The functionality of Data Encryption, which is realized with the help of the TUniEncryptor component, allows to encrypt individual fields in database tables. In turn, no third-party application will be able to work with encrypted databases, created with the use of UniDAC The difference between Database File Encryption and Data Encryption. When using UniDAC, it is possible to work only with encrypted databases, created with the use of UniDAC. Therefore, implementation of Database File Encryption in UniDAC is incompatible with other implementations. Important note: there are no strict standardized requirements for implementation of database file encryption in SQLite. the AES encryption algorithm with a key size of 256 bits.the AES encryption algorithm with a key size of 192 bits.the AES encryption algorithm with a key size of 128 bits.To encrypt/decrypt the database file, one of the following encryption algorithms can be used: change the encryption key of the encrypted database.connect and work with the encrypted database.UniDAC provides built-in capabilities for Database File Encryption, which becomes available when working in Direct mode.ĭatabase File Encryption, built in UniDAC, allows to:
UniDAC functionality for Database File Encryption Therefore, usually, to work with encrypted databases one has to either use a custom-built client library with encryption support, or create an own library from the source code, available on the SQLite website. This is a low-level encryption "on the fly", it is implemented at the level of the SQLite client library and is completely transparent to the applications working with the database.īut, the fact is that in the client libraries available at the official SQLite website, the algorithms of database file encryption are not implemented. This means that encoding/decoding is applied to a database file, in the moment of execution of the file read/write operations. The SQLite architecture provides the functionality for work with encrypted databases. What constitutes Database File Encryption
