    Default Evoultion encrption error

    I have created my keys, I have tried through both the CLI and Seahorse.

    When I sign an email I get the following error:
    Code:
    Could not create message
    Because "gpg: writing to `-'
    gpg: DSA key AC806A0E requires a 256 bit or larger hash
    gpg: signing failed: General error
    ", you may need to select different mail options.
    Code:
    # gpg --version
    gpg (GnuPG) 2.0.12
    libgcrypt 1.4.4

    keyserver  hkp://keys.gnupg.net
    personal-digest-preferences SHA256
    cert-digest-algo SHA256
    I added the digest lines in an effort to trouble shoot the issue. The error use to say "224 bit or larger hash"

    Default Re: Evoultion encrption error

    well... I Found the answer https://bugzilla.gnome.org/show_bug.cgi?id=304415

    I will have to see if this impacts the servers that run SLED.

    For the workaround you have to use old and less secure SHA1

    Code:
    # egrep -v '^#' gpg.conf | egrep -v '^$'
    require-cross-certification
    keyserver  hkp://keys.gnupg.net
    personal-digest-preferences SHA1
    cert-digest-algo SHA1
