Class Encryption - Westwind Utilities

Class Encryption

Class that provides a number of encryption utilities.

System.Object
Westwind.Utilities.Encryption

public static class Encryption : object

Remarks

For best compatibility across platforms of the Encrypt/Decrypt methods use overloads that use the key as a byte[24] value rather than string or other sized buffers.

Class Members

Member		Description
	EncryptionKey	Replace this value with some unique key of your own Best set this in your App start up in a Static constructor
	EncryptionKeySize	Global configuration propery that can be overridden to set the key size used for Encrypt/Decript operations. Choose between 16 bytes (not recommended except for backwards compatibility) or 24 bytes (works both in NET Full and NET Core)
	BinaryToBinHex	Converts a byte array into a BinHex string. Example: 01552233 where the numbers are packed byte values. public static string BinaryToBinHex(Byte[] data)
	BinHexToBinary	Turns a BinHex string that contains raw byte values into a byte array public static Byte[] BinHexToBinary(string hex)
	ComputeHash	Generates a hash for the given plain text value and returns a base64-encoded result. Before the hash is computed, a random salt is generated and appended to the plain text. This salt is stored at the end of the hash value, so it can be used later for hash verification. public static string ComputeHash(string plainText, string hashAlgorithm, Byte[] saltBytes, bool useBinHex) public static string ComputeHash(string plainText, string hashAlgorithm, string salt, bool useBinHex) public static string ComputeHash(Byte[] byteData, string hashAlgorithm, Byte[] saltBytes, bool useBinHex)
	DecryptBytes	Decrypts a Byte array from DES with an Encryption Key. public static Byte[] DecryptBytes(Byte[] decryptBuffer, string encryptionKey) public static Byte[] DecryptBytes(Byte[] decryptBuffer, SecureString encryptionKey) public static Byte[] DecryptBytes(Byte[] decryptBuffer, Byte[] encryptionKey, CipherMode cipherMode) public static Byte[] DecryptBytes(string decryptString, string encryptionKey, bool useBinHex) public static Byte[] DecryptBytes(string decryptString, SecureString encryptionKey, bool useBinHex)
	DecryptString	Decrypts a string using DES encryption and a pass key that was used for encryption. public static string DecryptString(string decryptString, string encryptionKey, bool useBinHex) public static string DecryptString(string decryptString, SecureString encryptionKey, bool useBinHex) public static string DecryptString(string decryptString, Byte[] encryptionKey, bool useBinHex)
	EncryptBytes	Encodes a stream of bytes using DES encryption with a pass key. Lowest level method that handles all work. public static Byte[] EncryptBytes(Byte[] inputBytes, string encryptionKey) public static Byte[] EncryptBytes(Byte[] inputBytes, SecureString encryptionKey) public static Byte[] EncryptBytes(Byte[] inputBytes, Byte[] encryptionKey, CipherMode cipherMode) public static Byte[] EncryptBytes(string inputString, string encryptionKey)
	EncryptString	Encrypts a string using Triple DES encryption with a two way encryption key.String is returned as Base64 or BinHex encoded value rather than binary. public static string EncryptString(string inputString, Byte[] encryptionKey, bool useBinHex) public static string EncryptString(string inputString, string encryptionKey, bool useBinHex) public static string EncryptString(string inputString, SecureString encryptionKey, bool useBinHex)
	GetChecksumFromBytes	Create a SHA256 or MD5 checksum from a bunch of bytes public static string GetChecksumFromBytes(Byte[] fileData, string mode)
	GetChecksumFromFile	Creates an SHA256 or MD5 checksum of a file public static string GetChecksumFromFile(string file, string mode)
	GZipFile	Encodes one file to another file that is gzip compressed. File is overwritten if it exists and not locked. public static bool GZipFile(string Filename, string OutputFile)
	GZipMemory	GZip encodes a memory buffer to a compressed memory buffer public static Byte[] GZipMemory(Byte[] buffer) public static Byte[] GZipMemory(string Input) public static Byte[] GZipMemory(string Filename, bool IsFile)
