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Signature,具体介绍见:https://docs.oracle.com/javase/7/docs/technotes/guides/security/StandardNames.html#Signature (opens new window):
// The RSA signature algorithm
NONEwithRSA
// The MD2/MD5 with RSA Encryption signature algorithm
MD2withRSA
MD5withRSA
// The signature algorithm with SHA-* and the RSA
SHA1withRSA
SHA256withRSA
SHA384withRSA
SHA512withRSA
// The Digital Signature Algorithm
NONEwithDSA
// The DSA with SHA-1 signature algorithm
SHA1withDSA
// The ECDSA signature algorithms
NONEwithECDSA
SHA1withECDSA
SHA256withECDSA
SHA384withECDSA
SHA512withECDSA
# 使用
byte[] data = "我是一段测试字符串".getBytes();
Sign sign = SecureUtil.sign(SignAlgorithm.MD5withRSA);
//签名
byte[] signed = sign.sign(data);
//验证签名
boolean verify = sign.verify(data, signed);
