            How to override a nested npm sub-dependency with a different package altogether (not just different package version number)?
            Asked 2022-Apr-04 at 01:19
            Overview

            I am having trouble resolving a ReDoS vulnerability identified by npm audit. My application has a nested sub-dependency ansi-html that is vulnerable to attack, but unfortunately, it seems that the maintainers have gone AWOL. As you can see in the comments section of that Github issue, to get around this problem, the community has made a fork of the repo called ansi-html-community located here, which addresses this vulnerability.

            Thus, I would like to replace all nested references of ansi-html with ansi-html-community.

            Problem

            My normal strategy of using npm-force-resolutions does not seem to be able to override nested sub-dependencies with a different package altogether but rather only the same packages that are a different version number. I have researched this for several hours, but unfortunately, the only way I have found to fix this would appear to be with yarn, which I am now seriously considering using instead of npm. However, this is not ideal as our entire CI/CD pipeline is configured to use npm.

            Does anyone know of any other way to accomplish nested sub-dependency package substitution/resolution without having to switch over to using yarn?

            Related Questions

            These are questions of interest that I was able to find, but unfortunately, they tend to only discuss methods to override package version number, not the package itself.

            I figured it out. As of October 2021, the solution using npm-force-resolutions is actually very similar to how you would specify it using yarn. You just need to provide a link to the tarball where you would normally specify the overriding version number. Your resolutions section of package.json should look like this:

            As has been commented in the comments section, the issue has been solved by moving the project folder outside the OneDrive directory.

            Because it's a synchronized cloud folder, as soon as you install/add/delete/update anything, it's being updated in the OneDrive cloud so the file/folder it's being used in the background and potentially unreachable. If at this time you try to develop the project (gatsby develop or gatsby build) and the file is being used, you won't be able to run it.

            I don't think it's a good practice to use a cloud folder because the amount of data synchronized (mainly because of the node_modules) it's something to care about (it's also ignored in the .gitignore for a reason) so moving it to any other folder outside the OneDrive directory should be enough to run your project because the rest of global dependencies, according to your logs, were successfully installed.

            ANSWER

            Answered 2022-Mar-05 at 19:03

            The short answer is that BASIC numbering is in increments of one, but programmers can and do skip some of the increments. BASIC grew out of Fortran, which also used numeric labels, and often used increments of 10. Unlike Fortran, early BASIC required numbering all lines, so that they changed from labels to line numbers.

            BASIC is numbered in increments greater than one to allow adding new lines between existing lines.

            1. Most early home computer BASIC implementations did not have a built-in means of renumbering lines.
            2. Code execution in BASIC implementations with line numbers happened in order of line number.

            This meant that if you wanted to add new lines, you needed to leave numbers free between those lines. Even on computers with a RENUM implementation, renumbering could take time. So if you wanted standard increments you’d still usually only RENUM at the end of a session or when you thought you were mostly finished.

            Speculation: Programmers use increments of 10 specifically for BASIC line numbers for at least two reasons. First, tradition. Fortran code from the era appears to use increments of 10 for its labels when it uses any standard increments at all. Second, appearance. On the smaller screens of the era it is easier to see where BASIC lines start if they all end in the same symbol, and zero is a very useful symbol for that purpose. Speaking from personal experience, I followed the spotty tradition of starting different routines on hundreds boundaries and thousands boundaries to take advantage of the multiple zeroes at the beginning of the line. This made it easier to recognize the starts of those routines later when reading through the code.

            BASIC grew from Fortran, which also used numbers, but as labels. Fortran lines only required a label if they needed to be referred to, such as with a GO TO, to know where a loop can be exited, or as a FORMAT for a WRITE. Such lines were also often in increments greater than 1—and commonly also 10—so as to allow space to add more in between if necessary. This wasn’t technically necessary. Since they were labels and not line numbers, they didn’t need to be sequential. But most programmers made them sequential for readability.

            In his commonly-used Fortran 77 tutorial, Erik Boman writes:

            Typically, there will be many loops and other statements in a single program that require a statement label. The programmer is responsible for assigning a unique number to each label in each program (or subprogram). The numerical value of statement labels have no significance, so any integer numbers can be used. Typically, most programmers increment labels by 10 at a time.

            BASIC required that all lines have numbers and that the line numbers be sequential; that was part of the purpose of having line numbers: a BASIC program could be entered out of order. This allowed for later edits. Thus, line 15 could be added after lines 10 and 20 had been added. This made leaving potential line numbers between existing line numbers even more useful.

            If you look at magazines with BASIC program listings, such as Rainbow Magazine or Creative Computing, you’ll often see numbers sandwiched somewhat randomly between the tens. And depending on style, many people used one less than the line number at the start of a routine or subroutine to comment the routine. Routines and DATA sections might also start on even hundreds or even thousands.

            Programmers who used conventions like this might not even want to renumber a program, as it would mess up their conventions. BASIC programs were often a mass of text; any convention that improved readability was savored.

            Ten was a generally accepted spacing even before the home computer era. In his basic basic, second edition (1978, and expecting that the user would be using “a remote terminal”), James S. Coan writes (page 2):

            It is conventional although not required to use intervals of 10 for the numbers of adjacent lines in a program. This is because any modification in the program must also have line numbers. So you can use the in-between numbers for that purpose. It should be comforting to know at this point that the line numbers do not have to be typed in order. No matter what order they are typed in, the computer will follow the numerical order in executing the program.

