NAME

       agent-transfer - copy a secret key from gpg-agent to ssh-agent

SYNOPSIS

       agent-transfer [options] KEYGRIP [COMMENT]

DESCRIPTION

       agent-transfer  extracts a secret key from a modern version of GnuPG agent and sends it to
       the running SSH agent.  This is useful for people whose keys are managed in the  long-term
       by GnuPG's gpg-agent, but who prefer the semantics of OpenSSH's ssh-agent for regular use.

       agent-transfer was written as part of the monkeysphere project.

       The KEYGRIP should be specified as a sequence of 20 hexadecimal characters.  If you aren't
       sure of the keygrip, you can inspect the output of:

               gpg --with-keygrip --list-secret-keys

       The COMMENT is optional, and will be stored alongside the key in ssh-agent.  It  must  not
       start with a -, to avoid being mistaken for an option.

OPTIONS

       agent-transfer  also  accepts  options  that  would  normally  be  passed to ssh-add(1) to
       constrain the use of the transferred key:

       -c     Indicates that added identities should be subject to confirmation before being used
              for authentication.

       -t SECONDS
              Indicates that the key should have a lifetime of SECONDS in the running ssh-agent.

FILES

       ~/.gnupg/S.gpg-agent
              The  socket where gpg-agent is listening.  This is the "standard socket" for modern
              GnuPG.

ENVIRONMENT VARIABLES

       GNUPGHOME
              The GnuPG home directory, where the standard socket for gpg-agent lives.   If  this
              is not set, it is assumed to be ~/.gnupg.

       SSH_AUTH_SOCK
              Specifies the location where the running ssh-agent is present.

       Several  other environment variables are also passed in some form to the gpg-agent to help
       it figure  out  how  to  run  a  sensible  pinentry,  including  GPG_TTY,  TERM,  DISPLAY,
       XAUTHORITY, GTK_IM_MODULE, DBUS_SESSION_BUS_ADDRESS, and LANG.

BUGS

       agent-transfer  can  only work with RSA and Ed25519 keys.  Support for other key types not
       yet implemented.  Patches welcome!
