Makes calculating digests easy.

Supports:

- SHA-224

- SHA-256

- SHA-386

- SHA-512

- SHA-1

- MD2

- MD4

- MD5

## Use

`CBHDigestKit` extends `NSData` and `NSString` with a category adding methods for several digests and converting from `bytesToHex`.

#### Example:

Compute the SHA-256 digest of a `NSString`:

```objective-c

NSData *digest = [@"This is a string." sha256UsingEncoding:NSUTF8StringEncoding];

```

Compute the SHA-256 digest of a `NSData`:

```objective-c

NSData *digest = [[NSData dataWithContentsOfFile:@"/etc/hosts"] sha256];

```

Efficiently compute the  SHA-256 digest of a file:

```objective-c

NSInputStream *fileStream = [NSInputStream inputStreamWithFileAtPath:@"/etc/hosts"];

NSData *digest = [CBHDigester digestStream:fileStream usingAlgorithm:CBHDigestAlgorithm_SHA256];

```

Compute and print a digest using an arbitrary algorithm:

```objective-c

CBHDigestAlgorithm algorithm = ...

NSData *data = [NSData dataWithContentsOfFile:@"/etc/hosts"];

NSData *digest = [data digestUsingAlgorithm:algorithm];

NSLog(@"0x%@", [digest encodeAsHexadecimal]);

```
