Security | encryption | Algorithm in cryptography, there is an ideal encryption scheme, called a secret garbled this (one-time pad). One-time pad algorithm has the following requirements: 1, the key must be randomly generated 2, the key can not be
Objective:
For the SHA Safe hashing algorithm, before how to use, just stay in the heard of the stage, today in the picture Caching framework Glide source code found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption
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
