org.springframework.vault.security.VaultBytesKeyGenerator

All Implemented Interfaces:

BytesKeyGenerator

public class VaultBytesKeyGenerator
extends Object
implements BytesKeyGenerator

Random byte generator using Vault's transit backend to generate high-quality random bytes of the configured length.

Using Vault ensures to use a high-entropy source preventing to consume entropy of the local machine.
