The ''double-SHA256'' cryptographic hash function takes an arbitrary-length data as input and produces a 32-byte hash by running the data through the SHA-256 hash function as specified in FIPS 180-4[3], and then running the same hash function again on the 32-byte result, as a protection against length-extension attacks.
The ''fast-SHA256'' cryptographic hash function takes two 32-byte hash values, concatenates these to produce a 64-byte buffer, and applies a single run of the SHA-256 hash function with a custom 'initialization vector' (IV) and without message paddding.
The ''fast-SHA256'' cryptographic hash function takes two 32-byte hash values, concatenates these to produce a 64-byte buffer, and applies a single run of the SHA-256 hash function with a custom 'initialization vector' (IV) and without message padding.
The result is a 32-byte 'midstate' which is the combined hash value and the label of the inner node.
The changed IV protects against path-length extension attacks (grinding to interpret a hash as both an inner node and a leaf).
fast-SHA256 is only defined for two 32-byte inputs.
