Bonjour,

je suis à la fin d'un cours sur la cryptographie - Sécurisez vos données avec la cryptographie, aussi j'essaie de mettre tout cela en pratique…

Il s'agit du hachage des mots de passe à l'aide php et sodium.

Ce que j'ai fait:

Code :

sudo apt-get install php

Ce qui n'est pas passé:

Code :

thierry@thierry-VirtualBox:~/Dokumente/php$ sudo pecl install -f libsodium
[sudo] Mot de passe de thierry :
sudo: pecl : commande introuvable

De plus j'ai décommenté extension=sodium:

Code :

thierry@thierry-VirtualBox:~/Dokumente/php$ cat /etc/php/7.4/cli/php.ini | grep sodium
extension=sodium

Ensuite j'ai copié le code proposé dans le cours ici ,et j'ai essayé de le lancer:

Code :

thierry@thierry-VirtualBox:~/Dokumente/php$ sudo php -f /home/thierry/Dokumente/php/prog1.php
PHP Warning: PHP Startup: Unable to load dynamic library 'sodium' (tried: /usr/lib/php/20190902/sodium (/usr/lib/php/20190902/sodium: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/sodium.so (/usr/lib/php/20190902/sodium.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Hello World

Je ne connais pas bien php, mais je ne suis pas une quiche. Sans en avoir jamais fait j'arrive à peu près à lire le petit programme.
echo (comme en bash…)
. (pour appliquer echo deux fois de suite)
PHP_EOL (end of line…)
D'où les trois lignes qui s'affichent en dessous, ok.

Apparemment la librairie sodium ne se charge pas dynamiquement, c'est grave ?

J'aimerais bien réaliser ces TP et que ça se passe bien.
Merci pour votre aide.

Hello,

La commande pecl ne semble pas dispo sur ta machine,

fais un

Code :

sudo apt install php-pear

avant de lancer l'install de la lib

There's more to life than the boy in that mirror.

mozaia

exacte, php-pear n'était pas installé, c'est maintenant installé.

voilà le résultat:

J'ai du nouveau, il faut installer php-dev pour avoir phpize:

Code :

sudo apt install php-dev

Et maintenant (voir lignes 140, 141):

Code :

thierry@thierry-VirtualBox:~$ sudo pecl install -f libsodium

Libraries have been installed in:
/tmp/pear/temp/pear-build-rooty6wLIe/libsodium-2.0.23/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Ça fonctionne

En fait il n'est pas nécessaire (voir déconseillé) de décommenter extension=sodium dans /etc/php/7.4/cli/php.ini, sinon on obtient un Warning comme quoi le module est déjà chargé:

Code :

thierry@thierry-VirtualBox:~$ php -f /home/thierry/Dokumente/php/prog1.php

Oui donc en fait, ta question n'avait rien à voir avec sodium, mais comment installer et compiler une extension PHP.
