Overview

Package keyring provides common key management API.

The Keyring interface

The Keyring interface defines the methods that a type needs to implement to be used as key storage backend. This package provides a few implementations out-of-the-box.

NewInMemory

The NewInMemory constructor returns an implementation backed by an in-memory, goroutine-safe map that has historically been used for testing purposes or on-the-fly key generation as the generated keys are discarded when the process terminates or the type instance is garbage collected.

New

The New constructor returns an implementation backed by a keyring library (https://github.com/99designs/keyring), whose aim is to provide a common abstraction and uniform interface between secret stores available for Windows, macOS, and most GNU/Linux distributions as well as operating system-agnostic encrypted file-based backends.

The backends: 

os	The instance returned by this constructor uses the operating system's default
	credentials store to handle keys storage operations securely. It should be noted
	that the keyring may be kept unlocked for the whole duration of the user
	session.
file	This backend more closely resembles the previous keyring storage used prior to
	v0.38.1. It stores the keyring encrypted within the app's configuration directory.
	This keyring will request a password each time it is accessed, which may occur
	multiple times in a single command resulting in repeated password prompts.
kwallet	This backend uses KDE Wallet Manager as a credentials management application:
	https://github.com/KDE/kwallet
pass	This backend uses the pass command line utility to store and retrieve keys:
	https://www.passwordstore.org/
test	This backend stores keys insecurely to disk. It does not prompt for a password to
	be unlocked and it should be used only for testing purposes.
memory	Same instance as returned by NewInMemory. This backend uses a transient storage. Keys
	are discarded when the process terminates or the type instance is garbage collected.

func New 

func New(

New creates a new instance of a keyring. Keyring options can be applied when generating the new instance. Available backends are "os", "file", "kwallet", "memory", "pass", "test".

Example 
// Select the encryption and storage for your cryptostore
cdc := getCodec()
cstore := NewInMemory(cdc)

sec := hd.Secp256k1

// Add keys and see they return in alphabetical order
bob, _, err := cstore.NewMnemonic("Bob", English, sdk.FullFundraiserPath, DefaultBIP39Passphrase, sec)
if err != nil {
	// this should never happen
	fmt.Println(err)
} else {
	// return info here just like in List
	fmt.Println(bob.Name)
}
_, _, _ = cstore.NewMnemonic("Alice", English, sdk.FullFundraiserPath, DefaultBIP39Passphrase, sec)
_, _, _ = cstore.NewMnemonic("Carl", English, sdk.FullFundraiserPath, DefaultBIP39Passphrase, sec)
records, _ := cstore.List()
for _, k := range records {
	fmt.Println(k.Name)
}

// We need to use passphrase to generate a signature
tx := []byte("deadbeef")
sig, pub, err := cstore.Sign("Bob", tx, signing.SignMode_SIGN_MODE_LEGACY_AMINO_JSON)
if err != nil {
	fmt.Println("don't accept real passphrase")
}

// and we can validate the signature with publicly available info
bRecord, _ := cstore.Key("Bob")
key, _ := bRecord.GetPubKey()
bobKey, _ := bob.GetPubKey()
if !key.Equals(bobKey) {
	fmt.Println("Get and Create return different keys")
}

if pub.Equals(key) {

}

SignatureAlgo defines the interface for a keyring supported algorithm.

func NewSigningAlgoFromString 

func NewSigningAlgoFromString(str string, algoList SigningAlgoList) (SignatureAlgo, error)

NewSigningAlgoFromString creates a supported SignatureAlgo.

type Signer 

type Signer interface {
	// Sign sign byte messages with a user key.
	Sign(uid string, msg []byte, signMode signing.SignMode) ([]byte, types.PubKey, error)

	// SignByAddress sign byte messages with a user key providing the address.
