The Blocks will produce Random Text, Hashs and implement Encryption / Decryption

HASH Example

    public void SHA256HashExample()    
    {
        var input = "test";
        var base64hasHResult = SHA256Hash.Instance.GenerateHashAsBase64(input);
        Console.WriteLine(base64hasHResult);
        // will produce n4bQgYhMfWWaL+qgxVrQFaO/TxsrC4Is0V1sFbDwCgg= 
        var Hexadecimal = SHA256Hash.Instance.GenerateHashAsHexadecimal(input);
        Console.WriteLine(Hexadecimal);
        // will produce 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08
    }

Encryption Example

    public void EncryptionExample()
    {
        // Create a new AesCrypto instance seeded with "123" as salt for the initialization vector
        // we use the salt such that the same encrypted value will product a difference cypher text
        // this is allows us to seed each SymmetricEncryption to a different value if needed like 
        // for example each customer can have their own salt value
        ISymmetricEncryption targetEncrypter = new AesCrypto("123");

        Console.WriteLine(targetEncrypter.Encrypt("OriginalText", "secret"));
        // output will be   "1vHyXdWtrigZm5S5Kbksm/A0UyJ7Z4mERnZiFjypQNA="
        Console.WriteLine(targetEncrypter.Decrypt("1cdFBg67qpr6XKgDXJlf4Y7GbUZv5DiMV6ynjQ2PwKU=", "secret"));
        // output will be  OriginalText
        ISymmetricEncryption targetEncrypter2 = new AesCrypto("1234");
        Console.WriteLine(targetEncrypter2.Encrypt("OriginalText", "secret"));
        // output will be   "FpEv1Eh9qj0c7qeHmBOz4xABCbLGz5ljLgvgNVQOLBo="
        Console.WriteLine(targetEncrypter2.Decrypt("FpEv1Eh9qj0c7qeHmBOz4xABCbLGz5ljLgvgNVQOLBo=", "secret"));
        // output will be OriginalText 
    }

Random Text Example

    public void PasswordGeneratorExample()
    {
        var passwordGenerator = new RandomTextGenerator(new RandomTextGeneratorSettings { AllowedChars = RandomTextGeneratorSettings.ASCIIPass });
        string example = passwordGenerator.Generate(12);
        Console.WriteLine(example);
        // exmaple output:  |NAQr%gpyVb2
        // Will Producte Randon password of 12 charchers useing the CharSet
        //  ASCIIPass = " !\"#$%&()*+-/2345679:;<=>?@ACDEFGHJLKLMNPQRSTUVXYZ[\\]^_abcdefghklmnopqrstuvxyz{|}~"
        // This exludes ambigious characters like '1' and 'l' or '0' and 'O' from the generated password
    }
