cloud.opencode.base.crypto.symmetric.Padding
All Implemented Interfaces:
Serializable, Comparable<Padding>, Constable
public enum Padding extends Enum<Padding>
Padding scheme enumeration for block cipher algorithms. 分组密码算法的填充方案枚举。

Features | 主要功能:

  • PKCS5, PKCS7, NoPadding definitions - PKCS5、PKCS7、NoPadding 定义

Usage Examples | 使用示例:

Padding padding = Padding.PKCS5;
String name = padding.paddingName();

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
  • Null-safe: Partial - 空值安全: 部分

      public static final Padding NO_PADDING
      No padding - Plaintext must be multiple of block size. 无填充 - 明文必须是块大小的倍数。

    • PKCS5

      public static final Padding PKCS5

    • PKCS7

      public static final Padding PKCS7
