.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a small shell script for managing encrypted files.
|
||||
It leverages
|
||||
.Xr gpg2 1
|
||||
to create and read encrypted files,
|
||||
and can generate random data to populate them.
|
||||
.Pp
|
||||
Because of this,
|
||||
.Nm
|
||||
can be used as an account credentials manager,
|
||||
or as a general-purpose key-value store of encrypted information.
|
||||
.Bl -tag -width Ds
|
||||
.It Nm Cm add Ar key Op Ar value ...
|
||||
Adds a value to
|
||||
.Ar key .
|
||||
.Ar value
|
||||
is inserted as is, without any extra modifications.
|
||||
If no
|
||||
.Ar value
|
||||
is specified on command line,
|
||||
.Cm add
|
||||
will read the value from standard input.
|
||||
.Cm add
|
||||
will fail if
|
||||
.Ar key
|
||||
already has a value.
|
||||
.It Nm Cm gen Oo Fl l Ar length Oc Op Ar chars
|
||||
Outputs a randomly generated sequence.
|
||||
The generated sequence consist of characters
|
||||
.Ar chars .
|
||||
Defaults to
|
||||
.Ar +/0-9A-Za-z .
|
||||
If
|
||||
.Fl l Ar length
|
||||
is provided, the randomly generated sequence will be
|
||||
.Ar length
|
||||
characters long.
|
||||
Defaults to 43.
|
||||
.It Nm Cm get Ar key
|
||||
Decrypts the value associated with
|
||||
.Ar key
|
||||
and prints it to standard output.
|
||||
Fails if
|
||||
.Ar key
|
||||
doesn't have a value associated with it.
|
||||
.It Nm Cm has Ar key
|
||||
Returns success if
|
||||
.Ar key
|
||||
has a value associated with it.
|
||||
Fails otherwise.
|
||||
.It Nm Cm ls Op Ar keys ...
|
||||
For each
|
||||
.Ar key
|
||||
given as argument,
|
||||
list all the registered keys under that hierarchy.
|
||||
If no
|
||||

|
||||
is given, list all the registeres keys.

To use
|

.Nm
|

sekrit add accounts/example.com/user myuser
|
||||
sekrit gen accounts/example.com/pass
|

|
||||
Then, to retrieve credentials to login as
|
||||
.Ar myuser
|
||||
in
|
||||
.Ar example.com
|
||||
you can run
|
||||
.Bd -literal -offset indent
|

|

# sekrit is a relatively small shell script for writing and reading
|
||||
# encrypted files, aimed to deal mostly with accounts credentials, but
|
||||
# general enough to deal with any content. It can populate each key
|
||||
# with random data or with fixed data, reading either command-line
|
||||
# arguments or stdin.
|
||||
#
|
||||
# To be used as a password manager, it's recommended to pair it with
|
||||
# xclip(1). For example, for username, password and optional second
|
||||
# factor:
|
||||
#
|
||||
# sekrit get account/user | xclip -r -l 1 -sel clip -q
|
||||
# sekrit get account/pass | xclip -r -l 1 -sel clip -q
|
||||
# sekrit has account/2fa && sekrit get account/2fa \
|
||||
# | $program_for_totp | xclip -r -l 1 -sel clip -q
