kandi X-RAY | fpe Summary

fpe is a Go library typically used in Security, Encryption applications. fpe has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

An implementation of the NIST approved Format Preserving Encryption (FPE) FF1 and FF3 algorithms in Go. This follows the FF1 and FF3 schemes for Format Preserving Encryption outlined in the NIST Recommendation, released in March 2016. For FF1, it builds on and formalizes (differing from but remaining mathematically equivalent to) the FFX-A10 scheme by Bellare, Rogaway and Spies as defined here and here. For FF3, it formalizes the BPS scheme. A note about FF3: There was some recent cryptanalysis about the FF3 algorithm that is important to review. NIST has concluded that FF3 is no longer suitable as a general-purpose FPE method.

            segfault before main() is called in cross-compiled armhf
            Asked 2021-Sep-27 at 08:29

            I've finally cross-compiled and linked a binary on an Ubuntu Xenial x86_64 host to run on the Raspberry Pi 4's armhf.

            My toolchain's from ARM and placed in $TOOLCHAIN.

            My sysroot is a loop-mounted Raspberry OS image placed in $RASPBIAN_ROOT.

            This is a sample compilation line:

            ANSWER

            Answered 2021-Sep-27 at 08:29

            The solution I found was to cross-compile with the toolchain from raspberrypi.org and set --sysroot= to a Raspbian image. Their releases more or less follow Debian's and always support all existing Raspberry Pies.
            Both CXX and LD point to their g++, meaning it's GCC who determines linking flags. If necessary I can use -Wl,..
            Other than -Wabi-tag -D_GLIBCXX_USE_CXX11_ABI=0, CFLAGS is pretty standard.

            Raspbian changed their download URL format between Buster 10.3 (2020-02-13) and 10.4 (2020-05-28) and started providing full and lite versions. I used the latter.
            Since these images typically have almost no free space, I first extend the image file, partition (p2) and underlying filesystem, so I can install the -dev packages that satisfy the dependencies of my project by chrooting into the sysroot via quemu-arm.

            Looks like MILITARY_STAT_sERSS is only one byte long. And also the format, $MILSTAT., that you are using with that variable does not have any decode for 'G'.

            Try making MILITARY_STATUS long enough to store "Grand Total".

            Why conversion (unsigned long long)DBL_MAX (or FLT_MAX) causes raising of FE_INEXACT as well?

            ...

            ANSWER

            Answered 2021-Mar-01 at 22:48

            The code (unsigned long long)DBL_MAX has undefined behaviour, as per C11 6.3.1.4:

            When a finite value of real floating type is converted to an integer type other than _Bool, the fractional part is discarded (i.e., the value is truncated toward zero). If the value of the integral part cannot be represented by the integer type, the behavior is undefined

            Since the behaviour is undefined, "anything can happen", i.e. the behaviour is not covered by the standard.

            Handling division by zero with results in unexpected behaviour
            Asked 2020-Jul-09 at 16:39

            I was trying to handle the integer division by zero (please don't judge, I was told I had to use lib and I couldn't just use an if statement), but I needed to make sure the program would keep running (even though it's a very bad practice), instead of crashing or closing. The weird part is that the program should only handle division by zero but should exit for every other type of SIGFPE.

            SideNote: Now, I have no idea why they use names like FPU or FE or FPE when referring to integer "exceptions" (or I should say interrupts) since the standard says clearly that dividing a floating point number should return either inf or nan for 0 / 0 (tell me if I'm wrong).

            Anyway, I wrote this test code so I could better understand what I needed to do before the actual implementation. I know, it's weird to have x as a global variable but if I don't reset it, it will keep calling handle for no reason like forever....

            ...

            ANSWER

            Answered 2020-Jul-09 at 16:02

            It's defined as:

            The SIGFPE signal reports a fatal arithmetic error. Although the name is derived from “floating-point exception”, this signal actually covers all arithmetic errors, including division by zero and overflow. If a program stores integer data in a location which is then used in a floating-point operation, this often causes an “invalid operation” exception, because the processor cannot recognize the data as a floating-point number.

            There's no reason for it to be labelled specifically FPE but these sorts of labels can evolve in unpredictable ways. I wouldn't read too much into it.

            These signals are part of the POSIX standard and may not be fully supported or implemented in Windows. The Windows implementation of these support facilities is lacking in a number of areas, like how fork() is unsupported.
