Hash value in the manifest file.

Question

Hello, Im tring to create a manifest for my own.dll, i took the manifest file from C:\WINDOWS\WinSxS\Manifests for example. In that, below tag was one of the line.<file name="msvcr90.dll" hashalg="SHA1" hash="e0dcdcbfcb452747da530fae6b000d47c8674671">

In above tag, hash value was assigned with 40 character. Here comes my doubt, 1) hash value was auto generated, if not, whats it points to?

Answer 1

I'm not sure what your question is but it's readily apparent that the hash value is the hash value of msvcr90.dll computed with the SHA1 hash-algorithm.
