Imitating what is done by the mint in its test's handlers, I had some functions in the wallet which rely on GNUNET_CRYPTO_kdf. Their purpose was to generate in advance the expected value from the /test case in order to match it with what received by the mint.
For example, the wallet can generate the init. vector, symmetric key and the 'hash key'.
(Namely, the functions are WRALLgenSymmetricKey, WRALLgenInitVector and WRALLgenKeyFromBlob in content/lib/actions.jsm)

Is that enough for closing this bug?
