我有以下几行代码:
%for RSA Algorithm
clc;
disp('Implementation of RSA Algorithm');
clear all;
close all;

q = input('\nEnter value of q: ');
[Pk,Phi,d,e] = init(p,q);

x=length(M);

我需要把视频解码成帧。我可以在mime类型的视频中这样做,但是它不适用于
for (int i = 0; i < extractor.getTrackCount(); i++) {
MediaFormat format = extractor.getTrackFormat(i);
String mime = format.getString(MediaFormat.KEY_MIME);
System.out.println(mime);
if (mime.sta
客户端:
int[] handshake_payload = {0x00,0x04,0x12A,0x01,0x06,0x135959}; //an array of hex values to be sent
for(int n:handshake_payload)
dataOutputStream.write(n);
dataOutputStream.flush();
服务器:
int tag = dataInputStream.readUnsignedByte();
System.out.println("Tag:"+St
我正在研究Java是如何计算int的位集的。
我的脑海中有这样一个简单的东西(我认为它是正确的):
public static int bitCount(int number){
final int MASK = 0x1;
int count = 0;
for(int i = 0; i < 32; i++){
if(((number >>> i) & MASK) == MASK){
count++;
}
我通过openssl使用ECDSAwithSHA256(OID=1.2.840.10045.4.3.2)创建了一个X.509证书。
ECC参数为secp256r1。
下面是signatureAlgorithm和signatureValue。
30 0A 06 08 2A 86 48 CE 3D 04 03 02 // signatureAlgorithm field
03 49 // the starts of signatureValue indicating bitstring length of 0x49 bytes.
00 // what is this?
30 46 // the
