问题 In WebAuthn, the authenticator data contains the variable length attested credential data followed by the extensions , if any: The attested credential data is made variable because of the credential public key field which is a CBOR map. In case there are extensions, how to know in advance the byte length of this field, so that I can pass this field truncated without the extensions to a CBOR library? The CBOR library I am using doesn't seem to handle extra bytes, and I don't know CBOR enough

问题 I'm pulling the following line of data from an API. The data starts with a b prefix which would indicate according to the Python 3.3 documentation that we are dealing with "a bytes literal" with the escape sequences \t and \n representing the ASCII Horizontal Tab (TAB) and ASCII Linefeed (LF) respectively. b'settlement-id\tsettlement-start-date\tsettlement-end-date\tdeposit-date\ttotal-amount\tcurrency\ttransaction-type\torder-id\tmerchant-order-id\tadjustment-id\tshipment-id\tmarketplace

问题 I had wrote a node/ssjs program that makes: Tcp connection to data server(Apache MIMA), using TLS module. (OK) Encode/decode(serialize/deserialize) messages through protobuffer module.. (OK) Send serialized message to server and get response. (Not OK). The server´s manual types: Structure of message: [ Length | Header length | Header (| Body length |Body) ] Length – message length = fixed size (4 bytes). Note that this is only the size of following message (not the prefix itself); Header

问题 This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. Closed 6 years ago . Why is it that sizeof("Bill") is 5 but sizeof(char) is 1 ? Shouldn't that make sizeof("Bill") be 4 since the length of the string is 4 chars ( 4 x 1 )? I

问题 I have an array with 16 elements. I would like to evaluate these to a boolean 0 or 1 and then store this in 2 bytes so i can write to a binary file. How do I do this? 回答1: Something like this you mean? unsigned short binary = 0, i; for ( i = 0; i < 16; ++i ) if ( array[i] ) binary |= 1 << i; // the i-th bit of binary is 1 if array[i] is true and 0 otherwise. 回答2: You have to use bitwise operators. Here's an example: int firstBit = 0x1; int secondBit = 0x2; int thirdBit = 0x4; int fourthBit =

问题 The dataFile.bin is a binary file with 6-byte records. The first 3 bytes of each record contain the latitude and the last 3 bytes contain the longitude. Each 24 bit value represents radians multiplied by 0X1FFFFF This is a task I've been working on. I havent done C++ in years so its taking me way longer than I thought it would -_-. After googling around I saw this algorthim which made sense to me. int interpret24bitAsInt32(byte[] byteArray) { int newInt = ( ((0xFF & byteArray[0]) << 16) | (

问题 I need get size of array in perl, but size must to be in bytes. I can not find any function for this. Thanks in advance 回答1: You can do this using the Devel::Size module -> https://metacpan.org/pod/Devel::Size #!/usr/bin/perl use strict; use warnings; use Devel::Size qw(total_size); my @arr = (1, 2, 3, "Foo", "Bar", "Baz", [4, 5, 6], {xyz => 2048}); print "Size: ", total_size(\@arr), " bytes.\n"; On my system this prints: bria@hel:~$ ./size.pl Size: 765 bytes. bria@hel:~$ 来源： https:/

问题 I need to get values in UInt16 and UInt64 as Byte[] . At the moment I am using BitConverter.GetBytes , but this method gives me a new array instance each time. I would like to use a method that allow me to "copy" those values to already existing arrays, something like: .ToBytes(UInt64 value, Byte[] array, Int32 offset); .ToBytes(UInt16 value, Byte[] array, Int32 offset); I have been taking a look to the .NET source code with ILSpy, but I not very sure how this code works and how can I safely

问题 I have a page in JSP that list some file that could be downloaded by a user. Thoses files are not on the local server, they are on a remote file server. When the user click to download a file, the webserver connect via TCP to the file server. The web server download the file and create a HTTP response for the client. Here is my code: <%@page language="java"%> <%@page import="sun.misc.Request"%> <%@page import="listing.ClientTCPStockage"%> <%@page import="java.net.InetAddress"%> <% out
