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
