This tutorial is encrypting hard drives using Kryptos and using the Ice filesystem.

More videos on the way.

Your tutorial has one serious flaw. When you select type of format for encrypted partition, you recommend to never use "Normal", but go for "Quick". This is wrong!. Performing normal, full format of Kryptos partition is critical for keeping your data secret. Sure, it takes several hours, especially for 600 GB partition, but this step is essential. In the process of full formating, the whole partition is filled with random data. Then potential attacker is unable to say how much data is stored, and what is the layout. If you resort to quick format, your privacy is illusion. Attack on such badly prepared volume is much, much easier.

Quickformatting a Kryptos volume is only safe if it has been full-formatted with Kryptos before and is just being reformatted.

On the other hand, I guess it will be safe, as long as you are going to fill the partition "almost fully"? Of course it's still the best to format it fully "just in case".

One thing I have been wondering is interoperability with other operating systems (mainly linux), thought of setting up an encrypted drive for use with multiple operating systems.

Also, has anyone done any benchmarks? Mainly wondering how much it would affect f.ex. video playback (as it needs to use some CPU for decryption)

No. Any unused space is a clue for attacker. If I feel that some of my data need Kryptos, I reject any compromises.

In case of real partitions it may be difficult, but you can also have "hardfiles". I've tested with success interoperability between Kryptos and TrueCrypt on Windows. It works. Because I've stored my hardfile on FAT-32 formatted pendrive, I was limited to 2 GB, but it was enoug for me. I guess you can also exchange real partitions on portable devices if you put MBR on them (who knows, Linux may also handle RDB), but have not tested it.

Also, has anyone done any benchmarks?

I've done some in an article written for Polskie Pismo Amigowe. Original article is in Polish, so here is a short summary:

Efika: disk raw read: 5.2 MB/s, copy unencrypted to unencrypted: 2.6 MB/s, copy unencrypted to encrypted: 1.3 MB/s, copy encrypted to unencrypted: 1.3 MB/s, copy encrypted to encrypted: 1.0 MB/s.

Pegasos II: disk raw read: 40.0 MB/s, copy unencrypted to unencrypted: 16.2 MB/s, copy unencrypted to encrypted: 7.5 MB/s, copy encrypted to unencrypted: 6.8 MB/s, copy encrypted to encrypted 4.8 MB/s.

In both cases single AES cipher and SHA-512 hash were used.

It doesn't say "MAC" in the requester because "the boot partition on MorphOS is a MAC boot partition" but because the selected HDD has a MAC partition scheme (vs. MBR or RDB, which you mention subsequently), outside MorphOS called APM as in Apple Partition Map. It's entirely possible to have a MAC-partioned (or APM-partitioned, as most non-MorphOS users would probably say) HDD without any HFS(+) partition on it so that the Mac OpenFirmware wouldn't even be able to boot from it.
And the file size limit with SFS is rather 2 GiB than 8 GiB.

@bash64,

I hope you will continue doing more tutorial videos, as they can be very useful for new users, BUT I hope you will be better prepared for future videos, so that you do not have so many long pauses and/or you will edit out the parts of the video where you encounter problems you did not expect.

This will make your tutorial videos look more professional and reflect better on MorphOS3.x in general. I hope you don't take this constructive criticism personally, just some friendly advice. I give you all the credit for taking the time to create any tutorial videos, as we continue to gain more new MorphOS3.x users, these videos will become more valuable.

I did not know that 1TB PATA drives were available? When I purchased a replacement PATA drive for my G4 PowerBook about 18 months ago, the largest size available was only 320gb, which I have in my 15" 1.67GHz G4 PowerBook. I think I will get a 1TB drive for my 17" 1.67GHz G4 PowerBook, so I will have more storage room to install a triple booting MorphOS3.x/MacOSX10.5.8/Linux Mint PPC operating systems setup.

1) The 1TB drive in my powerbook is a SATA. See my other video where I convert a powerbook from ide to sata.
2) Yes, everyone, there are mistakes in the video and incorrect information. Being a noob I did my best.
3) Was not aware that wihtout a full format you could be compromised. I figured that filling the drive up would take care of that.
4) Mac paritioning. I maintain my position that I am completely ignorant of any and all MAC partitioing.
5) I can redo the video removing pauses and hesitation and reupload.
6) I have fully tested compatibility between Kryptos and Truecrypt with files and partitions. It works flawlessly. In my raidbox I keep a windows MBR drive and an Amiga RDB drive. I can mount the windows drive from either machine. As far as performance...I had to put an SSD in my windows laptop just to get back to normal speed from using truecrypt on the system drive. It does slow things down.
7) SFS file size limit. I have seen different information based on whether it was SFS/0 or SFS/2. If you say its 2GB then ok.

Seriously, don't mind the criticism. I was more concerned that know one would watch at all. The heated criticism was fully expected ahead of time. Saw you coming, I have known this group for too long now to not expect criticism and lots of it.

Next video will be using P2P. The learning curve with ML Donkey is a little steep. The interface is not intuitive in the least bit. It leans more towards driving you mad. I know you will find mistkaes in that video too.
Also, want to do one on using panels. Ambient vs Poly_Net. I pulled hairs out of my head trying to figure out how to add a button to a panel.

I was referring to the MorphOS-native version of SFS that comes with the OS. AFAIK, with that the file size limit is 2 GiB no matter what. Regarding the m68k version in SFS\0 mode, I've read conflicting information (2 GiB vs. 4 GiB). And yes, the SFS\2 mode of the m68k version may allow for more than 4 GiB file size, but it seems we may not be able to properly leverage that feature:

Hmmmmmmmmmmmmmmmm...................

When I try to take a backup to an SFS parition the backup craps out right at 4GB.
Happened just last night.

> want to do one on using panels.

MorphOS 3.2 is supposed to feature an all new panel system anyway :-)

> When I try to take a backup to an SFS parition the backup craps out right at 4GB.

Is that using MorphOS-native SFS or m68k SFS\2?

MorphOS native.

Really? Goody. A 3rd panel system to review.


Please God, let there be a transparency option.
