Base64 uses a 65 character subset of US-ASCII, allowing 6 bits for each character so the character m with a Base64 value of 38, when represented in binary form, is 100110. When a text string, letâ„¢s say mne is encoded this is what happens : The text string is converted into its US-ASCII value. (In US-ASCII each character is assigned a value)
