extractBytesFromKeyPairSigner

function extractBytesFromKeyPairSigner(keypairSigner): Promise<Uint8Array<ArrayBufferLike>>;

Extracts the raw key material from an extractable Ed25519 KeyPairSigner.

Parameters

Parameter	Type	Description
`keypairSigner`	`KeyPairSigner` \| `ExtractableKeyPairSigner`	An extractable Ed25519 `KeyPairSigner`

Promise<Uint8Array<ArrayBufferLike>>

Raw key bytes as Uint8Array

Requires a keypair generated with extractable=true. See generateExtractableKeyPairSigner.
The extracted bytes can be used to reconstruct the CryptoKeyPair with createKeyPairSignerFromBytes.
