Hello Clemens,
I came across a potential use case for an encryption profile: electronic
tendering (in the context of public procurement in Europe). I'm told
encryption/decryption services would help solve many practical
interoperability issues in this domain. But there is a requirement (in some
countries) that the content can only be decrypted if all participating key
owners agree. This could be done by splitting the generated symmetric key
in parts, with the various parts encrypted using different keys. Could your
profile (be extended to) support this?
