AES加密简化版本 - AESEncrypt
函数简介
AES加密简化版本,使用默认参数(CBC模式和PKCS7填充,默认IV为0)。
接口名称
AESEncryptDLL调用
c
long AESEncrypt(long instance, string source, string key);参数说明
| 参数名 | 类型 | 说明 |
|---|---|---|
| instance | 长整数型 | OLAPlug对象的指针,由 CreateCOLAPlugInterFace 接口生成。 |
| source | 字符串 | 源数据。 |
| key | 字符串 | 密钥,字符串长度应为16/24/32个字符,对应AES-128/192/256。 |
