WebApr 20, 2024 · RSA 密码算法与签名. RSA是一种公钥密码算法，RSA的密文是对代码明文的数字的 E 次方求mod N 的结果。也就是将明文和自己做E次乘法，然后再将其结果除以 N 求余数，余数就是密文。RSA是一个简洁的加密算法。E 和 N 的组合就是公钥（public key）。 WebRSA is the most widespread and used public key algorithm. Its security is based on the difficulty of factoring large integers. The algorithm has withstood attacks for more than 30 years, and it is therefore considered reasonably secure for new designs. The algorithm can be used for both confidentiality (encryption) and authentication (digital ...
