我已经写了一个代码在beanshell加密和解密在Jmeter，但不知何故它不工作。我得到错误：第19行第82列的In file: inline evaluation of: ``import java.security.InvalidAlgorithmParameterException; import java.security.In . . . '' Encountered "}"。我已经在测试计划中添加了加密jar，但问题仍然存在。
附件是代码。
正在工作：
1.我生成一个随机字符串（R1），并使用RSA算法用公钥加密它。
1.使用密钥R1，我需要使用AES算法、CBC模式、PKCS7Padding对请求正文进行加密。
