SimpleSignature

type SimpleSignature​

A basic signature

This enumeration defines the set of simple or basic signature schemes supported by IOTA. Most signature schemes supported by IOTA end up comprising of a at least one simple signature scheme.

BCS​

The BCS serialized form for this type is defined by the following ABNF:

```text simple-signature = bytes ; where the contents of the bytes are defined by ; <simple-signature-body> simple-signature-body = (ed25519-flag ed25519-signature ed25519-public-key) / (secp256k1-flag secp256k1-signature secp256k1-public-key) / (secp256r1-flag secp256r1-signature secp256r1-public-key) ```

Note: Due to historical reasons, signatures are serialized slightly different from the majority of the types in IOTA. In particular if a signature is ever embedded in another structure it generally is serialized as `bytes` meaning it has a length prefix that defines the length of the completely serialized signature.

type SimpleSignature struct {
    // contains filtered or unexported fields
}
