It's similar to .p7c in that it uses the SignedData structure. From RFC5652... SignedData ::= SEQUENCE { version CMSVersion, digestAlgorithms DigestAlgorithmIdentifiers, encapContentInfo EncapsulatedContentInfo, certificates [0] IMPLICIT CertificateSet OPTIONAL, crls [1] IMPLICIT RevocationInfoChoices OPTIONAL, signerInfos SignerInfos } A .p7c is a SignedData structure that contains one or more "certificates", but nothing useful in "encapContentInfo" or "signerInfos". What we're proposing is a SignedData structure that contains zero or more "certificates" (CA certificates only), the TBSCertificate in "encapContentInfo" and a signature from the CA in "signerInfos". We'll need to define a new ContentType OID that means "TBSCertificate". > Russ > >> We (the 6962-bis editors) would like to propose that we replace the existing precertificate formats with a TBSCertificate wrapped in PKCS#7. This lays to rest, we think, any possible confusion with X509v3 certs, whilst allowing a simple mapping between the final cert and the pre-cert. >> >> Obviously there are details to be nailed down, but before we do so, we'd like to hear any discussion on the general idea. > > _______________________________________________ > Trans mailing list > Trans@ietf.org > https://www.ietf.org/mailman/listinfo/trans > -- Rob Stradling Senior Research & Development Scientist COMODO - Creating Trust Online Office Tel: +44.(0)1274.730505 Office Fax: +44.(0)1274.730909 www.comodo.com COMODO CA Limited, Registered in England No. 04058690 Registered Office: 3rd Floor, 26 Office Village, Exchange Quay, Trafford Road, Salford, Manchester M5 3EQ This e-mail and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
