Issue Date: 20/12/2007
This file contains the compilation options for AES (Rijndael) and code
that is common across encryption, key scheduling and table generation.
OPERATION
These source code files implement the AES algorithm Rijndael designed by
Joan Daemen and Vincent Rijmen. This version is designed for the standard
block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
and 32 bytes).
This version is designed for flexibility and speed using operations on
32-bit words rather than operations on bytes. It can be compiled with
either big or little endian internal byte order but is faster when the
native byte order for the processor is used.
THE CIPHER INTERFACE
The cipher interface is implemented as an array of bytes in which lower
AES bit sequence indexes map to higher numeric significance within bytes.
uint8_t (an unsigned 8-bit type)
uint32_t (an unsigned 32-bit type)
struct aes_encrypt_ctx (structure for the cipher encryption context)
struct aes_decrypt_ctx (structure for the cipher decryption context)
AES_RETURN the function return type
C subroutine calls:
AES_RETURN aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
IMPORTANT NOTE: If you are using this C interface with dynamic tables make sure that
you call aes_init() before AES is used so that the tables are initialised.

/* 1. BYTE ORDER WITHIN 32 BIT WORDS
The fundamental data processing units in Rijndael are 8-bit bytes. The
input, output and key input are all enumerated arrays of bytes in which
bytes are numbered starting at zero and increasing to one less than the
number of bytes in the array in question. This enumeration is only used
for naming bytes and does not imply any adjacency or order relationship
from one byte to another. When these inputs and outputs are considered
as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
In this implementation bits are numbered from 0 to 7 starting at the
numerically least significant end of each byte (bit n represents 2^n).
However, Rijndael can be implemented more efficiently using 32-bit
words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
into word[n]. While in principle these bytes can be assembled into words
in any positions, this implementation only supports the two formats in
which bytes in adjacent positions within words also have adjacent byte
numbers. This order is called big-endian if the lowest numbered bytes
in words have the highest numeric significance and little-endian if the
opposite applies.
This code can work in either order irrespective of the order used by the
machine on which it runs. Normally the internal byte order will be set
to the order of the processor on which the code is to be run but this
define can be used to reverse this in special situations
WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
This define will hence be redefined later (in section 4) if necessary

/* 4. FAST INPUT/OUTPUT OPERATIONS.
On some machines it is possible to improve speed by transferring the
bytes in the input and output arrays to and from the internal 32-bit
variables by addressing these arrays as if they are arrays of 32-bit
words. On some machines this will always be possible but there may
be a large performance penalty if the byte arrays are not aligned on
the normal word boundaries. On other machines this technique will
lead to memory access errors when such 32-bit word accesses are not
properly aligned. The option SAFE_IO avoids such problems but will
often be slower on those machines that support misaligned access
(especially so if care is taken to align the input and output byte
arrays on 32-bit word boundaries). If SAFE_IO is not defined it is
assumed that access to byte arrays as if they are arrays of 32-bit
words will not cause problems when such accesses are misaligned.

Issue Date: 20/12/2007
This file contains the code for declaring the tables needed to implement
AES. The file aesopt.h is assumed to be included before this header file.
If there are no global variables, the definitions here can be used to put
the AES tables in a structure so that a pointer can then be added to the
AES context to pass them to the AES routines that need them. If this
facility is used, the calling program has to ensure that this pointer is
managed appropriately. In particular, the value of the t_dec(in,it) item
in the table structure must be set to zero in order to ensure that the
tables are initialised. In practice the three code sequences in aeskey.c
that control the calls to aes_init() and the aes_init() routine itself will
have to be changed for a specific implementation. If global variables are
available it will generally be preferable to use them with the precomputed
STATIC_TABLES option that uses static global tables.
The following defines can be used to control the way the tables
are defined, initialised and used in embedded environments that
require special features for these purposes
the 't_dec' construction is used to declare fixed table arrays
the 't_set' construction is used to set fixed table values
the 't_use' construction is used to access fixed table values
256 byte tables:
t_xxx(s,box) => forward S box
t_xxx(i,box) => inverse S box
256 32-bit word OR 4 x 256 32-bit word tables:
t_xxx(f,n) => forward normal round
t_xxx(f,l) => forward last round
t_xxx(i,n) => inverse normal round
t_xxx(i,l) => inverse last round
t_xxx(l,s) => key schedule table
t_xxx(i,m) => key schedule table
Other variables and tables:
t_xxx(r,c) => the rcon table

Issue Date: 20/12/2007
The unsigned integer types defined here are of the form uint_<nn>t where
<nn> is the length of the type; for example, the unsigned 32-bit type is
'uint32_t'. These are NOT the same as the 'C99 integer types' that are
defined in the inttypes.h and stdint.h headers since attempts to use these
types have shown that support for them is still highly variable. However,
since the latter are of the form uint<nn>_t, a regular expression search
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
can be used to convert the types used here to the C99 standard types.

This file implements a random data pool based on the use of an external
entropy function. It is based on the ideas advocated by Peter Gutmann in
his work on pseudo random sequence generators. It is not a 'paranoid'
random sequence generator and no attempt is made to protect the pool
from prying eyes either by memory locking or by techniques to obscure
its location in memory.

/* ioapi_mem.c -- IO base function header for compress/uncompress .zip
files using zlib + zip or unzip API
This version of ioapi is designed to access memory rather than files.
We do use a region of memory to put data in to and take it out of. We do
not have auto-extending buffers and do not inform anyone else that the
data has been written. It is really intended for accessing a zip archive
embedded in an application such that I can write an installer with no
external files. Creation of archives has not been attempted, although
parts of the framework are present.

/*
bfinject - Inject shared libraries into running App Store apps on iOS 11.x < 11.2
https://github.com/BishopFox/bfinject
Carl Livitt @ Bishop Fox
Based on code originally by 10n1c: https://github.com/stefanesser/dumpdecrypted/blob/master/dumpdecrypted.c
Now with the following enhancements:
- Dump ALL encrypted images in the target application: the app itself, its frameworks, etc.
- Create a valid .ipa containing the decrypted binaries. Save it in ~/Documents/decrypted-app.ipa
- The .ipa can be modified and re-signed with a developer cert for redeployment to non-jailbroken devices
- Auto detection of all the necessary sandbox paths
- Converted into an Objective-C class for ease of use.
