After that date, NIST will begin to deprecate current digital signature algorithms, meaning those algorithms will be considered insecure and will be unsupported.

Generally power of attorney consists of the giver and holder identity, the contents of the letter and the signatures of the parties. The signature was made by using a tool such as pen.
