Currently, the secrets retrieved using the retrieveKey method of the KeyClient are of the
type byte[]. (Attribute of the Key object).
But the public key, which is returned in a KeyInfo object, is being accessible as a string
(base64 encoded binary data).
This patch changes getter/setter of the publicKey attribute of the KeyInfo object to do
the conversion from base64 encoded string to byte[] and vice versa.
With this patch all the keys retrieved are of the type byte[].
Please review the attached patch.
