i want a simple software to encrypt my data( all kind of files) and lock my computer.
this software must have a simple interface asking for the password or decryption key and prevent them from close this interface by any kind of options like (task manager, restart computer, etc) if closed this will not affect the encrypted data, i mean it must remain encrypted and the only way to decrypt this data is via password or decryption key that will be only with me.
More features :
-Once i open this software, it will start to run background and silent until it encrypt all the data, then it will show the interface and lock the computer (lock here doesn't mean log off no :D, but i mean prevent anyone from using or installing any programs or adding new files i mean completely make the PC useless).
-If someone close the PC and remove the hard and add it to another PC to copy the data this data must remain encrypted and not the only way to encrypt it is to use the decrypt key.
-if possible i want nothing work on this PC expect browsing internet, just browsing, if not possible then no problem i want 100% encrypt and lock.
-in case the interface closed by anyway and i don't want this to happen, i want it to auto run again, the same if computer restart.
Note: once the software opened and the data encrypted, then there is no possible way to decrypt it without the key or password. ( i mean there is no way back)
