Question

If I started with the three ASCII characters "CSP", how many Base64 values will I be left with at the end?

Answer 1

When the ASCII characters "CSP" are encoded in Base64, you will have four Base64 values, as the process converts three bytes into four Base64 characters.

Step-by-step explanation:

If you start with the three ASCII characters "CSP", then encode them to Base64, you will end up with four Base64 values. This happens because Base64 encoding takes each set of three bytes (24 bits) and converts them into four Base64 characters. Each Base64 character represents 6 bits of data. Here's how the process works in steps:

• Convert the ASCII characters to their binary representations.
• Group the binary representation into 24 bits (three bytes).
• Divide the 24 bits into four groups of 6 bits.
• Map each group of 6 bits to a corresponding Base64 character.

The ASCII values for "C", "S", and "P" are 67, 83, and 80 respectively. When you convert these values to binary and then to Base64, "CSP" would be represented as "Q1NQ" in Base64 format. Therefore, you will have four Base64 characters at the end of this encoding process.
