SQLite with encryption/password protection

I'm just learning to use SQLite and I was curious if such is possible:

1. Encryption of the database file?

2. Password protect opening of the database?

PS. I know that there is this "SQLite Encryption Extension (SEE).", but according to the documentation, "The SEE is licensed software...." and "The cost of a perpetual source code license for SEE is US $2000."

Here are a few implementations:

• SQLite Encryption Extension (SEE) - The official implementation (commercial)
• SQLite3 Multiple Ciphers - An encryption extension for SQLite with support for multiple ciphers (open source, documentation here)
• SQLCipher - Uses openSSL's libcrypto to implement encryption (commercial, open source version available here)
• SQLiteCrypt - Custom implementation, modified API (commercial)
