conn.execute("PRAGMA key=’mypassword’")若忘记设置密钥，后续操作会提示文件非数据库或损坏。给已有数据库加密需要导出数据到新库。先打开普通数据库执行ATTACHDATABASE命令，指定新库路径和加密密码：ATTACH DATABASE ’encrypted.db’ AS encrypted KEY ’secret’;接着执行SELECTsqlcipher_export(’encrypted’);...
输入命令4,SELECT sqlcipher_export(‘plaintext’); 输入命令5,DETACH DATABASE plaintext; 命令解释: 命令1,要操作加密的数据库 命令2,输入加密数据库的密码 命令3,新建了一个数据库plaintext.db, 密码是空【两个单引号中间是空】 命令4,拷贝加密数据库中所有的数据到plaintext.db中 ...

Is the sqlcipher_export function supposed to copy the user_version pragma between plain and encrypted databases? It gets stripped for some reason when I do encryption/decryption.. As far as I remember it was working in the beginning of my tests, that why I am asking what is the expected ...
