For example if multiple signers or non default digest +algorithms are needed. New attributes can also be added using the returned +CMS_SignerInfo structure and the \s-1CMS\s0 attribute utility functions or the +\&\s-1CMS\s0 signed receipt request functions. +.PP +Any of the following flags (ored together) can be passed in the \fBflags\fR +parameter. +.PP +If \fB\s-1CMS_REUSE_DIGEST\s0\fR is set then an attempt is made to copy the content +digest value from the CMS_ContentInfo structure: to add a signer to an existing +structure. An error occurs if a matching digest value cannot be found to copy. +The returned CMS_ContentInfo structure will be valid and finalized when this +flag is set. +.PP +If \fB\s-1CMS_PARTIAL\s0\fR is set in addition to \fB\s-1CMS_REUSE_DIGEST\s0\fR then the +CMS_SignerInfo structure will not be finalized so additional attributes +can be added. In this case an explicit call to \fICMS_SignerInfo_sign()\fR is +needed to finalize it. +.PP +If \fB\s-1CMS_NOCERTS\s0\fR is set the signer's certificate will not be included in the +CMS_ContentInfo structure, the signer's certificate must still be supplied in +the \fBsigncert\fR parameter though. This can reduce the size of the signature if +the signers certificate can be obtained by other means: for example a +previously signed message. +.PP +The SignedData structure includes several \s-1CMS\s0 signedAttributes including the +signing time, the \s-1CMS\s0 content type and the supported list of ciphers in an +SMIMECapabilities attribute. If \fB\s-1CMS_NOATTR\s0\fR is set then no signedAttributes +will be used. If \fB\s-1CMS_NOSMIMECAP\s0\fR is set then just the SMIMECapabilities are +omitted. +.PP +OpenSSL will by default identify signing certificates using issuer name +and serial number. If \fB\s-1CMS_USE_KEYID\s0\fR is set it will use the subject key +identifier value instead. An error occurs if the signing certificate does not +have a subject key identifier extension. +.PP +If present the SMIMECapabilities attribute indicates support for the following +algorithms in preference order: 256 bit \s-1AES\s0, Gost R3411\-94, Gost 28147\-89, 192 +bit \s-1AES\s0, 128 bit \s-1AES\s0, triple \s-1DES\s0, 128 bit \s-1RC2\s0, 64 bit \s-1RC2\s0, \s-1DES\s0 and 40 bit \s-1RC2\s0. +If any of these algorithms is not available then it will not be included: for example the \s-1GOST\s0 algorithms will not be included if the \s-1GOST\s0 \s-1ENGINE\s0 is +not loaded. +.PP +\&\fICMS_add1_signer()\fR returns an internal pointer to the CMS_SignerInfo +structure just added, this can be used to set additional attributes +before it is finalized. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fICMS_add1_signer()\fR returns an internal pointer to the CMS_SignerInfo +structure just added or \s-1NULL\s0 if an error occurs. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fIERR_get_error\fR\|(3), \fICMS_sign\fR\|(3), +\&\fICMS_final\fR\|(3), +.SH "HISTORY" +.IX Header "HISTORY" +\&\fICMS_add1_signer()\fR was added to OpenSSL 0.9.8 |
