Expand description

Meta-Helper fn: get a Sequoia PublicKey from an openpgp-card PublicKeyMaterial, timestamp and card-Fingerprint.

For ECC decryption keys, possible values for the parameters hash and sym will be tested. Once a key with matching fingerprint is found in this way, it is considered the correct key, and returned.

The Fingerprint of the retrieved PublicKey is always validated against the Fingerprint as stored on the card. If the fingerprints doesn’t match, an Error is returned.
