Post #1 of 9 (7506 views) Permalink Error with encrypting: unusable public key Hi all,

Gpg Batch Unusable Public Key

I keep getting an error trying to encrypt to the key gpg: no valid addressees 0xCC21E10F. The key is self-signed, gpg --check-sigs does not complain, but still when I try to encrypt gpg trust public key I get: gpg: 0xCC21E10F: skipped: unusable public key I am using gpg 1.4.5 on a Linux box (SuSE 10.2). Could this be a matter of algorithms? The key https://lists.gnupg.org/pipermail/gnupg-users/2006-March/028216.html is available on the keyservers. Thanks for help, Olaf -- Dipl.Inform.

So this is one of the "sign only" keys and to enable encryption, one would add an encryption only subkey? Olaf -- Dipl.Inform.

But now with SuSE 8.1 i got the following error message when trying to encrypt a message with a fully trustet gpg key: gpg:warning:using unsecure memory gpg:please see www.gnupg.org/faq.html for more details gpg::skipped:unusable public key gpg:[stdin]:sign and encrypt fails: unusable public key encryption fails even if there is no signing expected. btw, is there no possibility to mark and copy error messages like this in kde? thx for a great work using gpg in kmail! regards, joerg maier Comment 1 J 2002-12-17 13:44:46 UTC using gpg from bash interface works proper with these keys! updated gpg to version 1.2.1, but that made no changes to error messages. didnt find any updates for kdenetwork. Comment 2 Ingo Klöcker 2002-12-17 15:28:47 UTC Did you mark your own key as ultimately trusted? Since GnuPG 1.0.7 this is necessary. Comment 3 J 2002-12-17 16:19:01 UTC yes, even my key is marked as ultimately trusted. reason for the error message seems to be the public key used for encryption. i tried several public keys like gpg and pgp keys. thanx, joerg maier Comment 4 J 2003-01-01 20:47:59 UTC Sorry for sending this bug, it is no bug! My own secret key was expired. i created a new and now it works. strange is that in command-line-interface of gpg, it worked even with expired secrets. the error message is strange, too, because in my op, it was the secret key who preserved kmail to ecrypt messages... Comment 5 Ingo Klöcker 2003-01-02 15:58:45 UTC Subject: Re: gpg: skipped: unusable public key Thanks for the update. As it wasn't a bug in KMail I close the report. Comment 6 J 2003-01-02 16:31:26 UTC The only Bug ist the misleading error Message! Shouldnt it say my Private key is expired? And why it is possible to sign messages with a expired key and it is not possible to encrypt a message when the key for encryption is ok?
