RSA Algorithm in cryptography is based on the fact that you can find and multiply large numbers easily but finding the factor of their product is difficult. Mathematical research estimates that if the key value is 100 digits, it would take attackers more than 70 years to find its value. The...
CryptoAPI (often abbreviated as "CAPI") is a set of C-based API which applications (under Windows) can use to access cryptographic services. In particular, cryptographic operations which use keys (e.g. RSA encryption) are delegated to pluggable modules called "CSP" (Cryptographic Service Provide...
Cryptography RSA Algorithm - RSA (Rivest-Shamir-Adleman) is a famous encryption scheme that makes use of a combination of public and private keys. This means you have a non-public key and one that can be shared publicly. Each key can be used to encrypt d
(Robinson, 2003, pp.6) RSA has come to play a vital role in electronic communications. Being the first example in history of the public key cryptosystem and, worth nothing, the only type that has withstood more than three decades of attacks, the RSA has become the choice algorithm for ...

I want to encode and do signature for my string using "SHA256withRSA" algorithm. I could able to see lot of sample code in java using "SHA256withRSA" but in C# I could see first we are hashed data using SHA256 then we are sign hash using RSACryptoServiceProvider. My questions are...
MD5的全称是message-digest algorithm 5(信息-摘要算法,在90年代初由mit laboratory for computer science和rsa data security inc的ronald l. rivest开发出来, 经md2、md3和md4发展而来。 MD5具有很好的安全性(因为它具有不可逆的特征,加过密的密文经过解密后和加密前的东东相同的可能性极小) ...
