What is a...
1) smime.p7s file?
2) PKCS #7 Signature file?
Got these as an email attatchment and just don't know what they are or what purpose they serve...
Thanks,

I received an e-mail with an attachment named smime.p7s (or smime.p7m). What is it?
The e-mail was signed or encrypted. But your e-mail program (e.g. webmail) does not support secure e-mail.
If it is a signed e-mail, the digital signature is displayed as a file attachment (smime.p7s). The content of the message is still visible. But you cannot verify the authenticity of the signature.
If it is an encrypted e-mail, the content is displayed as a file attachment (smime.p7m). You cannot decrypt the e-mail and view its content.
