To use the following methods, you need to use the version 2.6 or higher of LeoCorpLibrary, and put this on top of your code file:

C#

using LeoCorpLibrary;

VB

Imports LeoCorpLibrary

This function is available in version 2.6 and higher.

The Encrypt() method allows you to encrypt a string. It returns a string value.

It's in:

LeoCorpLibrary.Crypt.Encrypt()

This method has a few arguments:

Here's an example of usage:

C#

string s = "Hello!";
string encrypted = LeoCorpLibrary.Crypt.Encrypt(s, "ABC123");

// Output: jqPW4uxt8hk=

VB

Dim s As String = "Hello!"
Dim encrypted As String = LeoCorpLibrary.Crypt.Encrypt(s, "ABC123")

' Output: jqPW4uxt8hk=

This function is available in version 2.6 and higher.

The Decrypt() method allows you to decrypt an encrypted string. It returns a string value.

It's in:

LeoCorpLibrary.Crypt.Decrypt()

This method has a few arguments:

Here's an example of usage:

C#

string encrypted = "jqPW4uxt8hk=";
string decrypted = LeoCorpLibrary.Crypt.Decrypt(encrypted, "ABC123");

// Output: Hello!

VB

Dim encrypted As String = "jqPW4uxt8hk="
Dim decrypted As String = LeoCorpLibrary.Crypt.Decrypt(encrypted, "ABC123")

' Output: Hello!

This function is available in version 3.3 and higher.

The EncryptRSA() method allows you to ecnrypt a string using RSA encryption. It returns a byte[] value.

It's in:

LeoCorpLibrary.Crypt.EncryptRSA()

This method has a few arguments:

Here's an example of usage:

C#

using System.Security.Cryptography;

RSACryptoServiceProvider cryptoServiceProvider = new RSACryptoServiceProvider();

string str = "LeoCorpLibrary";
byte[] encrypt = Crypt.EncryptRSA(str, cryptoServiceProvider.ExportParameters(false));

Console.WriteLine($"Raw: {str}\nEncrypted: {Crypt.ConvertBytesToString(encrypt)}");

VB

Imports System.Security.Cryptography

Dim cryptoServiceProvider As RSACryptoServiceProvider = New RSACryptoServiceProvider()

Dim str As String = "LeoCorpLibrary"
Dim encrypt As Byte() = Crypt.EncryptRSA(str, cryptoServiceProvider.ExportParameters(False))

Console.WriteLine($"Raw: " + str + "\nEncrypted: " + Crypt.ConvertBytesToString(encrypt))

This function is available in version 3.3 and higher.

The DecryptRSA() method allows you to decrypt a string using RSA encryption. It returns a byte[] value.

It's in:

LeoCorpLibrary.Crypt.DecryptRSA()

This method has a few arguments:

Here's an example of usage:

C#

using System.Security.Cryptography;

RSACryptoServiceProvider cryptoServiceProvider = new RSACryptoServiceProvider();

string str = "LeoCorpLibrary";
byte[] encrypt = Crypt.EncryptRSA(str, cryptoServiceProvider.ExportParameters(false));
byte[] decrypt = Crypt.DecryptRSA(encrypt, cryptoServiceProvider.ExportParameters(true));

Console.WriteLine($"Raw: {str}\nEncrypted: {Crypt.ConvertBytesToString(encrypt)}\nDecrypted: {Crypt.ConvertBytesToString(decrypt)}");

VB

Imports System.Security.Cryptography

Dim cryptoServiceProvider As RSACryptoServiceProvider = New RSACryptoServiceProvider()

Dim str As String = "LeoCorpLibrary"
Dim encrypt As Byte() = Crypt.EncryptRSA(str, cryptoServiceProvider.ExportParameters(False))
Dim decrypt As Byte() = Crypt.DecryptRSA(encrypt, cryptoServiceProvider.ExportParameters(True))

Console.WriteLine($"Raw: " + str + "\nEncrypted: " + Crypt.ConvertBytesToString(encrypt) + "\nDecrypted: " + Crypt.ConvertBytesToString(decrypt))

This function is available in version 3.3 and higher.

The EncryptAES() method allows you to encrypt a string using AES encryption. It returns a string value.

It's in:

LeoCorpLibrary.Crypt.EncryptAES()

This method has a few arguments:

Here's an example of usage:

C#

string str = "LeoCorpLibrary";
string encrypt = Crypt.EncryptAES(str, "key");
string decrypt = Crypt.DecryptAES(encrypt, "key");

Console.WriteLine($"Raw: {str}\nEncrypted: {encrypt}");

VB

Dim str As String = "LeoCorpLibrary"
Dim encrypt As String = Crypt.EncryptAES(str, "key")
Dim decrypt As String = Crypt.DecryptAES(encrypt, "key")
Console.WriteLine("Raw: " + str + "\nEncrypted: " + encrypt)

This function is available in version 3.3 and higher.

The DecryptAES() method allows you to decrypt a string using AES ecnryption. It returns a string value.

It's in:

LeoCorpLibrary.Crypt.Decrypt()

This method has a few arguments:

Here's an example of usage:

C#

string str = "LeoCorpLibrary";
string encrypt = Crypt.EncryptAES(str, "key");
string decrypt = Crypt.DecryptAES(encrypt, "key");

Console.WriteLine($"Raw: {str}\nEncrypted: {encrypt}\nDecrypted: {decrypt}");

VB

Dim str As String = "LeoCorpLibrary"
Dim encrypt As String = Crypt.EncryptAES(str, "key")
Dim decrypt As String = Crypt.DecryptAES(encrypt, "key")

Console.WriteLine("Raw: " + str + "\nEncrypted: " + encrypt + "\nDecrypted: " + decrypt)
