The only error which will occur in practice is if the .Fa cms type is invalid. .Sh SEE ALSO .Xr CMS_ContentInfo_new 3 , .Xr CMS_encrypt 3 , .Xr CMS_final 3 , .Xr CMS_sign 3 , .Xr ERR_get_error 3 .Sh STANDARDS RFC 5652: Cryptographic Message Syntax .Bl -dash -compact -offset indent .It section 5.1: SignedData Type .It section 6.1: EnvelopedData Type .El .Sh HISTORY .Fn CMS_add0_cert , .Fn CMS_add1_cert , .Fn CMS_get1_certs , .Fn CMS_add0_crl , and .Fn CMS_get1_crls first appeared in OpenSSL 0.9.8h and .Fn CMS_add1_crl in OpenSSL 1.0.0.
