From the Home Screen:

[PRGM] [PRGM] [APPS] then you are in the Apps menu

[PRGM] [PRGM] [2ND] [+] then you are in the Memory menu

When saying that you have to reset all memory to use Krolypto again, that is not true. With DoorsCS6 by Kerm Martain, just erase the file called "calcdb2" and Krolypto is avaliable for use again.

Krolypto is a really good way to lock out normal people, but the advanced users can't be tricked. I got some advanced and regular calculator users to try to break through Kroypto with Omnicalc and DoorsCS6:

1 out of 5 advanced users fully trashed Kroylpto's protection with only a RAM reset

2 out of 5 advanced users got past the startup lock by resetting the RAM

0 out of 7 regular users got past any Krolypto security

Usage: 9/10 (Easy, but to protect your keys, you have to archive AppVar krolypto)

Memory: 10/10 (Its an Application)

Compatibility: 2/10 (ruins MirageOS hooks, drops protection with Omnicalc, and DoorsCS6 can override Krolypto)

Encryption: 10/10 (unbeatable)

Quality: 9/10 (scrolling through programs to encrypt/decrypt take a while)

Overall w/Omnicalc and DoorsCS6: 4/10 (You're very vunerable with Omnicalc and DoorsCS6)

The “Krolypto” application is great. It really encodes your programs. And the security it offers is the best around. There is no way around it except for to pull every battery. This application is that secure. So this is a must for programers and people who just don't want other people messing around with their calc.

‘Krolypto v1.3,” now with the added compatibility with “Symbolic” and “MirageOS,” is a nice little Application to protect your 83+. It has all the password protecting that one would need for their calculator, with APPs protection, memory protection and even startup protection. It is very easy to setup but I will warn you: don't forget your password. You will find yourself holding down [Del] and pulling the batteries because it is that secure.
