I recently created a new Curve 25519 encryption subkey. One of the other PGPNET members tells me GnuPG 2.1.12 reports the subkey size as 0 and will not encrypt to this subkey,instead giving the error:- gpg: pubkey_encrypt failed: Provided object is too short gpg: test: encryption failed: Provided object is too short I get that error using GnuPG 2.1.11 but not 2.1.12 (and I do not see a key size for an ECC key in my key listing). Any ideas why he cannot encrypt to this Curve 25519 encryption subkey? (Subkey 0xA11C7EE5DA49DC12 on main key 0x251BCCEB547B7194) He is running OpenSUSE 13.2, which does not provide GnuPG 2.1 in their standard repos so he installed it from an alternative repo [0]. This install also replaces a number of related packages to resolve dependencies. He has provided the following information about the GnuPG and Libgcrypt packages he has installed:- Information for package gpg2: - ----------------------------- Repository: openSUSE-13.2-Security-Privacy Name: gpg2 Version: 2.1.12-164.1 Arch: i586 Vendor: obs://build.opensuse.org/security:privacy Installed: Yes Status: up-to-date Installed Size: 5.5 MiB Summary: GnuPG 2 Description: GnuPG 2 is the successor of "GnuPG" or GPG.
