只是部分Wp 关于原题目、扫二维码得解压密码等部分请参照其他博客,此篇博客仅记录笔者解题时碰壁的部分。 base64和rar 用010editor查看黄金6年.mp4,拖到最下面发现有需要base64解码。 在kali中进行base64解码并用 hexdump -C 以16进制和ascii码的格式输出在屏幕 echo "UmFyIRoHAQAzkrXlCgEFBgAFAQGAgADh7ek5VQIDPLAABKEAIEvsUpGAAwAIZmxhZy50eHQwAQAD Dx43HyOdLMGWfCE9WEsBZprAJQoBSVlWkJNS9TP5du2kyJ275JzsNo29BnSZCgMC3h+UFV9p1QEf JkBPPR6MrYwXmsMCMz67DN/k5u1NYw9ga53a83/B/t2G9FkG/IITuR+9gIvr/LEdd1ZRAwUEAA==" | base64 -d|hexdump -C 可以看出这个是一个rar文件。 接下来我经过1个半小时的各种尝试,确定只有得到的这个hex是完全正确的,要想保存为正确的rar文件,就要用这段hex,而把base64解码得到的ascii码放到010editor里得到的hex编码会有误。总之使用了各种途径进行解码和生成文件,均失败。最后迫不得已对着kali的输出结果在010editor里新建hex文件后手动输入进去

Storing large file within batch file

被刻印的时光 ゝ 提交于 2020-01-07 07:49:23
问题 I'm trying to create a batch file that stores one or more large files within it as base64 encoded strings, then converts them back into files. I've been following the first answer on this question: Store a file inside of a batch file? but i'm trying to store a ~3mb file within this batch file, and when it comes to writing the files source back to a file (via echo), the batch file appears to crash. I get a popup saying 'Windows Command Processor has stopped working'. Is there a limit to how

问题 I'm using Meteor with a Cordova plugin to record a video on an iPhone, then convert that to a blob for uploading. About half of the time I try to convert the video from the local filesystem to a blob it works and the other half it gives this error: InvalidCharacterError: DOM Exception 5: An invalid or illegal character was specified, such as in an XML name. It seems like it usually happens when the video is longer than 3 seconds, but it has happened on the really short videos. Here is my

js中图片base64格式转文件对象

通常我们使用裁剪工具裁剪图片后输出的格式为base64格式,而有时需要将图片转为源文件。 可用如下方法 function dataURLtoFile(dataurl, filename) {//将base64转换为文件,dataurl为base64字符串,filename为文件名(必须带后缀名,如.jpg,.png) var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1], bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n); while(n--){ u8arr[n] = bstr.charCodeAt(n); } return new File([u8arr], filename, {type:mime}); }, 来源: https://www.cnblogs.com/linfblog/p/12150719.html

Angular中实现文件转BASE64

假如想象 提交于 2020-01-06 15:25:43
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Angular中实现文件转BASE64 这是一个so easy的问题,主要是记录一下angular 的模板变量的使用和组件中匿名方法 ,箭头方法使用的区别 代码 模板文件 <div nz-col [nzSpan]="3"> <!-- 设置为 display: none ,因为 input看上去太丑 --> <input type="file" style="display: none" (change)="fileInputChange(fileInput)" multiple #fileInput /> <!-- 因为 input 设置为不可见,所以需要给用户一个可以触发 input 的按键 --> <a (click)="choseIcon(fileInput)"> <!-- img 的 src 属性绑定 组件的 icon属性的值,这个icon 属性就是转换后的base64串 --> <img alt="图标" [src]="icon" class="menu-icon"> </a> </div> 组件代码 export class MenuEditComponent implements OnInit { icon = ''; // 点击按键时触发 input的click方法 choseIcon

问题 I know there is a package called dart:convert which let me decode base64 image. But apparently, it doesn't work with pdf files. How can I decode the base64 PDF file in Flutter? I want to store it in Firebase Storage (I know how to do it) but I need the File variable to do it. I have a web service written in node js where I have a POST route. There, I create a pdf file and encode it to base 64. The response is a base64 string, look at the code. router.post('/pdf', (req, res, next) => { //res

Android: using Base64 to encode an Image to String

北慕城南 提交于 2020-01-06 08:21:36
问题 I downloaded the Base64.java from here: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2_r1.1/android/util/Base64.java which contains method encodeToString() but its very low sized compared to what i had previously. Its just some 750 lines of code. the previous 1 was downloaded from here: http://sourceforge.net/projects/iharder/files/ which has 2064 lines of code but doesn't have the method encodeToString() instead it has only encodeToFile() method.
