Re: [openpgp] ECDH and ELG-E primary keys

2014-08-04 12:08:37
I'm not so sure I would say "no software" can use them. They're odd in that
they're a bare Public-Key Packet, but that doesn't mean they're unusable.

For example, the first example is a secp256r1 public key for ECDH with
point 
54913208749856979301715917236679182042233113041563426424642991739197245983353452579573506780881803740193710199307901035821397170740305648420195074480633099
and SHA256 and 128 bit AES for KDF, as described in RFC6637.

There may exist software that is using the OpenPGP format for exchanging
keys without generating what most software would expect.

what software can use them?)

No software can use those keys becuase they are not capabable of
signing.  They are rejected ("no user Id" because the self-signature
does not check out).
