解决方案

排除

bcprov-jdk14 依赖  可以通过maven插件去查找

        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>

			<exclusions>
				<exclusion>
					<artifactId>bcprov-jdk14</artifactId>
					<groupId>bouncycastle</groupId>
				</exclusion>
				<exclusion>
					<artifactId>bcprov-jdk14</artifactId>
					<groupId>org.bouncycastle</groupId>
				</exclusion>
			</exclusions>
        </dependency>

添加依赖

        <!-- https://mvnrepository.com/artifact/org.bouncycastle/bcprov-jdk18on -->
        <dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcprov-jdk18on</artifactId>
            <version>1.77</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.bouncycastle/bcpkix-jdk18on -->
        <dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcpkix-jdk18on</artifactId>
            <version>1.77</version>
        </dependency>

		<dependency>
