Daniel Kahn Gillmor created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1185

## Description of the feature:

`certtool` currently supports creation of PKCS#7-style signatures.  It would be great if it could also offer PKCS#7-style encryption and decryption.  In its modern form, this is lumped under [Cryptographic Message Syntax](https://tools.ietf.org/html/rfc5652), and is used in S/MIME [EnvelopedData](https://tools.ietf.org/html/rfc8551#section-3.3) or [AuthEnvelopedData](https://tools.ietf.org/html/rfc8551#section-3.4) parts.

## Applications that this feature may be relevant to:

S/MIME e-mail and other messaging clients may use encryption to protect messages.

## Is this feature implemented in other libraries (and which)

`gpgsm` from the GnuPG project offers some flavors of CMS.  OpenSSL offers some as well, in particular the library functions `SMIME_{read,write}_{CMS,PKCS7}` and `{CMS,PKCS7}_{en,de}crypt`.
