No robot: encrypt text on web page
The original Norbt (No robot) service has appeared on the Web , which allows anyone who wants to create their own page with encrypted text in a couple of seconds . You can see the contents of the page only by knowing the password.
The creators of the web application claim that strong cryptography is used here, so that even if the server is hacked, the hacker will not be able to decrypt the text. The data on the server is stored in the following form:
Answer: SHA1 (answer + salt1), salt1
Text: AES128 (SHA1 (answer + salt2), IV, Mode.CFB, text), salt2, IV
That is, to decrypt the text, the hacker will have to crack or SHA1 (answer + salt1), or AES128.
Listening to traffic by cracking SSL will also not help the hacker, because all encryption operations are performed in the browser.
