青字はPrescriptionDocument なので Decodeすれば 処方CSVが出てくるはずです。

PrescriptionSign 以降が 電子署名部分と考えられますが,

赤字の部分が電子署名の暗号部分なので, ここをBase64Decodeしてみると, 大部分は判読不能です。テキストエンコーディングが不適なのでしょうか? ,ただ, この部分をブラウザーで読ませて, テキストエンコーディングをいくつか変えてみても判読不能のままです。一部に読める文字列が認められます。おそらく, abcd病院, 医師 何野 太郎,  日付・時刻というようなことが 英字と日本語で書いてあるんでしょう。これはES-XLと考えられます。
