The scrypt key derivation function and encryption utility. A simple password-based encryption utility is available as a demonstration of the scrypt key derivation function.
On modern hardware and with default parameters, the cost of cracking the password on a file encrypted by scrypt enc is approximately 100 billion times more than the cost of cracking the same password on a file encrypted by openssl enc; this means that a five-character password using scrypt is stronger than a ten-character password using openssl. The scrypt utility can be invoked as scrypt enc infile [outfile] to encrypt data (if outfile is not specified, the encrypted data is written to the standard output), or as scrypt dec infile [outfile] to decrypt data (if outfile is not specified, the decrypted data is written to the standard output). scrypt also supports three command-line options: If the encrypted data is corrupt, scrypt dec will exit with a non-zero status.

Although iTerm works quite nicely out of the box, there are a few unix shell-specific tweaks you can implement that help to take advantage of some of the many nice features.
In what follows, I describe and give some examples of a few customizations. iTerm Tab, Title Bar and $DISPLAY Customizations I have been using iTerm instead of Apple's Terminal.app for several years. One of the main advantages of this over the Terminal.app that comes with OS X is the tabbed window feature. It has many other features that I also like, including selection to copy text, middle-button-paste, transparency, bookmarks, etc. Home - FUSE for OS X. Form Follows Function. Wireshark · Go deep.
