Here` how u can encrypt and decrypt strings.. First add a refrence to Capicom in COM tab. Add a namespace using CAPICOM; To encrypt: 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 = PlainTexttxt.Text; strencrypteddata = encryptdata.Encrypt(CAPICOM.CAPICOM_ENCODING_TYPE.CAPICOM_ENCODE_BASE64); EncryptedText.Text=strencrypteddata; To decrypt: 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(EncryptedText.Text); Response.Write(encryptdata1.Content); Make an aim with a pain,your efforts won`t go in vain

Hi, An easy encryption and decryption method. public static string Encrypt(string valueToEncrypt) { byte []b; b = ASCIIEncoding.ASCII.GetBytes(valueToEncrypt); return Convert.ToBase64String(b); } public static string Decrypt(string valueToDecrypt) { byte []b; b = Convert.FromBase64String(valueToDecrypt); return ASCIIEncoding.ASCII.GetString(b); }
