From: Jameson Graef Rollins Date: Tue, 17 Feb 2009 01:15:58 +0000 (-0500) Subject: Stop all creation of a ssh_host_rsa_key.pub. Use openpgp2ssh to get X-Git-Tag: monkeysphere_0.23~89 X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=0c874fdd6abfa4b74d7805f2d2d121f08211b4aa;p=monkeysphere.git Stop all creation of a ssh_host_rsa_key.pub. Use openpgp2ssh to get the fingerprint from the host pgp public key. Prevents us from having to maintain the ssh pub key file, and generally makes things simpler. Also allows us to go back to having import_key take the key on stdin (which dkg will like). --- diff --git a/src/monkeysphere-host b/src/monkeysphere-host index d6e4c68..64023e0 100755 --- a/src/monkeysphere-host +++ b/src/monkeysphere-host @@ -37,8 +37,7 @@ MHTMPDIR="${MHDATADIR}/tmp" export MHTMPDIR # host pub key files -HOST_KEY_PUB="${SYSDATADIR}/ssh_host_rsa_key.pub" -HOST_KEY_PUB_GPG="${SYSDATADIR}/ssh_host_rsa_key.pub.gpg" +HOST_KEY_FILE="${SYSDATADIR}/ssh_host_rsa_key.pub.gpg" # UTC date in ISO 8601 format if needed DATE=$(date -u '+%FT%T') @@ -95,17 +94,12 @@ gpg_host_edit() { "0x${HOST_FINGERPRINT}!"
