Verify package

How to verify the downloaded package?

Follow the steps:

1. Download SHA256SUM and SHA256SUM.asc

2. Get the key used for the signature
   apply for 1.6.1 and new versions
   The key ID is: 8C0C55F7DEC8FC52 (generated in 2021, current)
   The public key is: E4F02524471B195CCEFBD7158C0C55F7DEC8FC52
   

   apply for old versions before 1.6.1
   The key ID is: 702F717E0A17659D (generated in 2020, archived)
   The public key is: 33E5119C5781C1B37E56E580702F717E0A17659D
   gpg --keyserver hkp://hkps.pool.sks-keyservers.net --receive-keys 8C0C55F7DEC8FC52

3. Verify the signature
   gpg --verify kangaroo-1.6.1.210131.sha256sum.asc

4. Check the package with sha256sum
   run the following command from within the download directory to get SHA256 hash:
   sha256sum kangaroo-1.6.1.<else>
   then search the hash in the SHA256SUM file:
   grep <sha256sum output> kangaroo-1.6.1.sha256sum

SQLite

Does Kangaroo compatible with other cipher algorithms? Yes, Kangaroo's default cipher algorithm is ChaCha20, it could compatible with database encrypted with other cipher algorithms like AES128/AES256/ChaCha20/RC4/Ascon-128, and SQLite legacy cipher modes, you could try it with SQLite URI parameters:

// Load database with the legacy SQLCipher Version 2 encryption scheme
file:databasefile?cipher=sqlcipher&legacy=1&kdf_iter=4000
// Attached database with same cipher with main database
// Database file directly
// Attached database with different cipher with main database
// Database file must be URI scheme
file:databasefile?cipher=chacha20

The following table lists the builtin cipher schemes:

Cipher Name	Cipher ID	Preprocessor Symbol	Cipher
