SignatureScheme(schemeNumberID: Int, schemeCodeName: String, algorithmName: String, sig: Signature, keyFactory: KeyFactory, keyPairGenerator: KeyPairGeneratorSpi, algSpec: AlgorithmParameterSpec?, keySize: Int, desc: String)

This class is used to define a digital signature scheme.

Parameters

schemeNumberID - we assign a number ID for more efficient on-wire serialisation. Please ensure uniqueness between schemes.

schemeCodeName - code name for this signature scheme (e.g. RSA_SHA256, ECDSA_SECP256K1_SHA256, ECDSA_SECP256R1_SHA256, EDDSA_ED25519_SHA512, SPHINCS-256_SHA512).

algorithmName - which signature algorithm is used (e.g. RSA, ECDSA. EdDSA, SPHINCS-256).

sig - the Signature class that provides the functionality of a digital signature scheme. eg. Signature.getInstance("SHA256withECDSA", "BC").

keyFactory - the KeyFactory for this scheme (e.g. KeyFactory.getInstance("RSA", "BC")).

keyPairGenerator - defines the Service Provider Interface (SPI) for the {@code KeyPairGenerator} class. e.g. KeyPairGenerator.getInstance("ECDSA", "BC").

algSpec - parameter specs for the underlying algorithm. Note that RSA is defined by the key size rather than algSpec. eg. ECGenParameterSpec("secp256k1").

keySize - the private key size (currently used for RSA only).

desc - a human-readable description for this scheme.
