SQLCipher

SQLCipher uses:

SQLCipher is a completely open source software, providing 256 bits.

AES encryption

Source code compilation:

1.

OpenSSL compilation

The compilation of SQLCipher source code needs to rely on libcrypto provided by OpenSSL.

Download the OpenSSL source code, and select the stable version 1.0. 1h here.
