The RSA algorithmFor performing RSA encryption with Java, you luckily don't need to know all the gory details of how RSA works. But it's worth having an overview, at least so that you can understand the terminology. (Note that outside of Java, you do need to know some of these ...

RSA is a short form for Rivest, Shamir, and Adleman, are the people who first publicly described it in 1977. It is an algorithm for asymmetric cryptography which involves the use of two keys. A public key, which can be known to anybody and can be used to encrypt messages, and verify ...
误区三:对Security.Cryptography命名空间不熟悉。“数字签名”一般的做法是:A先计算出文件M的HASH码,再对HASH码进行加密(这个步骤就是签名),再把M(文件M不要加密,第三方可以查阅)和加密后的HASH码传送给B,B再用A的公钥来解密刚才得到的加密HASH码,如果能解密,那就说明这个文件是A发的,具有法律效应。再计算出得...
DES3,通常指的是三重数据加密算法(Triple Data Encryption Algorithm,3DES)或称为Triple DES,是一种对称加密算法。它是基于原有的DES(Data Encryption Standard)算法扩展而来,通过三次DES加密来增强安全性。 BUG弄潮儿 2024/05/11 4840 从小白变RSA大神,附常用工具使用方法及CTF中RSA典型例题 数据加密服务编程算法 ...
From here, signing and verifying work as described in the JCE documentation; the only other thing you need to know is that you can use the "SHA1withRSA" algorithm when you get yourjava.security.Signatureinstance for signing/verifying, and that you want the "RSA" algorithm when you get you...

DSA(Digital Signature Algorithm):DSA是一种数字签名算法,专门用于生成和验证数字签名,常用于身份认证、数据完整性验证等场景。DSA算法基于离散对数的数学难题,相对于RSA算法,它的加密和解密速度更快。 ECC(Elliptic Curve Cryptography):ECC是一种基于椭圆曲线的非对称加密算法,具有与RSA相当的安全性,但在密钥长度较短...
