The Domain Separation for Poseidon
Variants§
Merkle4
Domain to specify hashing of 4-arity merkle tree.
Note that selecting this domain-separator means that the total hash
input must be exactly 4 BlsScalar long, and any empty slots of the
merkle tree level need to be filled with the zero element.
Merkle2
Domain to specify hashing of 2-arity merkle tree
Note that selecting this domain-separator means that the total hash
input must be exactly 2 BlsScalar long, and any empty slots of the
merkle tree level need to be filled with the zero element.
Encryption
Domain to specify hash used for encryption
Other
Domain to specify hash for any other input
Trait Implementations§

impl From<Domain> for u64
Source§fn from(domain: Domain) -> Self
fn from(domain: Domain) -> Self
Encryption for the domain-separator are taken from section 4.2 of the
paper adapted to u64.
When Other is selected we set the domain-separator to zero. We can do
this since the io-pattern will be encoded in the tag in any case,
ensuring safety from collision attacks.
