PROBLEM TO BE SOLVED: To realize a simple and speedy circulation shift without operating an endian (data arrangement) transform.;SOLUTION: When operating left circulation shifting of one word data S, in which one byte is composed of b-bits and one word is composed of w-bytes, by bx+y (...
Bytecode Viewer Basically, each of these APK decompilers works differently and has its own pros and cons. So, you have to select them according to your requirements. For example, JADX is quick and convenient but sometimes resource files are partially missing in its output. So, JADX has some...

For port multiplexing, frp sends a first byte 0x17 to dial a TLS connection. This only takes effect when you set transport.tls.disableCustomTLSFirstByte to false. To enforce frps to only accept TLS connections - configure transport.tls.force = true in frps.toml. This is optional. frpc TLS...
flag[i]^=*((_BYTE*)&v2+(signedint)i%4); v2 是一个int类型: &v2: 取int的地址,也就是一个指向v2的整型指针 (byte *)&v2 :将 int 类型指针转换为 byte 类型 (byte *)&v2 + i % 4:每次取一个 byte 所以整句的意思是,每次取 key 的一个byte出来,进行xor ...

Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as00000010100101000001111010011100), return 964176192 (represented in binary as00111001011110000010100101000000). Follow up:If this function is called many times, how would you optimize it?
One embodiment includes a process for reverse lookups using a map structure and a structure being referenced by the map structure that comprises receiving a structure that comprises a reference to the structure and a reverse lookup hint; locating one or more entries in a map structure that corresp...
