This is my demand:
- User content is ultimately stored on the server side, but the preservation of data is encrypted
- Server side, that is, site technical staff, can not have any way to decrypt the contents of the user, as the user’s password as stored on the server side is a long list of md5 encrypted characters.
- For encryption, we can temporarily consider only the text
The same as the password I want to process the data, but these data need to output to the user, so i have to decrypt the data on the client-side ,
what can i do ,
thanks
updated:
if i use javascript obfuscator on my javascript data , How much chance to be cracked by somebody .
Encrypt and decrypt on the client, never store key in the server side.
See jsencryption for an example of client side encryption.
