UserSignatureInterface

type UserSignatureInterface

A signature from a user

A `UserSignature` is most commonly used to authorize the execution and inclusion of a transaction to the blockchain.

BCS

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

```text user-signature = bytes ; where the contents of the bytes are defined by ; <user-signature-body> user-signature-body = (%d00 ed25519-signature ed25519-public-key) / (%d01 secp256k1-signature secp256k1-public-key) / (%d02 secp256r1-signature secp256r1-public-key) / (%d03 multisig-aggregated-signature) / (%d06 passkey-authenticator) / (%d07 move-authenticator) ```

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.
