[Résolu] php sodium chiffrement

php sodium chiffrement [Résolu] - PHP - Programmation

Marsh Posté le 28-09-2021 à 11:27:57    

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 :
  1. sudo apt-get install php


Ce qui n'est pas passé:

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


De plus j'ai décommenté extension=sodium:

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


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

Code :
  1. thierry@thierry-VirtualBox:~/Dokumente/php$ sudo php -f /home/thierry/Dokumente/php/prog1.php
  2. 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
  3. 55eed5b8a36a8e39c77a6b80bc6515582dd7e01a94f7f83b42242614ad7e5d55
  4. e55cad32fe8af7734495934dd141e1ad5c7d79545f4c22d6b46e79
  5. Hello World
  7. thierry@thierry-VirtualBox:~/Dokumente/php$ php -f /home/thierry/Dokumente/php/prog1.php
  8. 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

  10. becbf38c259633d9cfc6b49495122eee916786a91497709bd06b8c
  11. 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,

  120.    - have your system administrator add LIBDIR to `/etc/ld.so.conf'

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 :
  1. thierry@thierry-VirtualBox:~$ php -f /home/thierry/Dokumente/php/prog1.php
  2. PHP Warning:  Module 'sodium' already loaded in Unknown on line 0

En commentant extension=sodium, impeccable !

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