# userSMIMECertificate

PKCS#7 SignedData, where the content signed is ignored by consumers of `userSMIMECertificate` values. PKCS#7 is described in [RFC 2315](https://www.rfc-editor.org/rfc/rfc2315.html) .

A value holds the entire certificate chain and a `smimeCapabilities` field as described in [RFC 2633](https://www.rfc-editor.org/rfc/rfc2633.html) . This attribute is preferred over `userCertificate` for S/MIME applications.

Values should have a data `contentType` and omit the `content` field.

Request and transfer values using the binary option for the attribute description, `userSMIMECertificate;binary`.
