LockBox 3

Wvg8gWlkvHbb8WloO0jmUQ==

这是以16进制输出的字符，不是base64输出的结果。

cipherText:

ECB模式下IV向量忽略不用，用PHP加密结果也是

128/256都是 6a3cbb16daef0ae0

加密后是8个字符， (106, 60, 187, 22, 218, 239, 10, 224)=8个，ascii是j<;'#$16'Zo'#$A'`,base64是ajy7FtrvCuA=

转换成16进制成了16个字符，(54, 65, 51, 67, 66, 66, 49, 54, 68, 65, 69, 70, 48, 65, 69, 48)=16个，

ascii是6a3cbb16daef0ae0，base64：NmEzY2JiMTZkYWVmMGFlMA==
