![]() Sending information in binary format can sometimes be risky since not all applications or network systems can handle raw binary. You can use any online text to Base64 converter to verify this result. Using this encoding table we can see that the string "Go win" is encoded as "R28gd2lu" using Base64. Here you can see that decimal 17 corresponds to "R", and decimal 54 corresponds to "2", and so on. These decimal values have been given below: Binary Decimal Now for each chunk above, we have to find its decimal value. You won't always be able to divide up the data in to full sets of 6 bits, in which case you'll have to deal with padding. Note that some implementations of Base64 uses different special characters than "+" and "/".Ĭoming back to the example, let us break our 8 bit data into chunks of 6 bits. This is because Base64 format only has 64 characters: 26 uppercase alphabet letters, 26 lowercase alphabet letters, 10 numeric characters, and the "+" and "/" symbols for new line.īase64 doesn't use all the ASCII special characters, but only these few. However as we said earlier, Base64 converts the data in 8 bit binary form to chunks of 6 bits. You can see here that each character is represented by 8 bits. The first step is to convert this string into binary. Suppose we have string "Go win" and we want to convert it into Base64 string. Find the Base64 symbol for each of the decimal values via a Base64 lookup tableįor a better understanding of this concept, let's take a look at an example. ![]()
