I have very large globs of on the fly generated data that are to be signed and output as a base64 payload followed by a separate PKCS#7 package with a detached signature at the end of the transmission.
I’d like to avoid CMS_sign/CMS_final having to rely on a BIO_s_mem(), disk-storage or similar.
But rather simply do something like calculating the SHA256 as the payload is streamed out. And then have a CMS_sign/final do the deed with that SHA256 rather than a BIO.
Is there a way to use these interfaces (or ex) that way ?
With kind regards,
