Consider the string format requires the double of the bytes than the 128 bit number when stored or in memory.Your 128-bit key is still 19 bits longer, which multiplies the time by 500,000. This is how my key looks in raw format from the byte array into chars: So I take the bytes and encode it like this. 如果您需要位形式的字节，请使用我们的字符串到二进制位 .An AES 128-bit key can be expressed as a hexadecimal string with 32 characters.The most simple one would be doing the modulo operation between an input number (an integer representation of your string, for example) and the maximum number that can be represented in n bits (in your case, 128); the output result will be an n-bit number that you can convert to whatever form you want (probably hexadecimal) and use . A message is called plain text before it gets encrypted with a key. finally, reverse the string of decimal digits. This should be easy to convert to code. In computing, quadruple precision (or quad precision) is a binary floating-point –based computer number format that occupies 16 bytes (128 bits) with precision at least twice the 53-bit double precision .
