I am exploring the Universe data encryption features... Its my first try at
this really.
I have decent understanding off ssh and ssl, just not the U2 stuff.
My questions are...
Where is a safe place to store the "key" (as referred to in the docs) that
the function needs to do encrypting and decrypting?
How would I generate this key?
Do I use the same key every time?
Is there a thing to generate a key... like in ssh?
For example, lets say I have a program that encrypts the user's password and
then writes it to the data file like so...
*A test for storing encrypted passwords.
OPEN \BAS.USERS\ TO f_bas_users ELSE
CRT \Cannot open BAS.USERS file.\
STOP
END
*
CRT \Enter your email address: \:
input email_address
CRT \Enter your password: \:
input password
*
key = \thisismykey\
result = \\
encrypt_status = \\
encrypt_status = ENCRYPT(\des3\, 1, password, 1, key, 1, 1, \\, \\,
result, 1)
CRT user_password
*Apparently a status of 0 is a success. Which is just plain weird.
IF encrypt_status = \0\ THEN
WRITEV result ON f_bas_users,email_address,3
END
----------------------
Now lets say I want to check the password to see if it is correct and
decrypt the data to do that...
*A test for reading encrypted passwords.
OPEN \BAS.USERS\ TO f_bas_users ELSE
CRT \Cannot open BAS.USERS file.\
STOP
END
*
CRT \Enter your email address: \:
input email_address
CRT \Enter your password: \:
input password
*
READV stored_password FROM f_bas_users,email_address,3 ELSE
stored_password = \\
END
key = \thisismykey\
result = \\
decrypt_status = \\
decrypt_status = ENCRYPT(\des3\, 3, stored_password, 1, key, 1, 1, \\,
\\, result, 1) ; *This is actually decrypting, the 3 indicates that.
*Apparently a status of 0 is a success. Which is just plain weird.
IF decrypt_status = \0\ THEN
CRT \This is the stored password decrypted from the file.\:result
CRT \This is the password entered by the user.\:password
END
----------------
So... isn't it kind of pointless to store the key in plain text in the
program?
Storing the key in plain text in the file also seems pointless?
Thoughts?
