From 6e7971553e021a7fe72987490439bf9a5475fb44 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Sat, 8 Sep 2007 23:27:49 +0000 Subject: Add functions to read and write the AUPD (flash update) image. "--read-aupd aupd.bin" will read (and decrypt) the AUPD image, and "--write-aupd aupd.bin" will write (and encrypt) an image. Also fix a bug in the "diskmove" function which corrupted the AUPD image when a bootloader was installed. So in order to manipulate the aupd image, you need to restore a clean firmware partition, and install the bootloader with this version of ipodpatcher. Decryption functions based on the description and sample code at http://ipodlinux.org/Flash_Decryption git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14644 a1c6a512-1295-4272-9138-f99709370657 --- rbutil/ipodpatcher/arc4.h | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 rbutil/ipodpatcher/arc4.h (limited to 'rbutil/ipodpatcher/arc4.h') diff --git a/rbutil/ipodpatcher/arc4.h b/rbutil/ipodpatcher/arc4.h new file mode 100644 index 0000000000..8bff0e2dc1 --- /dev/null +++ b/rbutil/ipodpatcher/arc4.h @@ -0,0 +1,47 @@ +/* + arc4.h - based on matrixssl-1-8-3-open + +*/ + +/* + * Copyright (c) PeerSec Networks, 2002-2007.
