public key cryptography / 公开密钥加密算法

公钥加密系统使用成对的数学密钥。 The public key can be disseminated widely while its corresponding private key is known only by the owner of the key pair. 任何人都可以使用接收者的公钥加密信息,但只有拥有私钥的接收者才能解密信息。 Additionally, the private key can be used to create a signature to prove the identity of the creator of a message or other files. 可以通过公钥验证此签名。
