Hello Alex,

It is always good to encrypt these login details): You can implement this in different ways. Here is a small code snippet which does exactly the same thing using JavaScript:

I have taken a look on this javascript earlier at http://www.webteacher.com/. This is a small example but it should get you started on encrypting these login details.

OK you want the code in C# means encryption at server side
Why you want to Encrypt the value at the server side do you want to store that value in database something like that
Best way is to have own algorithm to encrypt and decrypt the data

Thanks and Regards

Dim d As New EncryptedData
d.Algorithm.Name = CAPICOM_ENCRYPTION_ALGORITHM.CAPICOM_ENCRYPTION_ALGORITHM_3DES
d.Content = "hello"
d.SetSecret("23456", CAPICOM_SECRET_TYPE.CAPICOM_SECRET_PASSWORD)
Dim textenc As String = d.Encrypt(CAPICOM_ENCODING_TYPE.CAPICOM_ENCODE_BASE64)
Response.Write(textenc)

Dim d1 As New EncryptedData
d.Algorithm.Name = CAPICOM_ENCRYPTION_ALGORITHM.CAPICOM_ENCRYPTION_ALGORITHM_3DES
d.SetSecret("23456", CAPICOM_SECRET_TYPE.CAPICOM_SECRET_PASSWORD)
d.Decrypt(textenc)
Dim textdec As String = d.Content()
Response.Write(textdec)

Try the above , the value given as string in the function SetSecret is the key I am using , u can use anything. Add a reference to Capicom in ur project and then implement the same

string strencrypteddata="";
EncryptedData encryptdata = new EncryptedDataClass();

encryptdata.Algorithm.Name = CAPICOM.CAPICOM_ENCRYPTION_ALGORITHM.CAPICOM_ENCRYPTION_ALGORITHM_3DES;
encryptdata.Algorithm.KeyLength = CAPICOM.CAPICOM_ENCRYPTION_KEY_LENGTH.CAPICOM_ENCRYPTION_KEY_LENGTH_MAXIMUM;
encryptdata.SetSecret("dasdsads",CAPICOM.CAPICOM_SECRET_TYPE.CAPICOM_SECRET_PASSWORD);
encryptdata.Content = "hello";

strencrypteddata = encryptdata.Encrypt(CAPICOM.CAPICOM_ENCODING_TYPE.CAPICOM_ENCODE_BASE64);

decryption ::::

string strencrypteddata1;

EncryptedData encryptdata1 = new EncryptedDataClass();

encryptdata1.Algorithm.Name = CAPICOM.CAPICOM_ENCRYPTION_ALGORITHM.CAPICOM_ENCRYPTION_ALGORITHM_3DES;
encryptdata1.Algorithm.KeyLength = CAPICOM.CAPICOM_ENCRYPTION_KEY_LENGTH.CAPICOM_ENCRYPTION_KEY_LENGTH_MAXIMUM;
encryptdata1.SetSecret("dasdsads",CAPICOM.CAPICOM_SECRET_TYPE.CAPICOM_SECRET_PASSWORD);
encryptdata1.decrypt(strencrypteddata );

Response.Write(encryptdata1.Content);

I suppose u have ur solution opened in front of u , You will be able to see a references folder , right click , add reference . Click on the COM tab and there look for Capicom. select the same and then it will appear in the references folder in ur solution. Now in ur page add the line using Capicom.

Is it ok now
