Generate ECDSA Signature

Signs data using an Elliptic Curve Digital Signature Algorithm (ECDSA) private key.

In the diagram below, the dark rectangle represents the activity of signing some data using a private key that is stored at a safe location.

Also see: Create ECDSA Keys, Verify ECDSA Signature.


Properties

Private key

The private ECDSA key to use to generate the signed data (see Create ECDSA Keys). The key can be given as a list of bytes or a base64 string.

Hash algorithm

The hash algorithm to use when signing the data.

Options:

Data

The data to sign. This can be a list of bytes or a base64 string.


Definition

The ECDSA signature in the form of a list of bytes.


Example

A simple usage scenario is where the private key is retrieved from a local database and used to sign some data which is received as input.
