sqlite数据库的加密与解密

单词创建的数据库：WH_Lexicon.db
利用sqlcipher对数据库进行加密；sqlcipher工具地址
下载之后，编译

$ ./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto -L/usr/local/opt/openssl/lib" CPPFLAGS="-I/usr/local/opt/openssl/include"
$ make

利用sqlcipher加密 WH_Lexicon.db，秘钥：wanhe

$ sqlcipher WubiWords.db
sqlite> ATTACH DATABASE 'encrypted_WH_Lexicon.db' AS WH_Lexicon KEY 'wanhe';
sqlite> SELECT sqlcipher_export('WH_Lexicon');
sqlite> DETACH DATABASE WH_Lexicon;
sqlite> .exit

利用sqlcipher解密 encrypted_WH_Lexicon.db,秘钥：wanhe

$ ./sqlcipher encrypted_WH_Lexicon.db
sqlite> PRAGMA key = 'wanhe';
sqlite> ATTACH DATABASE 'encrypted_WH_Lexicon.db' AS WH_Lexicon KEY ''; 
sqlite> SELECT sqlcipher_export('WH_Lexicon');
sqlite> DETACH DATABASE WH_Lexicon;
sqlite> .exit
