问题描述：

更改文件名会影响文件的MD5哈希值吗?

Will changing a file name effect the MD5 Hash of a file?

答

仅在哈希计算中包含文件名时.例如，使用伪代码:

Only if the file's name was included in the hash calculation. e.g., in pseudo-code:

$hash1 = md5(contents of file);
$hash2 = md5(name of file + contents of file);

将产生两个单独的哈希.

will produce two seperate hashes.
