[other] [symmetric_cipher] AES-XTS 可调窄分组模式加解密(IEEE 1619 / NIST SP 800-38E)。algorithm 可选 AES128XTS(key 32B = 数据密钥 16B + 调组密钥 16B)或 AES256XTS(key 64B = 32B + 32B)。tweak_in_hex 为 16 字节调整值,编码数据单元编号/扇区地址,密文与数据单元位置绑定。process_type 可选 Encrypt / Decrypt(两个变换不同,须显式声明)。输入 16B ~ 16MB,无填充,密文与明文等长;非 16 倍数的尾部自动走密文窃取(ciphertext stealing)。模式特点:各数据单元独立加密,支持并行与随机访问,同一数据单元加解密自同步;同一密钥下 tweak 严禁重复使用(否则两个数据单元明文相同会直接暴露相等关系);XTS 只提供保密性、可塑性攻击下无认证,需要防篡改时在外层叠加 AEAD 或签名。典型使用场景:BitLocker / LUKS2 / FileVault 全盘加密,AMD SEV-SNP 以 AES-256-XTS + VEK 加密 guest 内存(tweak 按物理地址派生,每页唯一),Intel TDX 内存加密同族。返回字段:output_data_in_hex、output_length、output_sha256、algorithm。
