An ECDSA signature, generated by the ECDSA.sign function. You can get the DER encoded signature via the der property, or the r,s,v form via the r, s and v properties.

Constructors

new EcdsaSignature()

new EcdsaSignature(r, s, v, DERencoding): EcdsaSignature

Parameters

• r: Uint8Array<ArrayBufferLike>

The r component of the signature (32 bytes)

• s: Uint8Array<ArrayBufferLike>

The s component of the signature (32 bytes)

• v: number

The v component of the signature (integer, with possible values 27/28/29/30)

• DERencoding: Uint8Array<ArrayBufferLike>

Returns

EcdsaSignature

A new EcdsaSignature object

Throws

If the r, s or v values are invalid.
