Classes

Keypair

Methods

canSign() → {boolean}

Returns true if this Keypair object contains secret key and can sign.

Source:

js-stellar-base/src/keypair.js, line 206

Returns:

Type:: boolean

publicKey() → {string}

Returns public key associated with this Keypair object.

Source:

js-stellar-base/src/keypair.js, line 174

Returns:

Type:: string

rawPublicKey() → {Buffer}

Returns raw public key

Source:

js-stellar-base/src/keypair.js, line 160

Returns:

Type:: Buffer

rawSecretKey() → {Buffer}

Returns raw secret key.

Source:

js-stellar-base/src/keypair.js, line 198

Returns:

Type:: Buffer

secret() → {string}

Returns secret key associated with this Keypair object

Source:

js-stellar-base/src/keypair.js, line 182

Returns:

Type:: string

sign(data) → {Buffer}

Signs data.

Source:

js-stellar-base/src/keypair.js, line 215

Parameters:

Name	Type	Description
`data`	`Buffer`	Data to sign

Returns:

Type:: Buffer

signDecorated(data) → {xdr.DecoratedSignature}

Returns the decorated signature (hint+sig) for arbitrary data.

Source:

js-stellar-base/src/keypair.js, line 242

See:

TransactionBase.addDecoratedSignature

Parameters:

Name	Type	Description
`data`	`Buffer`	arbitrary data to sign

Returns:

Type:: xdr.DecoratedSignature

the raw signature structure which can be added directly to a transaction envelope

signPayloadDecorated(data) → {xdr.DecoratedSignature}

Returns the raw decorated signature (hint+sig) for a signed payload signer.

The hint is defined as the last 4 bytes of the signer key XORed with last 4 bytes of the payload (zero-left-padded if necessary).

Source:

js-stellar-base/src/keypair.js, line 261

See:

https://github.com/stellar/stellar-protocol/blob/master/core/cap-0040.md#signature-hint
TransactionBase.addDecoratedSignature

Parameters:

Name	Type	Description
`data`	`Buffer`	data to both sign and treat as the payload

Returns:

Type:: xdr.DecoratedSignature

verify(data, signature) → {boolean}

Verifies if signature for data is valid.

Source:

js-stellar-base/src/keypair.js, line 229

Parameters:

Name	Type	Description
`data`	`Buffer`	Signed data
`signature`	`Buffer`	Signature

Returns:

Type:: boolean

xdrMuxedAccount(idopt) → {xdr.MuxedAccount}

Creates a xdr.MuxedAccount object from the public key.

You will get a different type of muxed account depending on whether or not you pass an ID.

Source:

js-stellar-base/src/keypair.js, line 139

Parameters:

Name	Type	Attributes	Description
`id`	`string`	<optional>	stringified integer indicating the underlying muxed ID of the new account object

Returns:

Type:: xdr.MuxedAccount

(static) fromPublicKey(publicKey) → {Keypair}

Creates a new Keypair object from public key.

Source:

js-stellar-base/src/keypair.js, line 103

Parameters:

Name	Type	Description
`publicKey`	`string`	public key (ex. `GB3KJPLFUYN5VL6R3GU3EGCGVCKFDSD7BEDX42HWG5BWFKB3KQGJJRMA`)

Returns:

Type:: Keypair

(static) fromRawEd25519Seed(rawSeed) → {Keypair}

Creates a new Keypair object from ed25519 secret key seed raw bytes.

Source:

js-stellar-base/src/keypair.js, line 79

Parameters:

Name	Type	Description
`rawSeed`	`Buffer`	Raw 32-byte ed25519 secret key seed

Returns:

Type:: Keypair

(static) fromSecret(secret) → {Keypair}

Creates a new Keypair instance from secret. This can either be secret key or secret seed depending on underlying public-key signature system. Currently Keypair only supports ed25519.
