Hi everybody, I'm trying to use NSS for adding a new signer to a previously computed CMS signature, but i can't achieve that, and i have found examples nowhere.
The first signature is made with the call sequence : NSS_CMSMessage_Create / NSS_CMSSignedData_Create / NSS_CMSSignerInfo_Create / NSS_CMSMessage_GetContentInfo / NSS_CMSSignedData_GetContentInfo / NSS_CMSSignerInfo_Create / NSS_CMSEncoder_Start / NSS_CMSEncoder_Update / NSS_CMSEncoder_Finish. I thought maybe i can decode the first CMS data with NSS_CMSDecoder_* functions to retrieve a NSSCMSMessage structure, and then create a new signer info with NSS_CMSSignerInfo_Create, but i don't know what to do next (and how to trigger the cryptographic operations with the certificate). Maybe somebody has already done something like that... Thanks a lot. Nate. -- dev-tech-crypto mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-crypto
