srd is a secure rolodesk, which is a bit of a retro name for an encrypted set of notes. In modern parlance, it might be called a password vault, but the idea is to be able to write and retrieve arbitrary bits of text.
I developed srd on an ubuntu linux system. There's no real reason to suspect it wouldn't work elsewhere, but that hasn't been tested.
There's a library if you want to use the code in another context with minimal hacking.
srd changed file format in May 2015. See below if this affects you. You will know it affects you because you can't read your srd files anymore.
The code is stable, and I believe it works. There are reasonably extensive regtests that convince me of this. I use it and trust my secrets (bank passwords, online account info, etc.) to it. Send me mail with feedback. As always (see src/COPYING), you accept that it may not work for you. If it doesn't, I'd appreciate hearing of a reproducible case of the failure.
I wrote a short python script once upon a time to do something similar. I developed a bunch of features I wanted to add. It became a rewrite. As an exercise, I decided to see how much longer it would take to write it in C++ rather than python. (Answer: about five times longer.) And it amuses me. And it pushes me to look at some new libraries and language features that I don't get to use at work.
The other answer, since there's no shortage of password vaults out there, is that (1) I wanted something that lives nicely on the commandline, and (2) I wanted to understand the code so that I'm sure it's doing what I want. Those could probably both have been satisfied more easily without writing code, but would have left me less happy.
srd <options> [key-match-pattern]
Pattern matching options (-m, -D, -d) may be repeated.
Multiple key patterns (-m) match as inclusive or.
Multiple payload patterns (-d) match as and (but cf. -J).
Multiple key-or-payload patterns (-D) match as inclusive or.
Key-match-pattern, if present, is the same as specifying -m.
To create a new record, use -e with no pattern.
Allowed options:
General options:
-h [ --help ] Produce help message
-R [ --read-only ] Read-only, do not persist data
--database-dir arg Name of directory to use for database instead of
default
-v [ --verbose ] Emit debugging information
Actions (if none, then match):
-e [ --edit ] Edit record
-x [ --delete ] Delete the results of an (exact) key match.
Conceptually -E -m arg, can be used with -mDd.
-X [ --delete-all ] Delete all matches. Conceptually equivalent to -m arg,
can be used with -mDd. If more than one match, will
request confirmation.
-p [ --passwd ] Change password (no other options permitted)
--create Create database. The database is identified by a hash
of the password, so --create distinguishes between
creating a new database and mistyping the password.
--import arg Import a text file. The format is the same as that
output by -f: each line must either be "[KEY]" for key
KEY or else begin with two spaces of indent (which are
disgarded during the input) for data (payload) portion
associated with the most recent key line.
-V [ --validate ] Confirm that all records are loadable and consistent
--checksum Compute database checksum (keys and payload)
--checksum-by-key Compute database checksum by key, restrictable by
matching options
Matching options:
-m [ --match-key ] arg Restrict to records whose keys match
-D [ --match-data-or-key ] arg Restrict to records whose key or data match
-d [ --match-data ] arg Restrict to records whose data match all
patterns (cf. -J)
-E [ --exact-match ] Exact key match
-i [ --ignore-case ] Match without case. (Does not affect
-g,--grep.)
-J [ --disjunction ] When matching multiple patterns against
payloads with -d, --match-data, use inclusive
or (any hit is sufficient)
Display options:
-k [ --keys-only ] Display keys only (default true if multiple matches,
false for single match)
-f [ --full-display ] Display full data (default true for single match,
false for multiple matches)
-g [ --grep ] arg Output filter for data
Test options (don't use outside regression tests):
-T [ --TEST ] arg Test mode, use local data directory, specify password
on commandline
The code may not be thread-safe. Indeed, it assumes a single event stream, where it is impossible, say, to edit two leaves at the same time. (The conflict here is at the level of the root, since each editor risks re-persisting the root differently.) There are some checks to avoid this happening, but no regtests rigorously confirm that this always works. Peer review and suggestions welcome. Cf. issues #26, #27 (both closed).
If you began using srd before 2 May 2015, you used a file format based on Boost serialization. For several reasons, this caused problems. As a result, srd switched to using Google protobufs.
In the unlikely event you began using srd before the file format
change, you'll need to recover the conversion version of srd from
github. It is on branch convert_to_protobuf
. README.md on that
branch explains how to convert. After conversion, it is best to
switch back to the modern production version (branch master).
