Function fingerprint

fingerprint(key: Uint8Array): Promise<string>
Computes the OpenSSH SHA-256 fingerprint of a raw SSH key blob.

This is the SHA256:... form that ssh-keygen -l prints and that servers advertise for host-key pinning: the base64 (standard alphabet, no = padding) of the SHA-256 digest of the wire-encoded key. Pass the raw key bytes a HostKeyVerifier receives to derive a stable fingerprint to compare against a trusted value (trust-on-first-use, then pin).
Parameters
- key: Uint8Array
  The raw SSH key blob (the bytes handed to HostKeyVerifier.verify).
Returns Promise<string>
The fingerprint string, e.g. SHA256:n3b0K... (43 base64 chars after the prefix).
Since
1.0.4
Example
```
import { connect, fingerprint } from 'edgeport/ssh';

const session = await connect({
	hostname: 'box',
	username: 'u',
	password: pw,
	hostKey: {
		async verify(_type, key) {
			const fp = await fingerprint(key);
			return fp === trustedFingerprint; // pin against a stored value
		}
	}
});
```
