trait Recover[A]

Type class for recovering public keys from ECDSA signatures.

Provides a type-safe interface for recovering the public key that was used to create a signature. The recovery process first hashes the value using Hash, then uses the signature's recovery parameter to recover the public key.

Type parameters

A: the type of value that was signed

Attributes

See also

Sign for signature creation

Signature for the signature representation

CryptoOps.recover for the underlying recovery operation

Example

 import Recover.ops.*
 val keyPair   = CryptoOps.generate()
 val message   = Utf8("hello")
 val signature = keyPair.sign(message).toOption.get
 // Recover public key from signature
 val hash                                           = message.toHash
 val recovered: Either[SigilarisFailure, PublicKey] =
   hash.recover(signature)
 assert(recovered.contains(keyPair.publicKey))
