+# SSZipArchive
+
+ZipArchive is a simple utility class for zipping and unzipping files on iOS and Mac.
+
+- Unzip zip files;
+- Unzip password protected zip files;
+- Create new zip files;
+- Append to existing zip files;
+- Zip files;
+- Zip-up NSData instances. (with a filename)
+
+## Installation and Setup
+
+*The main release branch is configured to support Objective C and Swift 3. There is a 'swift23' branch which is the latest branch but marked to compile for Swift 2.3.* 
+
+### CocoaPods
+
+`pod install SSZipArchive`
+
+### Carthage
+`github "ZipArchive/ZipArchive"`
+
+### Manual
+
+1. Add the `SSZipArchive` and `minizip` folders to your project.
+2. Add the `libz` library to your target
+
+SSZipArchive requires ARC.
+
+## Usage
+
+### Objective-C
+
+```objective-c
+// Create
+[SSZipArchive createZipFileAtPath: zipPath withContentsOfDirectory: sampleDataPath];
+
+// Unzip
+[SSZipArchive unzipFileAtPath:zipPath toDestination: unzipPath];
+```
+
+### Swift
+
+```swift
+// Create
+SSZipArchive.createZipFileAtPath(zipPath, withContentsOfDirectory: sampleDataPath)
+
+// Unzip
+SSZipArchive.unzipFileAtPath(zipPath, toDestination: unzipPath)
+```

-# SSZipArchive
-
-SSZipArchive is a simple utility class for zipping and unzipping files. Features:
-
-* Unzipping zip files
-* Unzipping password protected zip files
-* Creating zip files
-* Appending to zip files
-* Zipping files
-* Zipping NSData with a filename
-* Works in ARC and non-ARC projects
-
-## Adding to your project
-
-1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.
-2. Add the `libz` library to your target
-
-You don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.
-
-## Usage
-
-``` objective-c
-// Unzipping
-NSString *zipPath = @"path_to_your_zip_file";
-NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
-[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
-
-// Zipping
-NSString *zippedPath = @"path_where_you_want_the_file_created";
-NSArray *inputPaths = [NSArray arrayWithObjects:
-                       [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
-                       [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
-                       nil];
-[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];
-```

+
+3. Push the pod to the trunk 
+
+    - *pod trunk push SSZipArchive.podspec*
+    
+4. Create a Carthage framework archive
+
+    - *carthage build --no-skip-current*
+    - *carthage archive ZipArchive*
+    
+5. Attach archive to the release created in step 1.

+ 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.

+  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]);

+/*  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

+    (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

+
+ 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
+ FIXED_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
