SYNOPSIS

10       agent-transfer [options] KEYGRIP [COMMENT]
11
12

DESCRIPTION

14       agent-transfer  extracts  a  secret  key from a modern version of GnuPG
15       agent and sends it to the running SSH agent.  This is useful for people
16       whose  keys  are managed in the long-term by GnuPG's gpg-agent, but who
17       prefer the semantics of OpenSSH's ssh-agent for regular use.
18
19       agent-transfer was written as part of the monkeysphere project.
20
21       The KEYGRIP should be specified as a sequence of 20 hexadecimal charac‐
22       ters.   If  you  aren't sure of the keygrip, you can inspect the output
23       of:
24
25               gpg --with-keygrip --list-secret-keys
26
27       The COMMENT is optional, and will be stored alongside the key  in  ssh-
28       agent.   It  must  not  start  with a -, to avoid being mistaken for an
29       option.

OPTIONS

33       agent-transfer also accepts options that would normally  be  passed  to
34       ssh-add(1) to constrain the use of the transferred key:
35
36
37       -c     Indicates  that  added identities should be subject to confirma‐
38              tion before being used for authentication.
39
40
41       -t SECONDS
42              Indicates that the key should have a lifetime of SECONDS in  the
43              running ssh-agent.
44
45

FILES

47       ~/.gnupg/S.gpg-agent
48              The  socket where gpg-agent is listening.  This is the "standard
49              socket" for modern GnuPG.
50
51

ENVIRONMENT VARIABLES

53       GNUPGHOME
54              The  GnuPG  home  directory,  where  the  standard  socket   for
55              gpg-agent  lives.   If  this  is  not  set,  it is assumed to be
56              ~/.gnupg.
57
58
59       SSH_AUTH_SOCK
60              Specifies the location where the running ssh-agent is present.
61
62
63
64       Several other environment variables are also passed in some form to the
65       gpg-agent to help it figure out how to run a sensible pinentry, includ‐
66       ing  GPG_TTY,  TERM,  DISPLAY,  XAUTHORITY,  GTK_IM_MODULE,   DBUS_SES‐
67       SION_BUS_ADDRESS, and LANG.
