Creates a keyring pair object Creates a keyring pair object with provided account public key, metadata, and encoded arguments. The keyring pair stores the account state including the encoded address and associated metadata.

It has properties whose values are functions that may be called to perform account actions:

• address function retrieves the address associated with the account.
• decodedPkcs8 function is called with the account passphrase and account encoded public key. It decodes the encoded public key using the passphrase provided to obtain the decoded account public key and associated secret key that are then available in memory, and changes the account address stored in the state of the pair to correspond to the address of the decoded public key.
• encodePkcs8 function when provided with the correct passphrase associated with the account pair and when the secret key is in memory (when the account pair is not locked) it returns an encoded public key of the account.
• getMeta returns the metadata that is stored in the state of the pair, either when it was originally created or set via setMeta.
• publicKey returns the public key stored in memory for the pair.
• sign may be used to return a signature by signing a provided message with the secret key (if it is in memory) using Nacl.
• toJson calls another toJson function and provides the state of the pair, it generates arguments to be passed to the other toJson function including an encoded public key of the account that it generates using the secret key from memory (if it has been made available in memory) and the optionally provided passphrase argument. It passes a third boolean argument to toJson indicating whether the public key has been encoded or not (if a passphrase argument was provided then it is encoded). The toJson function that it calls returns a JSON object with properties including the address and meta that are assigned with the values stored in the corresponding state variables of the account pair, an encoded property that is assigned with the encoded public key in hex format, and an encoding property that indicates whether the public key value of the encoded property is encoded or not.
