AssemblyAlgorithmIdAttribute: Why would anyone use this?

AssemblyAlgorithmIdAttribute

Why would you care what algorithm the CLR uses to hash the files in your assembly? When would you use this attribute?

  1. Hash algorithm could depend on the size of files / time required to get hash and picked during compilation time. I.e.:

    • for small files one hash algorithm might perform faster
    • for sparse files some other algorithm
    • for large ones - third one etc... - evaluation of the most efficient hashing algorithm could be done once in order to decrease time spent on checks later (although its quite unlikely done in this way :) )

  2. AssemblyAlgorithmIdAttribute also provides forward compatibility for future versions of hashing algorithms.

  3. It could also depend on framework version - actual algorithm could've changed already since .net 1.1

May be if I am planning to read assembly from a non CLR program or in other words I am interested in manually reading the contents of assembly I can use the exact hash algorithm to decode the data contained in the assembly.
