public AESKeyGenerator()

Default constructor that uses system UTC clock and UUID entropy for filename

AESKeyGenerator

public AESKeyGenerator(Clock clock,
 Supplier<String> filenameEntropySupplier)

Constructor for testing purposes.

Parameters:

clock - Clock instance to use.

filenameEntropySupplier - Supplier for entropy.

Method Details

generateDefaultKey

public Path generateDefaultKey(Path secretKeyDirectory)

Generates a default key and writes it to the specified directory. The key filename will be in the format: AES256_YYYY-MM-DD-HHmmss_UUID For example: AES256_2024-03-19-213347_afa7684f-ac0a-4873-b216-d1527841ca72

Parameters:

secretKeyDirectory - Directory to write the key to.

Returns:

Path to the generated key.

getUUIDFilenameEntropy

public static String getUUIDFilenameEntropy()

Generates a random UUID string for entropy.

Returns:

The generated UUID string.
