Hi I'm traying to use this library but I got this error using the same sample functions.
the release of this library is 1.0

   Dim encryptedData() As Byte = EncryptText(root.Get("DATA"),"xx1100")

Sub EncryptText(ff As String, XPASSWORD As String) As Byte()
 Dim c As B4XCipher
 Return c.Encrypt(ff.GetBytes("utf8"), XPASSWORD)
End Sub
Sub DecryptText(EncryptedData() As Byte, XPASSWORD As String) As String
 Dim c As B4XCipher
 Dim b() As Byte = c.Decrypt(EncryptedData, XPASSWORD)
 Return BytesToString(b, 0, b.Length, "utf8")
End Sub
