https://issues.dlang.org/show_bug.cgi?id=24358 Issue ID: 24358 Summary: std.digest on array of arrays surprisingly shallow Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: schveiguy gmail.com std.digest when run on an array of arrays uses a blunt cast to ubyte[], which means it digests the pointer/lengths, not the contents of the subarrays. This can be surprising, and in some cases, leave a time bomb for future uses, because strings are interned. For example: `assert (md5Of(["hello", "world"]) == md5Of(["hello", "world"]));` passes `assert (md5Of(["hello", "world"]) == md5Of(["hello".dup, "world"]));` fails. ----- I propose that digest on an array of items which contain pointers does not just cast to ubyte[], but rather uses the (slower) range mechanism of applying digest to each item individually. --
