获取已编码的不可打印字符串的字节

Question

当我使用带有--hex键的sqlmap转储表条目时，我正确地获得了密码哈希字节，但powershell将这些字节表示为字符串。所有不可打印的字符都被转义，我将这些字节作为\\?e1\n\\?dc9I\\?baY\\?ab\\?beV\\?e0W\\?f2\x0f\\?88>。我怎样才能从这个字符串中取出来获取原始字节呢？

Answer 1

从字符串到字节将取决于它是否是每个字节的字符串，如果是这样的话，试试这个：

# simulated output as a byte per string
$str = [string[]][char[]][byte[]](0xE1,0x0A,0xDC,0x39,0x49,0xBA,0x59,0xAB,0xBE,0x56,0xE0,0x57,0xF2,0x0F,0x88,0x3E)

# convert to bytes
$str | Foreach {[byte][char]$_}

如果是单个字符串，请尝试：

# simulated output as a single string containing all the bytes
$ofs=''
$str = [string][char[]][byte[]](0xE1,0x0A,0xDC,0x39,0x49,0xBA,0x59,0xAB,0xBE,0x56,0xE0,0x57,0xF2,0x0F,0x88,0x3E)

# convert to bytes
$str.ToCharArray() | % {[byte]$_}
