I'm not sure if you're asking about the standards or the NSS implementations of the standards (there are multiple of each). PKCS#7 v 1.5, also known as Cryptographic Message Syntax (CMS), is RFC 2315. It was the first in a series of RFCs publishing various versions of CMS. It was used in S/MIME V 2, RFC 2311. It was succeeded by CMS 1 - RFC 2630 used in S/MIME v 3.0, RFC 2633 CMS 2 - RFC 3369 CMS 3 - RFC 3852, used in S/MIME v 3.1, RFC 3851. There was also an extension to CMS 1 known as ESS, RFC 2634. NSS contains two separate libraries that implement versions of CMS. The functions and typedefs whose names begin with SEC_PKCS7 embody an implementation of PKCS#7 v1.5. See a list in http://mxr.mozilla.org/security/search?string=SEC_PKCS7&find=nss.*h The functions whose names begin with NSS_CMS and the typedefs whose names begin with NSSCMS embody an implementation of CMS 1 http://mxr.mozilla.org/security/search?string=NSS_*CMS&find=nss.*h®exp=1 Today, Thunderbird (which implements S/MIME 3.0) uses the NSS_CMS functions. NSS internally still uses the older SEC_PKCS7 functions for decoding signedData messages, which are used to download certificate chains. http://developer.mozilla.org/En/NSS_Certificate_Download_Specification > Are there any specific examples present on its usage? For the SEC_PKCS7 API, there are examples in these files: http://mxr.mozilla.org/security/source/security/nss/cmd/p7content/p7content.c http://mxr.mozilla.org/security/source/security/nss/cmd/p7env/p7env.c http://mxr.mozilla.org/security/source/security/nss/cmd/p7sign/p7sign.c http://mxr.mozilla.org/security/source/security/nss/cmd/p7verify/p7verify.c http://mxr.mozilla.org/security/source/security/nss/cmd/signver/pk7print.c http://mxr.mozilla.org/security/source/security/nss/cmd/signver/signver.c For the NSS_CMS API, see http://mxr.mozilla.org/security/source/security/nss/cmd/smimetools/cmsutil.c > Thanks _______________________________________________ dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
