# `bundled-sqlcipher-vendored-openssl` compiles the SQLCipher amalgamation
# (a superset of the stock SQLite `bundled` build — FTS5 etc. included) and
# statically links a vendored OpenSSL libcrypto, so encryption support adds
# no runtime library dependencies. With no `PRAGMA key` applied, SQLCipher
# behaves identically to stock SQLite, so unencrypted indexes are unaffected.

# OLE2 but `cfb`, the reader. See `tests/fixtures/legacy/`.
