在测试中调用spring-security-crypto的Encryptors时发生IllegalArgumentException

我正在尝试为以下代码编写一个JUnit测试用例。我正在使用spring-security-crypto库的Encryptor。当我尝试运行代码时,我能够成功地对字符串进行加密,但是当我运行测试用例时,却出现了错误。

代码

public String standardEncryption(String value) {
        if (!isNullOrEmpty(value)) {
            return Encryptors.text(password, salt).encrypt(value);
        }
        return value;
    }

Junit测试用例

@Test
    public void can_standardEncryption() {
        String value = someNumericString(10);

        String result = encryption.standardEncryption(value);

        assertThat(result).isNotNull();
        assertThat(result.equals(value)).isFalse();
        assertThat(textEncryptor.decrypt(result)).isEqualTo(value);
        assertThat(result.equals(textEncryptor.encrypt(value))).isFalse();
    }

错误

答案 0 :(得分:1)

听起来可能需要启用更大的按键大小。

默认情况下,Spring Security根据您提供的密码创建一个256位AES密钥。但是,Java 8默认情况下不允许这种大小的键。

如果您的Java版本早于Java 8u151 ,则需要download a jar并将其添加到安装中,用下载的内容替换$JAVA_HOME/jre/lib/security中的内容。

如果您使用的是 Java 8u151或更高版本,则默认情况下会附带此策略jar,但需要通过取消注释$JAVA_HOME/jre/lib/security/java.security中的以下行来启用该策略jar:

crypto.policy=unlimited

或者,我相信OpenJDK默认情况下启用了此功能,因此您也可以关闭JVM。
