PEM 格式憑證檔案

典型的 PEM 格式憑證檔案類似以下範例。

私密金鑰

私密金鑰可能會以不同的格式顯示，不過都會在明確的 BEGIN 與 END 標記內。

有效的 PEM 區段會以下列其中一個標記開始。 

-----BEGIN RSA PRIVATE KEY----- 
-----BEGIN PRIVATE KEY-----

加密私密金鑰會以下列其中一個標記開始。 

-----BEGIN ENCRYPTED PRIVATE KEY-----

Bag 屬性

Microsoft 憑證工具有時候會將 Bag 屬性新增到憑證檔案。VMware Aria Operations 能安全地略過 BEGIN 與 END 標記外的內容，包括 Bag 屬性區段。
