Delphi through the secret key of MD5 encryption, nasty! ! ! Online waiting for

CodePudding user response:

What do you mean?
MD5 no keys that
The MD5 encryption is what mean?

CodePudding user response:

MD5 that to key, DES encryption is key, this is two kinds of encryption methods, MD5 is irreversible encryption, DES is reversible encryption algorithm. You are to make it?

CodePudding user response:

Md5 key? Md5 only salt [],,,,

CodePudding user response:

Do you know the Delphi told me, with what method can encrypt decrypt? If there is no secret key can use don't MD5 encryption, for example in detail, the younger brother to learn Delphi soon

CodePudding user response:

Is what I want for a login account and password is encrypted, then only themselves to know, by using the method of decryption hope higher reliability, for example in detail, thanks a lot! Hurry!

That should be searched des encryption algorithms such as the ace of the code

CodePudding user response:

With DSE arithmetic is OK, have a key, to encrypt, decrypt, search for DES PAS files from the Internet, directly introducing projects, and then call the function can, remember to change the key with respect to OK!

Explain that md5 don't need a key, md5 itself is the encryption algorithm, you can use md5 implementation requirements completely,
The md5 algorithm to encrypt only, not decrypt, therefore
First of all, when user registration, user login name and password are using md5 encrypted database,
Then when logging in, the user input user name and password are md5 encryption, and then comparing md5 cryptograph database when registering, if
Agree, is allowed to login, otherwise not allowed to login,

CodePudding user response:

Not specific, the great god still want example

CodePudding user response:

MD5 is based algorithm, itself does not need to key, used for general use HMAC - MD5 authentication, the key is to add salt
