pub struct Signature { /* private fields */ }
Expand description

A Ristretto Schnorr signature “detached” from the signed message.

These cannot be converted to any Ed25519 signature because they hash curve points in the Ristretto encoding.

Implementations

Convert this Signature to a byte array.

Construct a Signature from a slice of bytes.

We distinguish schnorrkell signatures from ed25519 signatures by setting the high bit of byte 31. We return an error if this marker remains unset because otherwise schnorrkel signatures would be indistinguishable from ed25519 signatures. We cannot always distinguish between schnorrkel and ed25519 public keys either, so without this market bit we could not do batch verification in systems that support precisely ed25519 and schnorrkel.

We cannot distinguish amongst different SigningTranscript types using these markey bits, but protocol should not need two different transcript types.

Depricated construction of a Signature from a slice of bytes without checking the bit distinguishing from ed25519. Deprecated.
