Class RawCipherSupport

java.lang.Object

dev.frostlake.functions.scalar.crypto.RawCipherSupport

public final class RawCipherSupport
extends Object

Shared helpers for the raw-key EncryptRaw / DecryptRaw AES-GCM functions: hex BINARY conversion (the engine represents BINARY as an uppercase hex string) and the encryption-method guard.

Field Summary

Fields

Modifier and Type	Field	Description
static final int	GCM_TAG_BITS	GCM authentication-tag length used by ENCRYPT_RAW / DECRYPT_RAW, in bits and bytes.
static final int	GCM_TAG_BYTES

Method Summary

Modifier and Type	Method	Description
static byte[]	binaryBytes(String function, Object arg)	Read a BINARY argument's bytes.
static String	bytesToHex(byte[] bytes)	Encode bytes as an uppercase hex BINARY string, matching the engine's BINARY rendering.
static byte[]	hexToBytes(String function, String hex)	Decode an uppercase-or-lowercase hex BINARY string to bytes.
static void	requireGcm(String function, Object method)	Reject anything but AES-GCM.

Field Details

GCM_TAG_BITS

public static final int GCM_TAG_BITS

Method Details

requireGcm

public static void requireGcm(String function,
 Object method)

Reject anything but AES-GCM. A null method is the Snowflake default (AES-GCM); any explicit method that does not name the GCM mode is refused so that an unsupported mode fails loudly rather than being silently mis-encrypted.

binaryBytes

public static byte[] binaryBytes(String function,
 Object arg)

Read a BINARY argument's bytes. Snowflake types the crypto arguments (plaintext/ciphertext, key, IV, AAD, tag) as BINARY and rejects a VARCHAR with "Invalid argument types" — a hex string is NOT silently accepted. A byte[] is tolerated (an already-unwrapped BINARY).

hexToBytes

public static byte[] hexToBytes(String function,
 String hex)

Decode an uppercase-or-lowercase hex BINARY string to bytes.

bytesToHex

public static String bytesToHex(byte[] bytes)

Encode bytes as an uppercase hex BINARY string, matching the engine's BINARY rendering.
