[−][src]Trait signature::PrehashSignature
This is supported on
feature="digest-preview" only.Marker trait for Signature types computable as 𝐒(𝐇(𝒎))
i.e. ones which prehash a message to be signed as 𝐇(𝒎)
Where:
𝐒: signature algorithm𝐇: hash (a.k.a. digest) function𝒎: message
This approach is relatively common in signature schemes based on the Fiat-Shamir heuristic.
For signature types that implement this trait, when the derive-preview
Cargo feature is enabled a custom derive for Signer is available for any
types that impl DigestSigner, and likewise for deriving Verifier for
types which impl DigestVerifier.
