微信数据库便是使用这种加密方式，因此可以用来解密微信数据库
安装sqlicipher
直接安装
apt-get install sqlcipher使用源码编译
下载源代码
git clone https://github.com/sqlcipher/sqlcipher.git定义 SQLITE_HAS_CODEC和SQLITE_TEMP_STORE=2
export SQLITE_HAS_CODEC
export SQLITE_TEMP_STORE=2安装openssl和tcl
sudo yum install openssl
sudo yum install tcl进入sqlcipher源码目录进行编译
./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
make
make install编译成功
[root@localhost sqlcipher]# sqlcipher --version

sqlcipher EnMicroMsg.db 'PRAGMA key = "key"; PRAGMA cipher_use_hmac = off; PRAGMA kdf_iter = 4000; ATTACH DATABASE "decrypted_database.db" AS decrypted_database KEY "";SELECT sqlcipher_export("decrypted_database");DETACH DATABASE decrypted_database;'或者
sqlcipher EnMicroMsg.db 'PRAGMA key = "key"; PRAGMA cipher_migrate; ATTACH DATABASE "decrypted_database.db" AS decrypted_database KEY "";SELECT sqlcipher_export("decrypted_database");DETACH DATABASE decrypted_database;'解密得到可用sqlite3打开的decrypted_database.db。
