1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and

Android Development, will inevitably encounter the need to decrypt some of the data content to the local file, or transmission over the network to other servers and devices, but not the use of encryption is absolutely safe, if the encryption

It is important to understand the following for encryption and decryption:The two sides want to communicate, the middle connection may be bugged or even tampered with. The solution is to encrypt the contents of the transmission, using ciphertext to

question: How do I eliminate duplicate values while preserving the order of elements on a sequence?Answer: If the values on the sequence are all hashable types, it is easy to use the collection or generator to solve the problem.　　EG1:　　def dedupe
