SQLCIPHER PHP 7.4 UBUNTU

 This took me too much time to implement, after two hours of searching, I didnt found and documentation of how to compile sqlcipher support of ext/sqlite3 of php.

I also posted this to a gist in my github: https://gist.github.com/durich/bf15c091c6d59b042caa142950eaf252

 

So I'm posting my recipe to compile sqlcipher support to the ext-sqlite3 of php, any recommendations to refined this process is welcome:

#this is for php  7.4 included in distro, may work in other versions of php 7
#install library
apt-get install php7.4-dev build-essential

#download and compile sqlcipher
cd /usr/local/src/
git clone https://github.com/sqlcipher/sqlcipher

#compile
cd sqlcipher

./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
make

#download php
cd /usr/local/src/
wget https://www.php.net/distributions/php-7.4.9.tar.bz2

#extract files
tar -xvjf php-7.4.9.tar.bz2

#enter directory
cd php-7.4.9/ext/sqlite3

#run phsize
phpize

#copy m4 file
mv config0.m4 config.m4

#run configure
SQLITE_LIBS="/usr/local/src/sqlcipher/.libs/" SQLITE_CFLAGS="-I/usr/local/src/sqlcipher/ -DSQLITE_HAS_CODEC -DSQLITE_TEMP_STORE=2" ./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypt -L/usr/local/src/sqlcipher/.libs/"  --libdir=/usr/local/src/sqlcipher/.libs/sqlite3.o

#run make
make

#check module file sqlite3.so, if less than 110,000 byes, sqlcipher not included
ls -l modules/ -l

#another to check
strings modules/sqlite3.so | grep  sqlcip

#include /usr/local/src/sqlcipher/.libs/sqlite3.o in the linking, this step is extra,  because I'm noob on configure flags and c++ flags, suggestion are welcome
vim sqlite3.lo

#change line
pic_object='.libs/sqlite3.o'

#to
pic_object='.libs/sqlite3.o /usr/local/src/sqlcipher/.libs/sqlite3.o'

#save file

#execute again
make

#check, if greateher thank 110,000 bytes, it linked ok
ls -l modules/ -l

#check strings, should be alot of functions
strings modules/sqlite3.so | grep cip

#copy compiled module tu modules, in php7.4 case the directory is /usr/lib/php/20190902/
cp modules/sqlite3.so /usr/lib/php/20190902/

#crear  ini files to load in fpm, apache or cli, my case is cli and fpm
echo extension=sqlite3.so > /etc/php/7.4/cli/conf.d/20-sqlite3.ini
echo extension=sqlite3.so > /etc/php/7.4/fpm/conf.d/20-sqlite3.ini

#test php should giver versions in $version->fetchArray
query("PRAGMA cipher_version");
if($version){
     var_dump($version->fetchArray());
} else {
    throw new Exception($db->lastErrorMsg());
 }
$db->exec("PRAGMA key = '$password';");
$db->exec("PRAGMA cipher_page_size = 1024;");
$db->exec("PRAGMA kdf_iter = 64000;");
$db->exec("PRAGMA cipher_hmac_algorithm = HMAC_SHA1;");
$db->exec("PRAGMA cipher_kdf_algorithm = PBKDF2_HMAC_SHA1;");