            There are examples of similar patterns in Coan’s Basic Fortran. For example, page 46 has a simple program to “search for pythagorean triples”; while the first label is 12, the remaining labels are 20, 30, and 40, respectively.

            He used similar patterns without increments of 10; for example, on page 132 of Basic Fortran, Coan uses increments of 2 for his labels, and keeps the calculation section of the program in the hundreds with the display section of the program in the two hundreds. The END statement uses label 9900.

            Similarly, in their 1982 Elementary BASIC, Henry Ledgard and Andrew Singer write (page 27):

            Depending on the version of Basic you are using, a line number can consist of 1 to 4 or 5 digits. Here, all line numbers will consist of 4 digits, a common practice accepted by almost every version of Basic. The line numbers must be in sequential order. Increasing line numbers are often given in increments of 10, a convention we will also follow. This convention allows you to make small changes to a program without changing all the line numbers.

            And Jerald R. Brown’s 1982 Instant BASIC: 2nd Astounding Edition (p. 7):

            You don’t have to enter or type in a program in line number order. That is, you don’t have to enter line 10 first, then line 20, and then line 30. If we type in a program out of line number order, the computer doesn’t care. It follows the line numbers not the order they were entered or typed in. This makes it easy to insert more statements in a program already stored in the computer’s memory. You may have noticed how we cleverly number the statements in our programs by 10's. This makes it easy to add more statements between the existing line numbers -- up to nine more statements between lines 10 and 20, for example.

            Much of the choice of how to number lines in a BASIC program was based on tradition and a vague sense of what worked. This was especially true in the home computer era where most users didn’t take classes on how to use BASIC but rather learned by reading other people’s programs, typing them in from the many books and magazines that provided program listings. The tradition of incrementing by 10 and inserting new features between those increments was an obvious one.

            You can see it scanning through old books of code, such as 101 BASIC Computer Games. The very first program, “Amazin” increments its line numbers by 10. But at some point, a user/coder decided they needed an extra space after the code prints out how many dollars the player has; so that extra naked PRINT is on line 195. And the display of the instructions for the game are all kept between lines 100 and 109, another common pattern.

            The program listing on page 30 for Basket displays the common habit of starting separate routines at even hundreds and thousands. Line numbers within those routines continue to increment by 10. The pattern is fairly obvious even though new features (and possibly other patterns) have added several lines outside the pattern.

            As BASIC implementations began to get RENUM commands, more BASIC code listings appeared with increments of one. This is partly because using an increment of one used less memory. While the line number itself used a fixed amount of RAM (with the result that the maximum line number was often somewhere around FFFF, or 65525), references to line numbers did not tend to use a fixed length. Thus, smaller line numbers used less RAM overall.

            Depending on how large the program was, and how much branching it used, this could be significant compared to the amount of RAM the machine itself had.

            For example, I recently typed in the SKETCH.BAS program from the October 1984 Rainbow Magazine, page 97. This is a magazine, and a program, for the TRS-80 Color Computer. This program uses increments of 1 for its line numbering. On CLOADing the program in, free memory stands at 17049. After using RENUM 10,1,10 to renumber it in increments of 10, free memory stands at 16,953.

            A savings of 96 bytes may not sound like much, but this is a very small program; and it’s still half a percent of available RAM. The difference could be the difference between a program fitting into available RAM or not fitting. This computer only has 22823 bytes of RAM free even with no program in memory at all.

            SSIS Flow is literally like this (AllQuotes_View) > (Data Convertion) converting from nvarchar to "String [DT_STR]" 100 length, codepage (1252 ANSI - Latin I) for the column in question" > (AllQuotes_Table)

            Destination table create code

            It means some unprintable character is coming in the original product_sku, which is not able to converted to VARCHAR datatype. I would suggest you to do the below, as part of the data pull.

            Since the \ is an escape character, I think you just need to double its presence in all the strings.

            How to Derive the Key and Initial Vector in Node.js
            Asked 2022-Jan-04 at 12:24

            I have a shared key that I need to derive an iv from so I can decipher.

            The apple business chat docs state:

            Generate the Derived Key and Initial Vector Run the shared key through the X9.63 Key Derivation Function with SHA256 hash function. This results in a 48-byte payload. Your results should be rV3qrszd0PMPgeRhNnlOYA==

            Heres what I tried. I used scryptSync and pbkdf2Sync crypto functions with many 'salt' configurations. I'm unsure if these are the correct functions for this job.

            ...

            ANSWER

            Answered 2022-Jan-04 at 11:46

            X9.63 KDF is a key derivation function, described e.g. here and here. scrypt and PBKDF2 are also KDFs, but different ones, so of course the expected result cannot be reproduced with them.

            So you need a NodeJS library that supports X.963 KDF. If you can't find one, you could also implement your own.

            X9.63 KDF expects a shared secret and a shared info and determines a keysize large key as follows:

            • Create a 4 byte counter ci which is incremented starting with 0x0000001.
            • Concatenate the data conci = shared secret | ci | shared info
            • Hash the result hashi = hash(conci)
            • Concatenate the hashes hash1 | hash2 | ... until an output of length keysize has been generated.

            More formally, including various checks, the algorithm is described in the links above. The Python code posted later in the question also implements this logic.

            One possible NodeJS implementation (omitting the checks from the specification) is:
