Methods

EncryptAes(str, key)

Definitions

Encrypts a string using AES encryption. Returns the encrypted content as a string as well.

Arguments

Type	Name	Meaning
string	str	The text to encrypt.
string	key	The encryption key. This is the same key that will be used to decrypt the text.

Usage

using PeyrSharp.Core;

string text = "Hello, world!";
string encrypted = Crypt.EncryptAes(text, "password");
// encrypted = 8U0HRr7pCIdbvBIquiJaLc00fyBjXDb9sLflk5anIi8=

EncryptRsa(str, rsaParameters)

Definitions

Encrypts a string using RSA encryption. Returns the encrypted content as an array of byte (byte[]).

Arguments

Type	Name	Meaning
string	str	The text to encrypt.
RSAParameters	rsaParameters	The RSA key.

Usage

using PeyrSharp.Core;
using System.Security.Cryptography;

string text = "Hello, world!";

// Create the RSA key
RSACryptoServiceProvider cryptoServiceProvider = new RSACryptoServiceProvider();

// Encrypt using RSA
string encrypted = Crypt.EncryptRsa(text, cryptoServiceProvider.ExportParameters(false));

Encrypt3Des(source, key)

Definitions

Encrypts a string using AES encryption. Returns the encrypted content as a string as well.

Arguments

Type	Name	Meaning
string	source	The text to encrypt.
string	key	The encryption key. This is the same key that will be used to decrypt the text.

Usage

using PeyrSharp.Core;

string text = "Hello, world!";
string encrypted = Crypt.Encrypt3Des(text, "password");
// encrypted = bxceEpCfRlbyYdPggAu+Cw==

DecryptAes(str, key)

Definitions

Decrypts a string using AES encryption. Returns the decrypted content as a string as well.

Arguments

Type	Name	Meaning
string	str	The text to decrypt.
string	key	The encryption key that was used during the encryption process.

Usage

using PeyrSharp.Core;

string encrypted = "6NvvTBntd2PdFxXzVbccLw==";
string text = Crypt.DecryptAes(encrypted, "password");
// text = Hello!

DecryptRsa(encrypted, rsaParameters)

Definitions

Decrypts a string using AES encryption. Returns the decrypted content as a string as well.

Arguments

Type	Name	Meaning
byte[]	encrypted	The text to decrypt.
RSAParameters	rsaParameters	The encryption key that was used during the encryption process.

Usage

using PeyrSharp.Core;
using System.Security.Cryptography;

RSACryptoServiceProvider cryptoServiceProvider = new RSACryptoServiceProvider();
byte[] e = Crypt.EncryptRsa("Hello", cryptoServiceProvider.ExportParameters(false));

string decrypted = Crypt.DecryptRsa(e, cryptoServiceProvider.ExportParameters(true));
// decrypted = Hello

Decrypt3Des(str, key)

Definitions

Decrypts a string using 3-DES encryption. Returns the decrypted content as a string as well.

Arguments

Type	Name	Meaning
string	encrypt	The text to decrypt.
string	key	The encryption key that was used during the encryption process.

Usage

using PeyrSharp.Core;

string encrypted = "AvuLd4LUxRU=";
string text = Crypt.Decrypt3Des(encrypted, "123");
// text = Hello
