File Format Description

Email message that includes a digital signature; can be used for sending secure emails that can only be viewed by the intended recipient; verifies that the email is from who it claims to be from and that the email has not been modified in transit.

If an email program does not handle digital signatures, a P7S file may appear as an attachment (smime.p7s) to the email message.

NOTE: Email programs that use P7S files use PKCS (Public-Key Cryptography Standard) #7 to sign email messages.
