很抱歉,根据提供的引用内容,无法回答关于发送邮件和解密时出现的javax.crypto.IllegalBlockSizeException错误的问题。这个错误通常是由于加密或解密时输入的数据长度不是8的倍数所导致的。建议您检查您的代码或输入数据,确保其长度是8的倍数。如果问题仍然存在,您可以尝试查看相关的文档或寻求专业人士的帮助。

javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher
javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher是AES加密解密的报错异常。这个异常的意思是在使用AES解密时,解密的字符串的长度必须是8的倍数。通常,这种异常是由于解密的数据长度不正确导致的。
可能的原因是在解密过程中,传入的密文长度不是8的倍数。解决这个问题的方法是确保在解密之前,对密文进行正确的填充操作,使其长度为8的倍数。常用的填充方式包括PKCS5Padding和PKCS7Padding。
报错javax.crypto.IllegalBlockSizeException: Input length must be multiple of 16 when decrypting with padded cipher 的解决方法
引用中提到,当使用AES解密时,报错javax.crypto.IllegalBlockSizeException: Input length must be multiple of 16 when decrypting with padded cipher的意思是解密字符串的数组长度必须是16的倍数。所以解决这个问题的方法就是确保传入解密方法的字符串长度是16的倍数。你可以在加密之前,将原始字符串进行填充,使其长度符合要求。在解密之前,也需要确保解密字符串的长度是16的倍数。具体的实现方法可以参考代码中的示例中的相关部分。<em>1</em><em>2</em><em>3</em>
