密文(cipher text):明文消息经过某种编码后,得到密文消息。 加密(encryption):将明文消息变成密文消息。 解密(decryption):将密文消息变成明文消息。 算法:取一个输入文本,产生一个输出文本。 加密算法:发送方进行加密的算法。 解密算法:接收方进行解密的算法。 密钥(key):只有发送方和接收方理解的消息 对称密钥加密(...
Reducing the SSL encryption and decryption load of the intranet server After restoring HTTPS traffic to HTTP traffic, the device can configure serverload balancing(SLB) on the HTTP traffic to implement refined traffic scheduling and focus on main functions of the traffic. ...
In addition, SSL-encrypted traffic detection requires a large number of encryption and decryption operations. IfSSLdecryption is performed on all SSL traffic, the forwarding performance of the firewall is affected. Therefore, you need to configure an SSL-encrypted traffic detection policy to decrypt ...
vi pt.txt(建立一个文件,名字:pt.txt) 在文件中输入内容:hello,encryption and decryption 然后利用上面的加密指令加密(注意openssl的路径要写对,/opt/openssl/bin/openssl,当然相对路径也ok,这是linux的相关知识),并对加密后的文件命名为:ct.bin(二进制的,名字随便) 然后查看ct.bin 的内容,发现全是乱码(传染...
algorithms are less secure but provide rapid encryption and decryption. The length of the key that is used for encryption affects the level of security; the longer the key, the more secure the data. SSL defines cipher suites to specify cryptographic algorithms that are used during an SSL ...
The SSL protocol is designed to be as efficient as securely possible. However, encryption and decryption are computationally expensive processes from a performance standpoint. It is not strictly necessary to run an entire web application over SSL, and it is customary for a developer to decide which...
SSL:(Secure Socket Layer,安全套接字层),为Netscape所研发,用以保障在Internet上数据传输之安全,利用数据加密(Encryption)技术,可确 保数据在网络上之传输过程中不会被截取。当前版本为3.0。它已被广泛地用于Web浏览器与服务器之间的身份认证和加密数据传输。 SSL协议位于TCP/IP协议与各种应用层协议之间,为数据通讯...
Thus, the user sees the CA certificate configured for the SSL decryption rule instead of the certificate from www.cisco.com. The user must trust the certificate to complete the connection. The FTD device then performs decryption/re-encryption in both directions for traffic between the user and ...
The OFB method creates a synchronous stream cipher. This technique preserves error correction codes. The encryption and decryption processes are exactly the same. Counter Mode (CTR) The CTR method is similar to OFB in that it also creates a synchronous stream cipher. However, it uses a counter...
opensslthe OpenSSL command line tool, a swiss army knife for cryptographic tasks, testing and analyzing. It can be used for creation of key parameters creation of X.509 certificates, CSRs and CRLs calculation of message digests encryption and decryption ...
