CryptoVerif Installation

Instructions for installing CryptoVerif.

Installing the binary package (Windows)

On Windows, the recommended way is to use the precompiled binaries here. After accepting the license twice, you will download a file named Uncompress this file in the directory of your choice. This will create a subdirectory named cryptoverif1.19.

Building from Source (Linux, Mac, Windows with Cygwin)

Prerequisite : OCaml version 3.00 or higher. If you don't have OCamnl installed already we recommend installing a "modern" version such as 4.01 or 4.02.

Download CryptoVerif sources:


Uncompress the archive using tar:

 gunzip cryptoverif1.19.tar.gz
 tar -xf cryptoverif1.19.tar

or if you have GNU tar:

 tar -xzf cryptoverif1.19.tar.gz

This will create a directory named cryptoverif1.19 in the current directory. Go into this directory, and build the programs:

 cd cryptoverif1.19


Text editor: Emacs mode for CryptoVerif

You will need a text editor to type examples. Any text editor is ok. If you happen to use emacs, there is an emacs mode for CryptoVerif that will give you syntax coloring. To install it:

  1. Copy the file cryptoverif1.19/emacs/cryptoverif.el of the CryptoVerif distribution to a directory where Emacs will find it (that is, in your emacs load-path)
  2. Add the following lines to your .emacs file:
 (setq auto-mode-alist
       (cons '("\\.cv[l]?$" . cryptoverif-mode) 
       (cons '("\\.ocv[l]?$" . cryptoverifo-mode) auto-mode-alist)))
 (autoload 'cryptoverif-mode "cryptoverif" "Major mode for editing CryptoVerif code." t)
 (autoload 'cryptoverifo-mode "cryptoverif" "Major mode for editing CryptoVerif code." t)


You will need a shell to run CryptoVerif. Under Windows, you may use the Windows command line, although there are better shells, such as the cygwin terminal if you use cygwin. Under Unix, the terminal is fine.


If you want to run protocol implementations generated by CryptoVerif (which will not be required during the school), you need to install the OCaml cryptographic library Cryptokit, version 1.9. This library is available at

For opam users, you can install it just by running "opam install cryptokit". Others should follow the installation instructions provided with the library. Additionally, you need to either

  1. arrange so that the installed cryptokit library is in subdirectory "implementation/cryptokit" of the CryptoVerif distribution (possibly via a symbolic link)
  2. or install the cryptokit library in the "cryptokit" subdirectory of the Caml standard library
  3. or modify the variable CRYPTOKIT in the scripts

so that the cryptokit library is included.
