RSA is an algorithm used for Cryptography. It was patented until 2000 in the USA (not the whole world) where now it can be used freely. RSA has a lot of usage examples but it is mainly used for encryption of small pieces of data like key and Digital signatures. RSA is based integer ...

公钥加密标准(Public Key Cryptography Standards, PKCS),此系列标准的设计与发布皆由RSA信息安全公司所制定。包括证书申请、证书更新、证书作废表发布、扩展证书内容以及数字签名、数字信封的格式等方面的一系列相关协议。 目前在使用的最高版本为 PKCS#12,这版本也是我工作中使用最多的版本,此外我还接触过 PKCS#7 版...

The RSA algorithm (Rivest-Shamir-Adleman) is a public key cryptosystem that uses a pair of keys to secure digital communication and transactions over insecure networks, such as the internet. Public key cryptography, also known asasymmetric cryptography, uses two different but mathematically linked key...
提到RSA,我们自然而然的会想到"非对称加密算法",相比于对称加密算法(Symmetric-key algorithm),非对称加密算法不必担心公钥传输被截获的问题。对称加密算法使用相同密钥进行加密、解密操作,如果密钥被截获,第三方就可以随意伪造信息。而对于非对称加密算法,密钥成对出现,即:公钥、私钥唯一配对,私钥由信任中心或者密钥对生...
