Be aware that not all versions of libcgrypt support all hash algorithms; the
constructor will throw if the specified algorithm is not supported by the
run-time version of libgcrypt. However, if the constructor does not throw,
it is safe to assume it will never throw for the same set of parameters
(except for the fatal situation that libgcrypt failed allocating memory).
