    签名和验证-Sign

    介绍

    Hutool针对java.security.Signature做了简化包装，包装类为：Sign，用于生成签名和签名验证。

    对于签名算法，Hutool封装了JDK的，具体介绍见：https://docs.oracle.com/javase/7/docs/technotes/guides/security/StandardNames.html#Signature：

    1. // The RSA signature algorithm
    2. NONEwithRSA
    4. // The MD2/MD5 with RSA Encryption signature algorithm
    5. MD2withRSA
    6. MD5withRSA
    8. // The signature algorithm with SHA-* and the RSA
    9. SHA1withRSA
    10. SHA256withRSA
    11. SHA384withRSA
    12. SHA512withRSA
    14. // The Digital Signature Algorithm
    15. NONEwithDSA
    17. // The DSA with SHA-1 signature algorithm
    18. SHA1withDSA
    20. // The ECDSA signature algorithms
    21. NONEwithECDSA
    22. SHA1withECDSA
    23. SHA256withECDSA
    24. SHA384withECDSA
    25. SHA512withECDSA

    使用

    1. byte[] data = "我是一段测试字符串".getBytes();
    2. Sign sign = SecureUtil.sign(SignAlgorithm.MD5withRSA);
    3. //签名
    4. byte[] signed = sign.sign(data);
    5. //验证签名
    6. boolean verify = sign.verify(data, signed);
