Objective: Whether the password is stored in the project or whether the file is the same file, will use the MD5 algorithm, today to summarize the MD5 encryption algorithm. What is MD5 encryption? MD5 English full name "Message-digest algorithm 5", translated by "Message digest algorithm 5", from the MD2, MD3, MD4 evolved, is a one-way encryption

When chatting with others yesterday, others put Base64 as encryption. I'm not a word, but as an IT technician I think it's common sense to distinguish between encryption and coding.It ' s unfortunate that the words encryption and encoding tend to get used as synonyms. In cryptography they mean, different things.In short:
