method

): Promise<ArrayBuffer>;

Using the method and parameters given by algorithm and the keying material provided by key, subtle.sign() attempts to generate a cryptographic signature of data. If successful, the returned promise is resolved with an <ArrayBuffer> containing the generated signature.

The algorithms currently supported include:

'RSASSA-PKCS1-v1_5'
'RSA-PSS'
'ECDSA'
'Ed25519'
'Ed448'
'HMAC'

class ArrayBuffer

Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

readonly [Symbol.toStringTag]: string
readonly byteLength: number
Read-only. The length of the ArrayBuffer (in bytes).
resize(
newByteLength?: number
): void;
Resizes the ArrayBuffer to the specified size (in bytes).
MDN
resize(
byteLength: number
): ArrayBuffer;
Resize an ArrayBuffer in-place.
slice(
begin: number,
end?: number
): ArrayBuffer;
Returns a section of an ArrayBuffer.
transfer(
newByteLength?: number
): ArrayBuffer;
Creates a new ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
MDN
transferToFixedLength(
newByteLength?: number
): ArrayBuffer;
Creates a new non-resizable ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
