DynamicCipher

Types

Creates and configures instances of Cipher on demand.

Whether this cipher is in legacy mode.

abstract val pageSize: Int

Actual size of a database page in legacy mode. Returning 0 is enough outside of legacy mode, the page size is then determined automatically.

abstract val reserved: Int

Number of reserved bytes per database page, used to store a HMAC or other data this cipher scheme needs to verify page consistency.

abstract val salt: Buffer?

Salt for this cipher scheme, or null if Factory.saltSize is 0.

abstract override fun close()

Releases the resources this cipher holds.

abstract fun decryptPage(page: Int, data: Buffer, reserved: Int, hmacCheck: Boolean)

Decrypts a single database page.

abstract fun encryptPage(page: Int, data: Buffer, reserved: Int)

Encrypts a single database page.

abstract fun generateKey(userPassword: ByteArray, rekey: Int, cipherSalt: Buffer?)

Derives an encryption key from userPassword.
