SQLCipher Multiplatform is a Kotlin Multiplatform library that brings encrypted SQLite support to KMP projects. It unifies database access across Android and JVM, using SQLCipher under the hood, and ships with a JNI-backed JDBC driver for desktop and backend JVM environments

• Unified Kotlin Multiplatform API for encrypted SQLite operations
• JVM support via custom SQLCipher JDBC driver (jdbc:sqlcipher:)
• Android support via SQLCipher for Android integration
• Native payload packaging for major desktop/server JVM platforms
• CI-friendly sample verification flows (CRUD, encrypted-at-rest checks, wrong-key rejection)

platform is combination of platform name + architecture: (linux|macos|windows)-(x64|arm64)

• KMP API targets: JVM, Android
• iOS: not implemented yet
• JVM native payloads: windows-x64, linux-x64, linux-arm64, macos-x64, macos-arm64
• Toolchain baseline: Java 17, Kotlin 2.3.x
• Android baseline: minSdk 24

import io.github.s0d3s.sqlcipher.multiplatform.api.SqlCipherDatabaseFactory

SqlCipherDatabaseFactory.initialize() // JVM no-op; on Android pass applicationContext

val db = SqlCipherDatabaseFactory.open("app.db", "my-secret-key")
db.execute("CREATE TABLE IF NOT EXISTS notes(id INTEGER PRIMARY KEY, text TEXT NOT NULL)")
db.execute("INSERT INTO notes(text) VALUES ('hello')")

val rows = db.querySingleColumn("SELECT text FROM notes ORDER BY id")
println(rows) // [hello]

db.close()

Executable examples live in:

• samples/kmp-basic-app — direct KMP API usage (SqlCipherDatabaseFactory)
• samples/kmp-sqldelight-app — SQLDelight on top of SQLCipher JDBC

Run sample checks:

./gradlew :samples:kmp-basic-app:verifySample
./gradlew :samples:kmp-sqldelight-app:verifySample
./gradlew verifySamples

• sqlcipher-multiplatform/ — KMP library API (commonMain, jvmMain, androidMain)
• sqlcipher-multiplatform-jdbc-core/ — custom JDBC driver (jdbc:sqlcipher:)
