures examplePics If the script is run from the same directory as the files being renamed path can be written path pathlib Path cwd Next the user assigns a string to file name which will become the stem of the new file names file list initializes an empty list counter starts the file numbering scheme at file name photo file list counter The first for loop iterates over the files that path points to The glob method specifies the file type by matching the relative pattern also assigned by the user The files are sorted and appended to the file list that was initialized above for file in sorted path glob JPG file type to rename file list append file Without this first for loop there is a fringe case where the renaming script overwrites and erases some files This happens if it is run twice in a row without changing the file name string I only encountered this problem in Linux both WSL and a Linux machine when running the script from outside the working directory I could not get Windows to duplicate the problem It doesn t seem very likely that the user would run into this file erasure issue However since no one likes unexpectedly losing files I kept it in the script just to be on the safe side The second for loop iterates over the sorted files appended to file list new file is initialized and the new file name is concatenated from the string in file name the integer in counter converted to a string and the file type suffix specified in the first for loop file suffix is converted to a string and made lowercase using the lower string method for file in file list new file file name str counter str file suffix lower I made the file suffix conversion because I like my file extensions lowercase If uppercase extensions are preferred or the extensions are already lowercase the line can be written like this new file file name str counter file suffixFinally the rename method renames the file to the targeted directory path and returns a new Path instance pointing to target counter is increased by and the script loops until every specified file has been renamed file rename path new file counter After the script is run the directory looks like this Thanks for reading	2022-04-21 01:04:37
