I’m trusting experts for that opinion). AES supports three different key sizes, 128, 192, and 256 (the larger the key, the more secure the encryption and the more processing power it takes toencryptor decrypt). Apple uses AES-128 and AES-256 in several places in Mac OS X, including ...
SQLiteCrypt is really fast. Performance is not just an afterthought, we baked it in from the start! Easy to use Same API as original SQLite means you just need to replace SQLite runtime It's safe AES-256 is reliable. Beside that SQLiteCrypt only decrypts one block (page) at time, so...
On-the-fly – SQLCipher encrypts and decrypts in chunks called pages, as needed, so it doesn’t operate on the database all at one time. This means SQLCipher starts up and closes down quickly performs very well even with very large databases ...

EncryptByPassphrase() and DecryptByPassphrase()—利用密码字段产生对称密钥对数据进行加密和解密 因此,加密数据列使用起来相对比较繁琐,需要程序在代码中显式的调用SQL Server内置的加密和解密函数,这需要额外的工作量,并且,加密或解密的列首先需要转换成Varbinary类型。
