C# Class Akamai.Utils.ExtensionMethods

General utility functions needed to implement the NetStorageKit. Many of these functions are also available as standard parts of other libraries, but this package strives to operate without any external dependencies. Author: [email protected] (Colin Bendell)

Method Details

ComputeHash() public static method

Computes the hash of a given InputStream. This is a wrapper over the HashAlgorithm crypto functions.

public static ComputeHash ( this stream, ChecksumAlgorithm hashType = ChecksumAlgorithm.SHA256, long maxBodySize = null ) : byte[]
stream	this	the source stream. Use a MemoryStream if uncertain.
hashType	ChecksumAlgorithm	the Algorithm to use to compute the hash
maxBodySize	long
return	byte[]

ComputeKeyedHash() public static method

Computes the HMAC hash of a given byte[]. This is a wrapper over the Mac crypto functions.

public static ComputeKeyedHash ( this data, string key, KeyedHashAlgorithm hashType = KeyedHashAlgorithm.HMACSHA256 ) : byte[]
data	this	byte[] of content to hash
key	string	secret key to salt the hash. This is assumed to be UTF-8 encoded
hashType	System.Security.Cryptography.KeyedHashAlgorithm	determines which alogirthm to use. The recommendation is to use HMAC-SHA256
return	byte[]

GetEpochSeconds() public static method

determine the number of seconds since unix epoch

public static GetEpochSeconds ( this current ) : long
current	this	the date and time to convert
return	long

ReadExactly() public static method

Reads a stream up to @maxCount number of bytes. Less bytes will be returned if the end of the file is reached.

public static ReadExactly ( this stream, long maxCount ) : byte[]
stream	this	the stream to read
maxCount	long	the maximum number of bytes to read
return	byte[]

ToBase64() public static method

Base64-encode a byte array.

public static ToBase64 ( this data ) : string
data	this	byte array to encode.
return	string

ToByteArray() public static method

Retrieve the byte array for a string in UTF8 encoding

public static ToByteArray ( this data ) : byte[]
data	this	the data string
return	byte[]

ToHex() public static method

Hex encoding wrapper for a byte array. The output will be 2 character padded string in lower case.

public static ToHex ( this data ) : string
data	this	a byte array to encode. The assumption is that the string to encode /// is small enough to be held in memory without streaming the encoding
return	string

ToISO8601() public static method

format a date and time into ISO8601 style of "yyyyMMdd'T'HH:mm:ss+0000"

public static ToISO8601 ( this timestamp ) : string
timestamp	this	the date and time to convert
return	string

URLEncode() public static method

a utility method to uri encode a text string

public static URLEncode ( this data ) : string
data	this	the string
return	string
