Function: char * crypt (const char *key, const char *salt)

The crypt function takes a password, key, as a string, and a salt character array which is described below, and returns a printable ASCII string which starts with another salt. It is believed that, given the output of the function, the best way to find a key that will produce that output is to guess values of key until the original value of key is found.

The salt parameter does two things. Firstly, it selects which algorithm is used, the MD5-based one or the DES-based one. Secondly, it makes life harder for someone trying to guess passwords against a file containing many passwords; without a salt, an intruder can make a guess, run crypt on it once, and compare the result with all the passwords. With a salt, the intruder must run crypt once for each different salt.

For the MD5-based algorithm, the salt should consist of the string $1$, followed by up to 8 characters, terminated by either another $ or the end of the string. The result of crypt will be the salt, followed by a $ if the salt didn't end with one, followed by 22 characters from the alphabet ./0-9A-Za-z, up to 34 characters total. Every character in the key is significant.

For the DES-based algorithm, the salt should consist of two characters from the alphabet ./0-9A-Za-z, and the result of crypt will be those two characters followed by 11 more from the same alphabet, 13 in total. Only the first 8 characters in the key are significant.

After running

firefox -ProfileManager

and creating several different profiles, use this command to run multiple Firefox profiles simultaneously.

The above command will:

- open a Remote Desktop connection to [servername / IP Address],

- authenticate using [username] and [password],

- configure resolution to best fit your desktop (I have a 1366x768px resolution so I left space for 2 panels of 22px each),

- sets the color depth for the connection to 16 bpp,

- hides the window manager decorations,

- enables compression of the RDP data stream,

- enables persistent bitmap caching.

ffmpeg

-i = input file name

-s = set frame size, qcif=176x144

-vcodec = force video codec

-r = frame-rate [default = 25]

-b = bit-rate [200 kb/s]

-acodec = force audio codec

-ab = audio bitrate in bits/s [64k]

-ac = no. of audio channels [1]

-ar = audio sampling frequency [44100 Hz]

optional:

-sameq = use same video quality as source (implies VBR)

-f = force format

-y = overwrite output files
