Summary0006182: Specifiy the details for FDH in GNU Taler
DescriptionGNU Taler requires Full Domain Hash (FDH) in the withdrawal, refresh and
deposit protocols of GNU Taler. AFAIK, the term FDH refers to a property or
requirement of the hashing+signing operation and does not define a particular
choice of hash functions and the actual algorithm to generate a value of
specific length.

GNU Taler uses a particular implementation of an FDH by eventually calling

        return GNUNET_CRYPTO_hkdf_v (result,

I suggest to be specific about the FDH algorithm that GNU Taler uses and add it
to the protocol specification(s) and documentation.
