Source files of the wxSQLite3 encryption extension

The following document gives a short overview of all source files of which the SQLite3 Multiple Ciphers encryption extension consists.

Kernel of the wxSQLite3 encryption extension

The following files constitute the kernel of the SQLite3 Multiple Ciphers encryption extension:

Filename	Description
cipher_common.c	Implementation of the common cipher functions
cipher_common.h	Header for the common cipher functions
cipher_config.c	Common cipher configuration functions
cipher_wxaes128.c	Implementation of the wxSQLite3 AES 128-bit encryption extension
cipher_wxaes256.c	Implementation of the wxSQLite3 AES 256-bit encryption extension
cipher_chacha20.c	Implementation of the ChaCha20-Poly1305 encryption extension
cipher_sqlcipher.c	Implementation of the SQLCipher encryption extension
cipher_sds_rc4.c	Implementation of the System.Data.SQLite RC4 encryption extension
codec_algos.c	Implementation of the encryption algorithms
codecext.c	Implementation of the SQLite3 codec API
rekeyvacuum.c	Adjusted VACUUM function for use on rekeying a database file
sqlite3mc.c	Amalgamation of the complete SQLite3 Multiple Ciphers encryption extension
sqlite3mc.h	Header for the additional API functions of the SQLite3 Multiple Ciphers encryption extension
sqlite3mc_vfs.c	Implementation of the Multiple Ciphers VFS
sqlite3mc_vfs.h	Header for the additional API functions of the Multiple Ciphers VFS

All files, except rekeyvacuum.c, are licensed under the MIT license.

rekeyvacuum.c contains a slightly modified implementation of the function sqlite3RunVacuum from the SQLite3 and stays in the public domain.

Cryptograhic algorithms

The following files contain the implementations of cryptographic algorithms used by the wxSQLite3 encryption extension:

Filename	Description
chacha20poly1305.c	Implementation of ChaCha20 cipher and Poly1305 message authentication
fastpbkdf2.c	Implementation of PBKDF2 functions
fastpbkdf2.h	Header for PBKDF2 functions
md5.c	Implementation of MD5 hash functions
rijndael.c	Implementation of AES block cipher
rijndael.h	Header for AES block cipher
sha1.c	Implementation of SHA1 hash functions
sha1.h	Header for SHA1 hash functions
sha2.c	Implementation of SHA2 hash functions
sha2.h	Header for SHA2 hash functions

The files chacha20poly1305.c, fastpbkdf2.*, md5.c, and sha1.* are in the public domain.

The files rijndael.*, are licensed under LGPL-3.0+ WITH WxWindows-exception-3.1.

The files sha2.* are licensed under BSD-3-Clause.

Windows-specific files

The following files are only used under Windows platforms for creating binaries:

Filename	Description
sqlite3mc.def	Module definition specifying exported functions
sqlite3mc.rc	Resource file specifying version information for the SQLite3MultipleCiphers library
sqlite3mc_shell.rc	Resource file specifying version information for the SQLite3MultipleCiphers shell

All files are licensed under the MIT license.

SQLite3 core

The following files belong to the SQLite3 core:

Filename	Description
shell.c	SQLite3 shell application
sqlite3.c	SQLite3 source amalgamation
sqlite3.h	SQLite3 header
sqlite3ext.h	SQLite3 header for extensions
test_windirent.c	Source for directory access under Windows used by fileio extension
test_windirent.h	Header for directory access under Windows used by fileio extension

All files are in the public domain.

SQLite3 extensions

The following files belong to SQLite3 extensions contained in the official SQLite3 distribution:

Filename	Description
carray.c	Table-valued function that returns the values in a C-language array
csv.c	Virtual table for reading CSV files
fileio.c	Functions readfile and writefile, and eponymous virtual table fsdir

shathree.c	Functions computing SHA3 hashes
sqlite3userauth.h	Header for user-authentication extension feature
userauth.c	User-authentication extension feature (modified password hash function)
uuid.c	Functions handling RFC-4122 UUIDs

All files are in the public domain.

External SQLite3 extensions

The following file was posted to the SQLite mailing list:

Filename	Description
extensionfunctions.c	The extension provides common mathematical and string functions

The file extensionfunctions.c does not contain any specific license information. Since it was posted to the SQLite mailing list, it is assumed that the file is in the public domain like SQLite3 itself.
