AESHMAC512 DataTable Extension

Getting Started

To start using the DataTable extension functions add the NuGet package or reference the DLL file in your solution.

then add the following namespace.

using DotNetAES.Extensions;

DataTable Extension Functions

The following DataTable will be used in all examples below.

DataTable dt = new DataTable()
{
	Columns =
	{
		"column_one","column_two", "column_three", "column_four", "column_five", "column_iv",
	},
	Rows =
	{
		{ "one", "two", "three", "four", "five" },
		{ "one2", "two2", "three2", "four2", "five2" },
		{ "3one", "t3wo", "three3", "four3", "five3" },
		{ 2, 3, 4, 5, 6 },
		{ DateTime.Now, 2, 3 },
	}
};

To start using the DataTable extension functions add the following namespace.

using DotNetAES.Extensions;

AESHMAC512Encrypt

This function encrypts all the columns in a DataTable.

Syntax

DataTable AESHMAC512Encrypt(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

// Encrypts the DataTable and returns it
dt = dt.AESHMAC512Encrypt(AESHMAC512, cryptKey, authKey);

AESHMAC512EncryptIgnore

This function encrypts all the columns in a DataTable except all column names in the ignore list.

Syntax

DataTable AESHMAC512EncryptIgnore(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey, params string[] ignoreColumns)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

//Encrypts the DataTable and returns it
dt = dt.AESHMAC512EncryptIgnore(AESHMAC512, cryptKey, authKey, "column_two");

AESHMAC512EncryptOnly

This function encrypts only the specified columns in a DataTable.

Syntax

DataTable AESHMAC512EncryptOnly(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey, params string[] onlyColumns)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

//Encrypts the DataTable and returns it
dt = dt.AESHMAC512EncryptOnly(AESHMAC512, cryptKey, authKey, "column_two");

AESHMAC512Decrypt

This function decrypts all the columns in a DataTable.

Syntax

DataTable AESHMAC512Decrypt(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

//Decrypts the DataTable and returns it
dt = dt.AESHMAC512Decrypt(AESHMAC512, cryptKey, authKey);

AESHMAC512DecryptIgnore

This function decrypts all the columns in a DataTable except all column names in the ignore list.

Syntax

DataTable AESHMAC512DecryptIgnore(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey, params string[] ignoreColumns)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

//Decrypts the DataTable and returns it
dt = dt.AESDecryptIgnore(AESHMAC512, cryptKey, authKey, "column_two");

AESHMAC512DecryptOnly

This function decrypts only the specified columns in a DataTable.

Syntax

DataTable AESHMAC512DecryptOnly(this DataTable data, AESHMAC512 encryptionEngine, object cryptKey, object authKey, params string[] onlyColumns)

Example Usage

AESHMAC512  AESHMAC512  = new AESHMAC512 ();

// Generates a encryption key and the authentication key for the example
string cryptKey = AESHMAC512.CreateAESStringKey();
string authKey = AESHMAC512.CreateHMACAuthenticationStringKey();

//Decrypts the DataTable and returns it
dt = dt.AESHMAC512DecryptOnly(AESHMAC512, cryptKey, authKey, "column_two");
