{{note|Opaque signing|Opaque signing refers to the technique of embedding the text into the base64 encoded CMS (PKCS #7 based Cryptographic Message Syntax) object (content type: application/x-pkcs7-mime) of the signature, so it can only be read if the client supports S/MIME. Clear signing transmits the clear text and only appends the signature (content type: application/x-pkcs7-signature), which allows clients without S/MIME support to read the message.}}
