AlphaCode | This class generates alphanumeric codes that are easy for humans to read. The codes are intended to be used as "document recovery codes" on printer-friendly versions of signed files, with codes that are (1) easy to read (2) easy to type back with low risk of mistaking similar characters such as "O" and "0" and (3) have a relatively high entropy for the size of the code (high number of possible codes relative to the size of the code, allowing the developer to choose a relatively small code size). |
