# Class: EcdsaPublicKey

An ECDSA public key, generated by the [ECDSA.keygen](/node/api-ref/classes/Ecdsa#keygen) function.
You can get the compressed form (33 bytes) via the `serializeCompressed` function,
or the uncompressed form (65 bytes) via the `serializeUncompressed` function.

## Constructors

### new EcdsaPublicKey()

> **new EcdsaPublicKey**(`pubkey`): [`EcdsaPublicKey`](/node/api-ref/classes/EcdsaPublicKey)

#### Parameters

• **pubkey**: `string` | `Uint8Array`

The uncompressed public key as a Uint8Array or a hex string. If the Uint8Array is 65 bytes long (SEC1 encoding), the first byte will be ignored.

A new EcdsaPublicKey object
