Encrypt Method
Encrypts a buffer.
Syntax
symmetriccrypto.encrypt(buffer_Buffer, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err, buffer){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'buffer' is the value returned by the method.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
Use this method to encrypt a byte array and get the protected message in another byte array.
Specify the encryption key in Key property before calling this method.
This is a one-off encryption method. Don't use it with granular per-block methods(EncryptInit, EncryptUpdate, EncryptFinal).
