- When you reopen the file, Vim will ask for the key; if you enter the wrong key, Vim will "decrypt" it to gibberish content. DO NOT SAVE such a gibberish buffer, or your data will be corrupted. While editing, the text in the swap file, undo file, and backup files are also encrypted; the text in memory is not encrypted. The viminfo file is also not encrypted, and thus should not be used: :set viminfo= If you want to disable encryption, just empty the key option: :set key= The difference between :X and :set key=something is that :X displays asterisks as you type, so that no one can peek at your encryption key. Also, :set commands may end up in your viminfo file. From version 7.3, Vim supports Blowfish encryption as well as the default pkzip-compatible method. Starting at 7.4.399, a new blowfish method is available to fix security problems in the original. Use one of the following to query or set the encryption method before writing the file: :setlocal cm? " show encryption method for the current file :setlocal cm=zip " weak (default for backwards-compatibility) :setlocal cm=blowfish " better :setlocal cm=blowfish2 " best (requires Vim version 7.4.399 or higher) cm is an abbreviation for cryptmethod. Pkzip is a weak encryption method, but is compatible with Vim 7.2 and older; Blowfish is strong, especially using the fixed "blowfish2" method. [help encryption] includes: The algorithm used is breakable. A 4 character key in about one hour, a 6 character key in one day (on a Pentium 133 PC). This requires that you know some text that must appear in the file. An expert can break it for any key. When the text has been decrypted, this also means that the key can be revealed, and other files encrypted with the same key can be decrypted. The blowfish method provides strong confidentiality, but no message integrity guarantees. It is known to be vulnerable to undetected modification if someone has write access to your files. If this is a concern, you should encrypt your file using an external program that supports cryptographically secure modification detection or integrity checks, like PGP or GPG. When using an external program, be certain to turn off options like persistent undo ([help 'undofile']), backup files ([ help 'backup']), swap files ([ help 'swapfile']), and saving certain information like register contents to the .viminfo file ([ help 'viminfo']), to prevent that the entire file or parts of the file are available on your disk unencrypted. When using Vim's built-in encryption, Vim will encrypt supporting files as discussed above. Using external methods, Vim will not know to encrypt these files. Some older Vim versions (older than 7.1, at least) ask only once for the password -- if you happen to mistype it, then you might write a file which you cannot decrypt. Recent versions of Vim prompt twice for the password on encryption. However, if you use the wrong password on decryption, and then SAVE the gibberish file which results, Vim will still write the file, corrupting your data; so be careful!

The way encryption codes were created differ; some codes were easy to break or to circumvent and other codes were difficult or even impossible to break. The Qomar, a Delta Quadrant species, thought at first that Earth music was a form of encryption. (VOY: "Virtuoso") Encryption was not only used to protect data, such as personal files, but also for communication protocols. The ops protocol on Deep Space 9 was protected by an encryption system. (DS9: "Battle Lines") In Earth's 20th century, some databases were also protected by encryption codes. A 24th century Starfleet tricorder had no problem with breaking such a code. (VOY: "Future's End") As encryption codes differ in complexity – a fractal-based encryption code could lock out the main computer of a Sovereign-class starship in such a way that even the Borg had trouble bypassing it – encrypting or decrypting such codes might take some time. (Star Trek: First Contact) In the 24th century, encryption programs were used to bypass access protocols. (DS9: "The Quickening") Although an encryption sequence could be broken by a computer a person could also connect themselves directly to a terminal by means of a dataport and so try to break the encryption. (DS9: "A Simple Investigation") Hoshi Sato remarked that breaking a Vulcan encryption code would be easier than finding out what Malcolm Reed's favorite food was. (ENT: "Silent Enemy")
