#### 7.1.2.9 Precertificate Profile

A Precertificate is a signed data structure that can be submitted to a Certificate Transparency log, as defined by [RFC 6962](https://tools.ietf.org/doc/html/rfc6962). A Precertificate appears structurally identical to a Certificate, with the exception of a special critical poison extension in the `extensions` field, with the OID of `1.3.6.1.4.1.11129.2.4.3`. This extension ensures that the Precertificate will not be accepted as a Certificate by clients conforming to [RFC 5280](https://tools.ietf.org/doc/html/rfc5280). The existence of a signed Precertificate can be treated as evidence of a corresponding Certificate also existing, as the signature represents a binding committment by the CA that it may issue such a Certificate.

The existence of a signed Precertificate can be treated as evidence of a corresponding Certificate also existing, as the signature represents a binding commitment by the CA that it may issue such a Certificate.

A Precertificate is created after a CA has decided to issue a Certificate, but prior to the actual signing of the Certificate. The CA MAY construct and sign a Precertificate corresponding to the Certificate, for purposes of submitting to Certificate Transparency Logs. The CA MAY use the returned Signed Certificate Timestamps to then alter the Certificate's `extensions` field, adding a Signed Certificate Timestamp List, as defined in [Section 7.1.2.11.3](#712113-signed-certificate-timestamp-list) and as permitted by the relevant profile, prior to signing the Certificate.

Once a Precertificate is signed, relying parties are permitted to treat this as a binding committment from the CA of the intent to issue a corresponding Certificate, or more commonly, that a corresponding Certificate exists. A Certificate is said to be corresponding to a Precertificate based upon the value of the `tbsCertificate` contents, as transformed by the process defined in [RFC 6962, Section 3.2](https://tools.ietf.org/doc/html/rfc6962#section-3.2).

This profile describes the transformations that are permitted to a Certificate to construct a Precertificate. CAs MUST NOT issue a Precertificate unless they are willing to issue a corresponding Certificate, regardless of whether they have done so. Similarly, a CA MUST NOT issue a Precertificate unless the corresponding Certificate conforms to these Baseline Requirements, regardless of whether the CA signs the corresponding Certificate.
