Hey folks,

Ok, here is a paste from my latest app's help output:

Code:

123 v1.0
--------

Usage: 123 [Options] <path>
This utility is for renaming files to a "unique" filename, and also save the
unique md5 hex of the filename(s) and the original name next to it in a file
(named files.123). This utility also has the ability to encrypt and decrypt
using Blowfish.
If a file named key.123 is located in the same dir as this application, it's
content is used as <key>.

[Options]
--reverse - Change from the md5hex mentioned in .123 to the
original filename.
--rename - Rename files aswell.
--encrypt[=]<key> - Encrypt the .123 file's content aswell using the <key>
provided.
--decrypt[=]<key> - Tells the application that the .123 file's content is
encrypted, and tries to decypt this first by using the
<key> provided.

-[-]c[=]<pattern> - Encrypt file(s).
-[-]d[=]<pattern> - Decrypt file(s).
--key[=]<key> - Used with --c and --d option.

--paranoid - Using this option it first encrypts the files before
doing md5hex on their names (this, if creating the .123
file). Otherwise (if option --reverse is used), this
will lastly decrypt the file(s).

Examples:

#1) 123 --rename . - This will create the files.123 file, and also rename
the files in the current directory.

#2) 123 --rename --reverse . - This will change the files back to their
original name. ("Undo" the above).

#3) 123 --rename --encrypt=secret_pass . - This will do as #1, but also
encrypt the "files.123"'s
content using "secret_pass" as
a key.

#4) 123 -c=*.zip --key=secret_pass . - This will encrypt all .zip files in
the current directory with the key
"secret_pass".
Note: Any 32 length filename is
----- ignored, aswell as "key.123"
and "files.123".

The basic idea behind lies with .sfv files, but here the filename is md5:ed and saved with the original filename in a file. So, if you dont wanna have your filenames widely open, you can use this tool.

Example: In the file "files.123" it looks like this:

Code:

dd18bf3a8e0a2a3e53e2661c7fb53534 = test.txt
8caba7d65b81501f3b65eca199c28ace = test.zip

And those files in the dir are renamed to that 32 character long name. Quite like sfv. Now, if you want, you can also encrypt the data within this files.123. So it can be like:

Code:

52616e646f6d4956f12680d253240eb119e309b986784830ca729c89d91
c8c39bc130829c5aae6be18b2e9c6d61a117cf83ab1c1c9453d7105656d
44c2ca4f0ef1ade7c74604fc20b6daef3f5b2deb61767c7f5fbda8524ca
3dfca05af73f4044ab4830fe7c46303

Natrually, you can also, encrypt the files themselfes if you want. Preferbably before you do all that md5 on them.

Code:

test.txt.3nc
test.zip.3nc

Would be nice to have some comments on this app. And, maybe some ideas. GUI? (shouldnt really have to be needed!)

Edit: Maybe AES is better... But, an easy change. Main app is done. Change of algorithm is easy.

Thanks,
Ace
