Re: OpenPGP-Card v3.3 - ECC Curve25519 supported?
Hello. I have one oif this new openPGP Cards v3.3 and yes, they are capable of nist / brainpool only. curve25519 is not supported. I use it only with RSA keys for compatiblity reasons. Not everybody uses ECC capable versions of GnuPG or other compatible openPGP software. The card itself works well. I use it for various authentication, signing and encryption purposes like Email, SSH and in combination with gpgsm.

Re: OpenPGP-Card v3.3 - ECC Curve25519 supported?
Hello Karel, I do not recommend buying it. There is a bug in case of someone trying to send you 3DES encrytped messages [1][2]. As well it is not really backward compatible and there is no real documentation how to fix this except of [3] However Documentation does not state curve25519 but Brainpool [4] (p 32). best regards Dirk [1] https://dev.gnupg.org/T3576 [2] https://wiki.gnupg.org/SmartCard#Known_Bug.28s.29_of_OpenPGPcard [3] https://lists.gnupg.org/pipermail/gnupg-users/2018-March/060074.html [4] https://gnupg.org/ftp/specs/OpenPGP-smart-card-application-3.3.pdf On 19.03.2018 18:57, karel-...@tutanota.com wrote: > Hello! > I have seen that the latest revision of OpenPGP-cards (3.3) supports > ECC-keys and is available for sale. > Does this also include curve25519 or "only" Brainpool and NIST? > Thanks for enlightment! > Karel > > > ___ > Gnupg-users mailing list > Gnupg-users@gnupg.org > http://lists.gnupg.org/mailman/listinfo/gnupg-users ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
OpenPGP-Card v3.3 - ECC Curve25519 supported?
Hello! I have seen that the latest revision of OpenPGP-cards (3.3) supports ECC-keys and is available for sale. Does this also include curve25519 or "only" Brainpool and NIST? Thanks for enlightment!
