If official information is declassified,如果官方資訊被解密declassified， it used to be secret它原本是機密 — stamped, locked, only for certain people —──蓋了章、鎖起來、只有特定人能看── and now the government (or the army, or the agency)而現在政府（或軍方、或機關） has taken that secret status off.把那個機密身份拿掉了。 The papers, photos, or files這些文件、照片或檔案 can be shown, published, or requested可以被公開、出版，或申請調閱 in a way they could not before.用之前不行的方式。

People say “declassified documents,” “a declassified report,” “the files were declassified after thirty years.” It is almost always about state or institutional secrets, not about your diary or a company’s ordinary files (those are more often confidential, then released).

Though actually, news stories love the word, so you will also hear it a little loosely for anything that “comes out of the dark.” Strictly, declassified means it was classified first. That is different from unclassified, which can mean it was never secret to begin with.
