未知数据编码
当我使用现有数据库的旧应用程序时,该数据库位于 ms-access 中,其中包含一些奇怪的数据编码,例如 48001700030E0F465075465A56525E1100121D04121B565A58 作为电子邮件地址,
这是什么类型的数据编码?我尝试过base64,但似乎没有。任何有过 ms-access 经验的人都可以告诉我这可能是什么编码吗?

above samples are surely emails and for web url it looks like this

This is vb + ms access program if that can be any help and i think it some standard encoding

While I was working with an old application with existing database which is in ms-access contains some strange data encoding such as 48001700030E0F465075465A56525E1100121D04121B565A58 as email address
What kind of data encoding is this? i tried base64 but it dosent seems that. Can anybody with previous experience with ms-access could tell me what possible encoding could this be.

from looking at web url encoding it seems 0505045D could be for http://

它似乎是编码为十六进制的字节。但我不知道这些字节意味着什么。将其解码为 ASCII 并不能揭示太多:
我注意到的事情可能有助于破解代码:
\x00\x17\x00\x03\x0e\x0fFPu
。\x12?VZX
结尾。It appears to be bytes encoded as hexadecimal. But what those bytes mean, I don't know. Decoding it to ASCII doesn't reveal much:
Things I've noticed that may help crack the code:
\x00\x17\x00\x03\x0e\x0fFPu
.\x12?VZX
.这些字符串似乎是某些二进制数据的十六进制表示。
前两位数字是字符串的长度 - 十进制,而不是十六进制 - 因此并非整个字符串都是十六进制的。
我看不到顶级域之前的 at 符号和点的位置的明确指示。似乎是反对简单的单一字母替换,例如 ROT13。
直方图不匹配 - 因此这排除了可能随后进行字符串排列的单字母替换。
The strings seem to be hexadecimal representations of some binary data.
The first two digits are the length of the string - decimal, not hexadecimal - so not the entire string is hexadecimal.
I can see no clear indication for the location of the at-sign and the dot before the top-level domain. Seems to be an indication against simple mono-alphabetic substitutions like ROT13.
The histograms don't match - so this rules out mono-alphabetic substitutions possibly followed by a permutation of the string.
